Description

[0001] SENSOR. DEVICE, SYSTEM AND METHOD FOR DETERMINING TEMPERATURES OF DIFFERENT REGIONS OF A TESTICLE

[0002] TECHNICAL FIELD

[0003] The present disclosure relates to sensor devices for determining temperatures of regions of a given body part wherein the body part is at least one testicle. Moreover, the present disclosure relates to systems for determining temperatures of regions of a given body part wherein the body part is at least one testicle. Furthermore, the present disclosure relates to methods for determining temperatures of regions of a given body part wherein the given body part is at least one testicle. Furthermore, the present disclosure relates to computer-readable storage mediums comprising software applications which when executed by processing arrangements, cause the processing arrangement to execute steps of methods.

[0004] BACKGROUND

[0005] The functionality of the testicles is known to be optimal at a temperature approximately 2-4°C below the core body temperature. Elevated temperatures have been associated with various diseases. Existing methods for detecting and diagnosing abnormalities in the testicles are often resource-intensive, time-consuming, and require clinical expertise in terms of their invasive nature, need for a clinical setting, and implementation by a medically trained practitioner.

[0006] Common diagnostic techniques for testicular abnormalities include physical examination, blood tests for tumour markers, histology, and various imaging procedures such as ultrasound. Physical examination involves palpitating, manual probing for lumps and identification of areas of discolouration, swelling, skin texture changes (typically associated withpotential abnormalities), though it can be subjective. Moreover, physical examinations require utmost care to be taken to avoid heat emission, as the testicles are sensitive to temperature changes. Often identification of these features may not be early enough, and the disease may have spread. Moreover, blood tests for tumour markers such as alphafetoprotein (AFP), human chorionic gonadotrophin (HCG), and lactate dehydrogenase (LDH) are employed, but they may lack specificity for certain types of testicular cancer. Hence, markers tested may not be suitable for all types of conditions. Histology, involving the examination of a biopsy, can be invasive and may lead to complications. A biopsy may injure the testicle and may cause it to spread, so typically a testicular lump is examined by histology by removing the testicle completely (the procedure is called orchidectomy).

[0007] Ultrasound and Doppler ultrasound (for mapping blood flow inside the scrotum) are used for imaging, but they do not inherently detect abnormalities based on temperature variations.

[0008] In a clinical setting the temperature and humidity of the examination room must be controlled so that the patient is not stressed, patients must refrain from exposure to direct sunlight, use of cosmetics (no intervention from hairs), antiperspirants or deodorants immediately before thermography examinations. Thermal acclimation time is required for patients to achieve thermal equilibrium. The clinic in which the infrared procedure is carried out must be free from any secondary infrared sources like incandescent lamp or direct sunlight. Thermographic findings are in general compared with other clinical findings to assess for possible correlations.

[0009] For example, liquid crystal thermography is time consuming, has low thermal sensitivity (~0.3-1.0C) and poor spatial resolution (>5mm). This encompasses a thermometer that consists of rubber sheets which contains thermochromic cholesteric liquid crystals arranged in layers.Rubber sheets provide good contact with the curved body surface. The liquid crystals display colours due to a change in temperature, the resulting pattern represents the temperature distribution of the body surface. Additionally, medical infrared thermography_employs thermal radiation emitted by a surface, the emitted radiation is detected by an infrared camera and the intensity of the emitted radiation is converted to temperature. This measures the temporal variation of temperature distribution as a series of thermal images are acquired which constitute a time series in temperature. The dynamics is quantitively analysed by performing Fast Fourier transform (FFT) of the time series of temperature.

[0010] Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks.

[0036] determining the temperatures of different regions of the body part, based on the pixel values of pixels in the at least one image segment to form a temperature profile of the body part.

[0037] The disclosed method accurately detects changes in different regions of the testicle in a safe, user-friendly, accurate and reliable manner at home, in a research laboratory or in the clinic to supplement more advanced and disease-specific clinical investigations. The method is easy to implement, provides fast indicative results, and does not require complex or expensive equipment. Furthermore, there is no complexity in the use and there are no harmful effects.

[0038] In a fourth aspect, the present disclosure provides a computer-readable storage medium comprising at least one software application comprising instructions for determining a temperature of a region of a body part, which when executed by a processing arrangement, causes the processing arrangement to execute steps of the aforementioned method of third aspect.

[0039] Throughout the present disclosure, the term "sensor device" as used herein refers to a temperature-sensing device. The sensor device is suitable designed to be placed against a given body part, such as a testicle, such that it at least partially covers the given body part. It willbe appreciated that in this regard, the sensor device is in form of a patch or contoured to be accommodated on the given body part such that it covers the whole or a part of the body part for determining temperatures of one or more regions of the given body part.

[0040] It will be appreciated that teachings of the present disclosure are not limited to any particular body part. However, the at least one sensor device of the present disclosure can be implemented on any part of the body to detect any potential abnormalities based upon a temperature in that part. For example, when the sensor device is in contact with an area of skin of a given body part the temperature profile of the area may indicate a level of fatigue and / or a potential rupture of muscle in an underlying muscle. It may also indicate poor blood circulation, poor nerve function, inflammation or any other function that causes a local increase in temperature.

[0041] The sensor device can be in contact with the body part of the user for a predefined time period. In an instance, when the body part is the at least one breast, the predefined time period may lie in a range of 5 minutes to 30 minutes. The period of time may be lower, for example, 30 seconds, 1 minute, 2 minutes etc. It is sufficient for the contact of the sensor device with the given body part to be made for period of time that allows the sensor device to indicate a temperature higher than adjacent regions or areas of a given body part. This also applies wherein the give body part is wounded and therefore, the sensor device senses temperatures from any surface. For example, the sensor device senses temperatures of a wound dressing when the wound dressing is in contact with a body part.

[0042] In another instance, when the body part is one of: the at least one portion of the skin, the at least one foot, the predefined time period may lie in a range of 5 minutes to 15 minutes. As an example, when the body part is one of: the at least one portion of the skin, the at least one foot, thepredefined time period may be 10 minutes. In yet another instance, when the body part is the at least one testicle, the predefined time period may lie in a range of 5 minutes to 20 minutes. As an example, when the body part is the at least one testicle, the predefined time period may be 15 minutes.

[0043] The sensor device comprises a first layer with a first side and a second side opposite to the first side. The first layer may cover the whole of the given body part or may not cover the entire the given body part. The sensor device may be available in a range of sizes. The first layer of the sensor device may be thin, it may have a low threshold of pressure and may be in a form suitable for at least partially covering the body part. The term "first side" refers to a surface of the first layer that faces the body part, when the sensor device is in use. The term "second side" refers to another surface of the first layer which is opposite to the first side and faces away from the body part. The first layer of the sensor device is not in contact with the skin and may display a logo, a marketing brand name or a design. The first layer may be composed of a soft material that may display a logo, a marketing brand name, a design and / or a protective covering.

[0044] The first layer of the sensor device does not cause a temperature change when touched.

[0045] The first layer may be made of a medical grade flexible material (includes, but is not limited to, cotton, a polymer, polyester) that does not wrinkle, fold or break. The first layer may be made of a material made of a polymer substrate material which offers flexibility, thermal stability and chemical resistance. Examples of such polymer substrate material may include, but are not limited to, Biaxially Oriented Polypropylene (BOPP), Polyethylene Terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), and Polyimide (PI).Moreover, the sensor device comprises a second layer arranged on the first side of the first layer, the second layer comprising at least one temperature-sensitive indicator. The term "second layer" as used herein refers to a substrate layer with a first thermochromic side comprising at least one temperature-sensitive indicator and a second side opposite to the first side, wherein the second side of the second layer contacts the first side of the first layer. The term "temperature-sensitive indicator" as used herein refers to an element that detects and measures a temperature of the body part. The at least one temperature-sensitive indicator may change composition or physical state in response to heat. For instance, the temperature-sensitive indicators could change from an opaque solid to a translucent liquid which thereby allows the visual observation of the temperature. The second layer may contain statechanging substances that emit a colour corresponding to a temperature. The second layer may be implemented as a plastic film and the at least one temperature-sensitive indicator may be implemented as a coating on a first side of the plastic film to result in a thermochromic film, while a second side or a colour backing side (opposite the first side) of the second layer contacts the first side of the first layer. An entire surface of the first side of the second layer may be coated with the temperature-sensitive indicator, i.e., a sheet of a colour-changing material. Typically, such thermochromic films (namely, films bearing at least one temperaturesensitive indicator on a thermochromic (first) side thereof) are designed to undergo a reversible colour change (resulting in a colour map visible through the colour backing side of the film (i.e., the second layer)) at a specific temperature range. In this regard, the second layer may include one large temperature-sensitive indicator or a plurality of small temperature-sensitive indicators. As an example, the sensor device has three temperature-sensitive indicators. Each of the three temperaturesensitive indicators are configured to determine the temperatures of the different regions of the body part.A technical benefit of this is that the at least one temperature-sensitive element efficiently determines the temperatures of different regions of the body part providing accurate results.

[0046] The material of the first layer holding the second layer thereon may be a poor conductor of heat so that heat is not conducted away from the thermochromic film and the colour change is retained for longer.

[0047] When the second layer is implemented as a thermochromic film, the colour displayed corresponding to a temperature change is visible on the thermochromic film. An image of a colour map displayed on the thermochromic film first layer can be captured by a camera. The camera is communicably coupled to a processing unit (namely at least one processor) which assigns values to the pixels of the image and thus determines the temperature of the different regions of the given body parts. The results are processed and will be available to the user via a device specific software application.

[0048] When placed on the outer surface of the testicle, the sensor device, can detect changes in temperature in areas of the testicle. The sensor device is suitable for the detection of any excess heat producing abnormality in the testicle. Moreover, testicular abnormalities may be detected by changes in temperature. The results can be viewed directly on the external device or entered on a mobile application or on a webpage for immediate interpretation. The sensor device provides a safe, non-invasive and cost-effective method for routinely detecting abnormalities that can be used in conjunction with or to supplement already established investigative procedures including clinical testicle examinations.

[0049] The at least one temperature-sensitive indicator may be a replaceable irreversible temperature-sensitive indicator The irreversible temperaturesensitive indicator could be in a form that can be moulded around the given body parts or within a pad or soft material or the first layer. The thermally responsive materials or temperature responsive substance orthe at least one temperature-sensitive indicator may be a thermosensitive fluid or a thermosensitive compound. Optionally, the thermosensitive fluid could be a liquid substance that undergoes a change in a physical property based on the different temperatures of different regions of the given body part.

[0050] The thermally responsive substance may be coated onto the temperature-sensitive indicator which can be adhered to the first side of the first layer. The irreversible temperature-sensitive indicators may have applications outside this device, and can be used on food packaging, packaging of medical / laboratory solutions or storage containers for biological entities (such as blood, organs, antibodies) for instance.

[0051] The temperature-sensitive indicator may comprise at least one of:

[0052] a thermosensitive fluid selected from at least one of: a thermosensitive ink and a thermosensitive pigment comprising;

[0053] a thermosensitive compound selected from at least one of: a crystalline organic compound, cholesteric liquid crystalline formulations, encapsulated cholesteric liquid crystals, N-phenylbenzylamine, Bromo-p-Xylene, Tetradecanol, solid solutions of halogenated nitrobenzenes including ortho-chlorinitrobenzene and ortho-bromonitrobenzene, or other thermochromic compounds, wherein cholesteric liquid crystalline formulations comprise cholesteric esters selected from at least one of: cholesteryl pelargonate, cholesteryl chloride, oleyl cholesteryl carbonate, and other colour changing compounds. The thermosensitive fluid could be, but not limited to, a thermosensitive ink or a thermosensitive pigment.

[0054] In this regard, the temperature-sensitive element may be a thermochromic ink, which could be a dark colour, for example black, when the sensor device is not in use, provided that the ambient temperature is lower than or close to (for example, within 1°C) lower limit of the range of operation of the temperature-sensitive material. Thetemperature-sensitive element may be an irreversible temperaturesensitive indicator, such as an adapted thermometric device with a memory feature that contains cholesteric liquid crystalline formulations that display colours indicative of a defined temperature range. The irreversible temperature-sensitive indicator may contain cholesteric liquid crystalline formulations that indicate when the maximum temperature (thermokinetic limit) of the given body part has been exceeded.

[0055] The thermosensitive compound could be a liquid substance, a powder substance or a solid substance, that undergoes changes in physical properties in a similar manner as the thermosensitive fluid. The thermosensitive compound could be, but not limited to, a crystalline organic compound, encapsulated cholesteric liquid crystals, N-phenylbenzylamine, Bromo-p-Xylene, Tetradecanol or a thermochromic compound.

[0056] The temperature responsive substances may be solid solutions of halogenated nitrobenzenes such as ortho-chlorinitrobenzene and orthobromonitrobenzene. The second layer may change composition or physical state in response to heat. For instance, the second layer could change from an opaque solid to a translucent liquid which thereby allows the visual observation of the temperature. As an additive, the temperature responsive substance may contain an organic compound such as a dye (for example methyl violet), dibenzyl succinate, phenyl salicate and dibenzyl which is stable over long periods of time, soluble in the temperature responsive substance and responsive to a change in the physical state of said substance. The change in state corresponds to the known melting points of the temperature responsive substances. Furthermore, the heat required for a change in state is minimal. Furthermore, certain organic compounds such may have a lower melting point than the temperature responsive substances with which they are combined and thus upon heating, the generation of additional liquid from an organic compound can facilitate the visual detection of thetemperature corresponding to the change of state of the temperature responsive substance. This decreases the time required for visual detection of the temperature of the region of the given body part.

[0057] When the organic compound is a dye, only dyes such as oil-soluble dyes that do not adversely affect the melting ranges of the temperature responsive substances may be used. Visual detection of any colour change may be enhanced by the addition of cationic surfactants such as fatty acid nitrogen derivatives, non-ionic surfactants such as polyethyleneoxy derivatives and anionic surfactants such as sodium salts of fatty acids and their esters, and compounds which react exothermically with the temperature responsive substances.

[0058] The second layer could be liquid crystals comprising liquid crystal molecules, wherein the alignment of the liquid crystal molecules of the liquid crystal material changes based on different temperatures of different regions of the given body part. Liquid crystal materials which are highly sensitive to temperature changes are suitable for use. For example, the liquid crystal material may react to 0.1°C change in temperature.

[0059] The temperature-sensitive substance could be cholesteric liquid crystalline formulations that display colours indicative of a defined temperature range. Cholesteric liquid crystals contain cholesteric esters such as cholesteryl pelargonate, cholesteryl chloride, oleyl cholesteryl carbonate, and all have colour changing properties. For clarity, multiple, pre-defined cholesteric liquid crystalline formulations with different temperature and time dependent properties, capable of transitioning into a glass state can be employed to display a temperature-dependent colour range. Once a cholesteric liquid crystalline formulation has changed into a glass state and a colour is displayed, then the original colour cannot be restored without inducing the formulation to change back to a liquid state.Cholesteric liquid crystalline formulations can be employed that indicate when the maximum temperature (thermokinetic limit) of the given body part has been exceeded. The term thermokinetic limit refers to a function of temperature and time and relates to the highest temperature at which the cholesteric liquid crystalline formulations will decompose and change their physical state and thus display a colour within the temperaturesensitive indicator device. Each cholesteric liquid crystalline formulation will have its own maximum temperature, known as the glass-transition temperature range. Depending on the temperature threshold of each of the cholesteric liquid crystalline formulation, the physical state of the liquid crystals will change to either a pseudo-irreversible or irreversible phase of the glass phase.

[0060] Multiple cholesteric liquid crystalline formulations may be employed to cover a pre-defined temperature range (from 25°C to 40°C for example, or a wider range), so as to be able to detect temperature changes across regions of the given body part. The cholesteric liquid crystalline formulations employed will detect temperatures within 0.5°C of a defined range. This colour change of the cholesteric liquid crystalline formulations is irreversible by cooling which allows for the temperature detected by the indicator to be viewed at a later time. The formulation of the thermochromic liquid crystals will be configured to increase the time that the colour map is visible on the temperature pads following removal from the heat source.

[0061] The second layer can be an adapted thermometer where a change in temperature of a thermally responsive material or temperature responsive substance (for example solid solutions of halogenated nitrobenzenes, or an organic compound that is easy to manufacture and is able to change its physical state) within the thermometer device can be reversible or irreversible. The thermometer device will have one or more region which contains one or more temperature responsive substance. The outside carrier of the temperature responsive substanceis made from a heat conducting material (such as aluminium or alloys thereof, copper, silver, gold, stainless steel or other heat-conductive materials) to allow rapid heat transfer from the area of the given body part to the temperature responsive substance and provide uniform temperature distribution throughout the thermometer when placed on a given area of the given body part. The outside carrier of the temperature responsive substance must have a relatively large surface area of contact with the region of the given body part and must be of a minimum thickness, but of a thickness that is adequate to preserve the structural integrity to allow rapid conduction of heat into the temperature responsive substance. The second layer can be a thermometer as outlined above which is disposable.

[0062] The at least one temperature-sensitive indicator may further comprise at least one of:

[0063] an organic dye selected from methyl violet, dibenzyl succinate, phenyl salicate and dibenzyl;

[0064] a surfactant selected from cationic surfactants including fatty acid nitrogen derivatives, non-ionic surfactants including polyethyleneoxy derivatives, and anionic surfactants including sodium salts of fatty acids and their esters; and

[0065] exothermic compounds.

[0066] Furthermore, the sensor device comprises a third layer covering the second layer. The term "third layer" as used herein refers to a plastic film that lines the thermochromic side of the second layer. The third layer typically protects the second layer from environmental and mechanical impacts to maintain the integrity of the second layer.

[0067] Moreover, the sensor device is configured to determine a differential temperature of different regions of the given body part, when at least partially in contact with the different regions of the given body part for a predefined time period. The term "differential temperature" as usedherein refers to a difference in temperature of a region of one body part that is different from the temperature of another region of the same body part. In this regard, when the given body part exhibits an abnormality or is diseased, the sensor device will detect a temperature that is higher in the abnormal / diseased region compared to a region of the given body part that does not have an abnormality or disease. The reading will be indicated by colour and digitally processed to provide an accurate result. It is advised that the sensor device is not used when the body temperature may be naturally elevated, for example following exercise or sunbathing.

[0068] A technical effect of determining temperatures of the aforementioned body parts is that body parts show a difference in temperature when the user suffers from disease, and the at least one sensor device can be used in a non-invasive manner for early-stage detection of any disease.

[0069] The sensor device is a wireless device and comprises a thermochromic substance that contains state-changing substances that emit a colour corresponding to a particular temperature. Wherein the given body part is the testicle this will be a lower temperature range.

[0070] The at least one sensor device can be in contact with the body part of the user for a predefined time period. In an instance, when the body part is the at least one testicle, the predefined time period may lie in a range of 5 minutes to 30 minutes. For example, the predefined time period is 15 minutes.

[0071] In this regard, the sensor device is reusable and is not disposable. The sensor device can withstand mild soap solutions) and medical grade detergents, thus the sensor device can be easily cleaned and re-used. The at least one temperature-sensitive layer may be sensitive for a temperature range from 25-40°C. Optionally, the at least one temperature-sensitive layer is sensitive for a temperature range from 25°C, 30°C, 35°C or 39°C up to 30°C, 35°C, 39°C or 40°C.The sensor device further may further comprise a fourth layer provided on the second side of the first layer, wherein the fourth layer comprises a unique identifier. The fourth layer typically refers to an identification layer that comprises a unique identifier such as an RFID, a QR code, etc., that can be associated with a device in repeated use for a specific user. It may be appreciated that the user may be registered with a given unique identifier for future uses of the device to maintain, for example, in a database, the temperature data of the user to identify the progression of a medical condition being studied.

[0072] The sensor device may further comprise:

[0073] a fifth layer arranged on the third layer, wherein the fifth layer is arranged to contact the different regions of the body; and

[0074] a sixth layer arranged on the second side of the first layer, wherein the sixth layer is at least partially transparent to enable imaging of:

[0075] the second layer through the second side of the first layer; and

[0076] the unique identifier of the fourth layer.

[0077] Herein, the term "fifth layer" refers to a contact layer that contacts the body part. The contact layer is typically biocompatible to ensure no allergies or discomfort to the body part contacted thereby. The contact layer may have a peelable outer layer that protects the contact layer from contacting surfaces for which the sensor device is not intended for use (such as the body parts other than the given body part, packaging, storage aids and any non-human organisms) and to prevent debris (for example air borne components such as dust and fibres and non-visible and microscopic entities such as bacteria and viruses) sticking to the surface when not in use.

[0078] The surface in contact with the given body part may have a non-adhesive, but non-slip outer layer on the soft outer layer of the soft foam pad to allow for secure and direct contact with the given body part outer skin layer. The non-adhesive, but non-slip outer layer may be rubber or a PVCfoam. The non-adhesive, but non-slip outer layer may be cleaned with a water and soap solution or medical grade detergent after use and will remain adhesive to allow for re-use.

[0079] It may be appreciated that the non-adhesive contact layer may have a peelable layer that protects the adhesive or the non-adhesive layer from sticking to surfaces for which the device is not intended for use and to prevent debris from sticking to the surface thereof when not in use.

[0080] The present disclosure also relates to the system as described above. Various embodiments and variants disclosed above, with respect to the aforementioned sensor device, apply mutatis mutandis to the system. The term "at least one camera" as used herein refers to an electronic device that is used to capture an image of the second layer. Optionally, the camera could be a Red-Green-Blue (RGB) camera or a grayscale camera. The at least one image (namely, one or more images) may be captured within a given time period which may be between 0-15 minutes. The given time period is determined based upon the temperaturesensitive material used in the sensor device. It will be appreciated that the at least one camera, communicably coupled to the at least one processor, that is able to execute a software application, could be embodied through a singular device, for example, a user's camera smartphone and the like.

[0081] The term "at least one processor" as used herein refers to a computational element that is operable to respond to and process instructions. The at least one processor, in operation, implements the method for determining the temperatures in the body part. Furthermore, the term "processor" may refer to one or more individual processors, processing devices and various elements associated with a processing device that may be shared by other processing devices. Such processors, processing devices and elements may be arranged in variousarchitectures for responding to and executing the steps of the temperature measurement method.

[0082] The processor implements the method for determining temperatures of different regions of a given body part. The processor identifies, the image segment representing the temperature-sensitive element and analyses it for variations in colour (i.e., a colour gradient). The processor identifies the image segment by employing an image processing algorithm. A given image processing algorithm could be an object identification algorithm or a feature detection algorithm. Post image segment identification, the processor is configured to recognize pixel values of pixels in the image segment. The colour information may be indicative of the colour gradient, which may be predefined and calibrated for differences in temperature of the given body part. Calibration can depend on the temperature-sensitive material or the thickness of the first layer. The colour information may be expressed as Red-Green-Blue (RGB) colour component values, grayscale values, or similar.

[0083] The processor is communicably coupled to the camera and could receive the image from the camera as a video, image or live stream. Preferably, the processor is communicatively coupled to the camera via a communication network. The communication network may be wired, wireless, or a combination thereof. The communication network could be an individual network or a combination of multiple networks. Examples of the communication network may include, but are not limited to, the Internet, a local network (such as, a TCP / IP-based network, an Ethernetbased local area network, an Ethernet-based personal area network, a Wi-Fi network, and the like), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), a telecommunication network, and a short-range radio network (such as Bluetooth®).

[0084] The temperature-sensitive element displays a colour upon contact with the given body part. The camera takes an image and feeds this to theprocessing unit to assign a temperature measurement to the colours displayed across said region.

[0085] The processor is configured to execute a software application for implementing the processing task through a singular device, such as the user's smartphone. The software application could be a single software application or multiple software applications. The software application may be implemented as an application for a mobile device such as, but not limited to, a smartphone. The software application reads and interprets results from the image taken by the camera in the sensor device. The image captured has pixels of varying pixel values. Such interpretation may be made via the comparison of the value (i.e., the colour) of a particular pixel or groups of pixels in the image with the expected pixel value (i.e., colour) that represents the temperature of the given body part. Such interpretation can be made by mapping each pixel of the image to identify its value, and based on the calibration of the temperature-sensitive material, the corresponding temperature of a particular pixel value is retrieved by virtue of the corresponding colour. The temperature which corresponds to the pixel value is assigned, creating a map of temperature distribution of the given body part in contact with the temperature sensitive indicator.

[0086] The software identifies lower and higher temperatures boundaries within a region by reading the corresponding pixel values within a given range. The temperature threshold value could lie in a range of 35°C to 38°C. For example, values with a temperature difference lower than a fraction of a degree Celsius, but not including 0°C (for example, 0.25°C, 0.5°C, 0.75°C), or values up to but not including 2°C (for example 1.25, 1.5, 1.75) may be considered lower and higher temperature boundaries within the same region. This depends on a previous calibration of the software. Such calibration may be added as a strip adhered to the sensor device (for example adhered by glue) or directly printed onto the device (for example at an edge). Once the different temperature thresholds of theregions of the given body part are established, the software can indicate whether a region within the given body part is of a higher temperature, and therefore is an indication of a potential anomaly. For example, this may be a region of a relatively higher concentration of pixels in a colour map (i.e., temperature map) with a relative temperature difference from neighbouring regions of 1°C or 1.5°C.

[0087] The at least one processor may be further configured to:

[0088] determine whether a temperature of said region exceeds a predefined temperature threshold value for each region amongst the different regions of the given body part; and

[0089] generate a thermal map of the given body part based on the temperature profile of the given body part, wherein the thermal map indicates any region whose temperature exceeds the predefined temperature threshold value.

[0090] Herein, the term "differential temperature profile" refers to a detailed analysis of temperature variations across different regions or points within that specific body part. This kind of analysis is often conducted using thermal imaging technology or other temperature-sensing devices. The term "thermal map" is a representation of the temperature distribution over a specific area, herein one or more regions of a given body part. The thermal map could represent the temperature profile of different regions of the given body part. The thermal map could be a colour map or a grayscale map. A technical benefit of a thermal map is that the results generated by the sensor device are presented in a form, which can be accurately read and understood. Such maps are created using thermal imaging technology, which detects infrared radiation emitted by objects based on their temperature. Typically, the thermal maps are generated by using devices such as thermal cameras or infrared sensors, i.e., the devices that detect the infrared radiation emitted by surfaces and convert it into temperature data. The temperature data collected is then translated into a visual representation, often using acolour scale. Warmer temperatures are typically represented by warmer colours (such as red and yellow), while cooler temperatures are represented by cooler colours (such as blue and green). Beneficially, in medical imaging, identifying abnormal temperature patterns in the human body aids in associating the regions with abnormal temperature patterns with a potential medical condition.

[0091] The predefined temperature threshold value in terms of body temperature is a reference point or limit beyond which a person's body temperature is considered abnormal. Body temperature is a critical physiological parameter, and deviations from the normal range can indicate various health conditions, including fever or hypothermia. The threshold values can vary depending on the method of temperature measurement (e.g., oral, rectal, tympanic, or forehead), the age of the individual, and other factors.

[0092] Notably, the normal temperature of testicles, like other parts of the body, can vary, and it's typically slightly lower than the core body temperature. Typically, the normal temperature of the testicles is around 34.4°C to 35.6°C. However, if the testicles are exposed to conditions that increase or decrease the overall body temperature, such as in a hot environment or during illness, the temperature of the testicles may also be affected. In cases of fever or illness, the body's core temperature rises, and this increase in temperature can affect the testicles as well. Conditions affecting the testicles, such as infections or inflammation, may result in symptoms such as pain, swelling, or changes in temperature, and prompt medical attention is advisable in such cases. Moreover, certain factors (including exercise and the time of day) can influence body temperature. In this regard, the processor may also be further configured to determine whether a temperature of the given region of the given body part exceeds the predefined temperature threshold value amongst the different regions of the given body part and generate the thermal map of the givenbody part. The thermal map may indicate any region whose temperature exceeds the predefined temperature threshold value. When the temperature of said region exceeds a predefined temperature threshold value, this could indicate an abnormality.

[0093] The system may further comprise at least one user device communicably coupled to the at least one processor, wherein the at least one processor is further configured to send, to the at least one user device, at least one of: the temperatures of different regions of the given body part and a thermal map of the given body part for presentation on the at least one user device. The at least one user device has a display. In this regard, a user interface (III) is rendered on the display of the user device, such that the user can easily and accurately view the results. Examples of a given user device include, but are not limited to, a smartphone, a smartwatch, a tablet computer, a laptop computer, a desktop computer, an infotainment device, and a personal digital assistant. The processor may send the temperatures of the different regions of the given body part to the user's device. On the III rendered on the display, the temperatures of the different regions of the given body part may be visually represented in the form of a table, a histogram, a schematic and / or a heat map. Further, the at least one processor sends the thermal map and the temperatures measured by the sensor device to the at least one user device.

[0094] The sensor device is to be used according to certain instructions for enabling accurate measurements. These instructions relate to the removal of the packaging, the required operating temperature, the manner in which the sensor device is to be placed on the given body part, how to hold the sensor device when in use, the optimal body posture of the user when using the sensor device, and how to remove the sensor device after the use.A digital display on the sensor device may be configured to display the device operational instructions. The range of thermal sensitivity of the temperature-sensitive material may affect the operating temperature range of the sensor device. The operating temperature could lie in the operating temperature range of 25°C to 41°C.

[0095] To achieve a predefined efficiency of the sensor device, the user may be instructed to store the sensor device in a refrigerator, at a room temperature below 26°C and away from any source of heat including heat generating lights in order to achieve an optimum performance by the temperature-sensitive material. The predefined temperature range for storing the sensor device is stored in the memory of the sensor device, such that a performance of the sensor device does not deteriorate. The predefined temperature range could lie within a range of 4°C to 12°C. The at least one camera may be configured to capture at least one identification image representing a unique identifier of a fourth layer of the at least one sensor, wherein the at least one processor is configured to:

[0096] identify the unique identifier in the at least one identification image; associate the temperatures of different regions of the given body part that are determined to the unique identifier; and

[0097] perform one of: block future interpretation of sensed temperatures from the at least one sensor device, permit future interpretation of sensed temperatures from the at least one sensor device upon successful reuse actions being implemented.

[0098] The sensor device may comprise a unique identifier. The camera is configured to capture an image representing the unique identifier, provided in the fourth layer of the sensor device, wherein the processor may be configured to identify the unique identifier in the image, associate the temperatures of different regions of the given body part that are assigned to the unique identifier.As an example, the unique identifier is identifiable by the camera through the first layer of the sensor device. The unique identifier could be any of a quick response (QR) code, an alphanumeric code, a Radio Frequency Identification (RFID) marker, a noise pattern, and the like. The at least one camera captures the at least one identification image. The at least one identification image includes the unique identifier. The at least one identification image is received by the at least one processor via the communication network. The at least one processor identifies the at least one identification image using at least one feature recognition algorithm. Such feature recognition algorithms are well-known in the art.

[0099] Further, the at least one processor associates the unique identifier on the at least one sensor device with the temperatures of different regions of the testicle determined using the at least one sensor device. The at least one processor also records uses of the unique identifier which is essential to determine uses of the at least one sensor device. The unique identifier could also be used to ensure a condition of the at least one sensor device prior to use. For example, the unique identifier may be used to ensure the at least one device is working properly.

[0100] Furthermore, the at least one processor may be configured to block future interpretation of the sensed temperatures from the at least one sensor device. The at least one processor can only interpret temperatures of different regions of the body part which are associated with the unique identifier. Further, the at least one processor permits future interpretation of sensed temperatures from the at least one sensor device upon successful reuse actions being performed. The reuse actions could be performed by the user, for example, after a reuse action of replacing the unique identifier with another one. The at least one processor may associate the sensed data with a new unique identifier and allow interpretation of the temperatures. The at least one processor may allow reuse of the at least one sensor device only after a reuse action of apredefined check or confirmations is / are made by the user. In this regard, the at least one processor could prompt the user to provide any input value in order to enable another use of the at least one sensor device. As an example, the input value may be an ambient temperature of a place where the at least one sensor is being used. In case, the ambient temperature is less than 25°C, reuse may be permitted owing to fewer chances of sweating. As another example, the input value may be the sensed temperature of a previous test. In case, the previous temperatures of any region of the body part are not above the temperature threshold value, the reuse may be allowed, as the at least one temperature-sensitive element will not impact the accuracy of future detection of temperatures. The technical benefit of this is that the unique identifier on the at least one sensor device is associated with the measurement obtained using the at least one sensor device. The association of the measurements with the unique identifier prevents future interpretation using the at least one sensor device, thereby solving the problem of multiple uses of conventional systems. The multiple uses might significantly decrease the accuracy of the results. Therefore, the at least one sensor device is restricted to single-use only until certain checks are provided. Owing to the above, the accuracy of the system is significantly improved.

[0101] The at least one processor is further configured to process the at least one identification image to:

[0102] determine at least one usage parameter associated with the use of the at least one sensor device, wherein the at least one usage parameter is selected from at least one of: a given body part for use, a total number of uses, a number of current uses, a remaining number of uses, a predefined temperature range for storing the at least one sensor device when not in use, a time period of use; and

[0103] associate the at least one usage parameter to the unique identifier.In this regard, the at least one identification image is used to know details regarding the at least one sensor device prior to usage. A technical effect of determining the at least one usage parameter is that a detailed information about the at least one sensor device is provided to the user, so that the user can make an informed decision regarding usage of the at least one sensor device. The at least one identification image is processed in real time or in near-real time. Herein, the at least one sensor device may be designed based on the body part with which said at least one sensor device is to be in contact. Hence, the at least one identification image is processed to extract information regarding the body part for which the at least one sensor device is to be used for, and provide said information to the user regarding the body part in a form of a text, a code, a number, an alphanumeric text, or an image.

[0104] Upon processing the at least one identification image, historical data is provided to the user in the form of the number of times the at least one sensor device has been used, and the total number of times the at least one sensor device can be used. Herein, the number of times, the remaining number of times, and the total number of times are finite numeric values, wherein the total number of times is used as a reference value. The remaining number of times is a difference between the number of times the at least one sensor device has been used and the total number of times the at least one sensor device can be used. For example, the total number of times the at least one sensor device may be used for is 4 times. The number of times the at least one sensor device has already been used for may be 3 times. Hence, the remaining number of times for the future use of the at least one sensor device is 1 time.

[0105] Additionally, upon processing the at least one identification image, the predefined temperature range for storing the at least one sensor device when not in use is provided such that a performance of the at least one sensor device does not deteriorate. The predefined temperature rangecould lie in a range of 4°C to 12°C. The predefined temperature range lies in a range of 4°C to 6°C, 4°C to 8°C, 4°C to 10°C, 4°C to 12°C, 6°C to 8°C, 6°C to 10°C, 6°C to 12°C, 8°C to 10°C, 8°C to 12°C, 10°C to 12°C, or similar. Additionally, the term "time period" refers to a period of time after which the at least one sensor device will expire, i.e., an accuracy with which the at least one sensor device determines the temperature of the body part, reduces. Herein, the time period may be a month, 2 months, 4 months, 8 months, 12 months, 24 months, and similar.

[0106] The at least one processor may associate the at least one usage parameter by way of connecting or linking to the unique identifier, wherein the at least one processor correlated the at least one usage parameter to a corresponding unique identifier. The at least one processor is further configured to send to the at least one user device, the at least one usage parameter, for presentation on the at least one user device.

[0107] The at least one camera may be configured to capture at least one given body part image of the user, wherein the at least one processor is further configured to:

[0108] identify features of the given body part that are represented in the at least one body image;

[0109] digitally superimpose at least one virtual object on the at least one given body part image for enabling correct placement of the at least one sensor device on the given body part; and

[0110] send the at least one given body part image having the at least one virtual object superimposed thereon to the at least one user device for display thereat.

[0111] In this regard, the features of the given body part could be edges, shapes, sizes, colours of different regions, or the like. The at least one processor may be configured to identify the features of the body part that arerepresented in the at least one body image using at least one feature detection algorithm. A given feature detection algorithm may be at least one of: an edge-detection algorithm, a corner-detection algorithm, a blob-detection algorithm, a feature descriptor algorithm. Further, the at least one processor may be configured to digitally superimpose the virtual object on the different regions of the at least one body image, as required. The virtual object is a computer-generated object used to indicate different features of the body part that are represented in the at least one body image. The virtual object could be a geometric shape, an arrow, a pattern, or similar, that enables correct placement of the at least one sensor device on the body part. The at least one body image superimposed with the virtual object is an augmented reality image. Further, the at least one processor sends the at least one augmented reality image to the user device in order to be displayed. The technical benefit of this is that the augmented reality image is utilized to provide accurate positioning of the at least one sensor device on the body part thereby improving the efficiency and accuracy of the results.

[0112] The at least one processor may be configured to: for different regions of a given body part, compare a first temperature of a first region with a second temperature of a second region to determine a temperature difference therebetween.

[0113] The at least one processor may be further configured to determine whether the temperature difference exceeds a predefined difference. When for the given region of the body part, the temperature difference exceeds the predefined difference, the at least one processor may be configured to indicate a possibility of an abnormality being present. The predefined difference could lie in a range of 0.5°C to 2.5°C. The predefined difference could lie in a range of 0.5°C to 1°C, 0.5°C to 1.5°C, 0.5°C to 2°C, 0.75°C to 1.5°C, 0.75°C to 2°C, 0.75°C to 2.5°C, 1°C to 1.5°C, 1°C to 2°C, 1.5°C to 2°C, 1.5°C to 2.5°C or similar. In an example,the temperature difference between two regions of each of the body part may be equal to or greater than 2°C, which may relate to a condition of abnormality in the body part. The technical benefit of this is that the at least one sensor device is able to detect the abnormality accurately. It will be appreciated that the system can be efficiently used by users of all ages. The system can use the software application to measure the different temperatures of regions of the given body part. The system can transmit the temperature from the given body part region to the software application. The software application significantly increases the accuracy and consistency of measurements obtained using the sensor device and provides an interactive and / or easy to use platform to view results. A mobile phone equipped with a camera can be used to read the temperatures of different regions of the given body part by taking a picture of the second layer. A mobile phone will also allow the user to view the temperatures determined upon processing. The processor of the user's device may be employed for the processing. In such a case, a single user's device may be beneficially used for implementing the camera as well as the processor of the system. The technical advantage of this is that the results obtained by the system can be efficiently captured and viewed using the user's device making the system of the present disclosure very compact and easy to use.

[0114] The processor of the sensor device can associate the unique identifiers with the temperatures of different regions of the given body part. The processor can also record the uses of the unique identifier. The unique identifier could also be used to ensure a condition of the sensor device prior to use. The processor can only interpret temperatures of different regions of the given body part which are associated with the unique identifier. Further, the processor permits future interpretation of sensed temperatures upon successful reuse actions being performed. The reuse actions could be performed by the user. The processor may associatedata with a new unique identifier and allow interpretation of the temperatures. The processor may allow the reuse of the sensor device only after a reuse action of a predefined check or confirmations is / are made by the user. The unique identifier on the sensor device is associated with the measurement obtained using the sensor device.
