More specifically, the present invention relates to a temperature sensor, a wearable device including a temperature sensor, and a method for measuring deep body temperature using a temperature sensor, which can be applied to a wearable device manufactured to be attached to the body in a band or patch type, and can efficiently measure the deep body temperature taking into account the ambient temperature. [Background technology]

[0002] In recent years, with the spread of infectious diseases and the importance of managing personal health being emphasized, various types of healthcare related products have been developed.

[0003] In particular, with the development of wearable healthcare products, the applications of these products are increasing, such as obtaining and analyzing various information on users' biosignals, such as electrocardiograms, oxygen saturation, body temperature, pulse, blood pressure, and activity levels, to provide personalized health management monitoring or to use the information as a database in providing medical services.

[0004] For such wearable healthcare products, the most important thing is to accurately measure the user's vital signs, and among the vital signs, the most important thing is information regarding the user's body temperature, particularly core body temperature.

[0005] Regarding the measurement of such deep body temperature, Korean Patent Publication No. 10-2020-0061579 and No. 10-2020-0061580 disclose technology relating to a deep body temperature measuring device that is inserted into the user's ear to measure deep body temperature. However, due to its complex structure, it is not easy to manufacture and difficult to implement in a wearable device, resulting in problems such as reduced usability for users.

[0006] Related prior art includes Korean Patent Publication No. 10-2020-0061579 and Korean Patent Publication No. 10-2020-0061580. Summary of the Invention [Problem to be solved by the invention]

[0007] The technical problem of the present invention has been solved by taking the above into consideration, and the object of the present invention is to provide a temperature sensor that can be applied to a wearable device that is manufactured to be able to be attached to the body in the form of a band or patch, and that can efficiently measure deep body temperature taking into account the ambient temperature.

[0008] Another object of the present invention is to provide a wearable device including the temperature sensor.

[0009] Furthermore, another object of the present invention is to provide a method for measuring deep temperature using the above-mentioned temperature sensor. [Means for solving the problem]

[0010] A temperature sensor according to an embodiment for achieving the above-mentioned object of the present invention includes a sensing unit and a substrate. The sensing unit has a base, a measuring unit mounted on the base and contacting a subject's body to sense temperature, and a cover for covering the measuring unit. The substrate has the sensing unit mounted thereon. In this case, a plurality of slits are formed on the substrate along the periphery of a first region on which the sensing unit is mounted.

[0011] Furthermore, the sensing unit has a terminal portion that extends from the base portion to the opposite side of the measurement portion, passes through the substrate portion, and is electrically connected to the substrate portion.

[0012] The cover body covers all of the measuring part except for the part facing the body, and the measuring part exposed to the part facing the body comes into contact with the body and senses the temperature.

[0013] The lid body includes a measurement sensor for measuring ambient temperature data.

[0014] The slit is spaced a predetermined distance from the first region, and each of the slits is spaced a predetermined distance from each other.

[0015] The separation distance between the slits is less than the length along which each of the slits is formed.

[0016] A wearable device according to another embodiment for achieving the above-mentioned object of the present invention includes the temperature sensor, a biosignal measurement unit, a display unit, and a case. The biosignal measurement unit measures other biosignals of a subject. The display unit displays the measurement results of the temperature sensor and the biosignal measurement unit to the outside. The temperature sensor, the biosignal measurement unit, and the display unit are located inside the case.

[0017] The measuring portion of the temperature sensor is exposed to the outside of the case and comes into contact with the subject's body.

[0018] A wearable device according to another embodiment for achieving the above-mentioned object of the present invention includes the temperature sensor, a biosignal measuring module, a communication module, and a connection unit. The biosignal measuring module measures other biosignals of a subject. The communication module is located on the opposite side of the biosignal measuring module and communicates with the outside. The connection unit connects the biosignal measuring module and the communication module to each other. The temperature sensor is located inside the biosignal measuring module or the connection unit.

[0019] The connecting portion is a flexible structure, and the measurement portion of the temperature sensor is exposed to the outside of the connecting portion or to the outside of the biosignal measurement module and comes into contact with the subject's body.

[0020] It further includes a first electrode attached to the bottom of the biosignal measurement module and in contact with the subject's body, and a second electrode attached to the bottom of the communication module and in contact with the subject's body.

[0021] Another embodiment of a deep temperature measurement method for achieving the above-mentioned object of the present invention measures deep temperature using the temperature sensor, and includes a step of acquiring ambient temperature data, a step of acquiring deep body temperature data using the temperature sensor, and a step of correcting the deep body temperature data based on the ambient temperature data.

[0022] In the step of correcting the deep body temperature data, the ambient temperature data is compared with the deep body temperature data. If a first temperature condition is satisfied, the deep body temperature data is not corrected and is regarded as the deep temperature of the subject. If a second temperature condition is satisfied, the deep body temperature data is corrected to derive the deep temperature of the subject.

[0023] The first temperature condition is that the ambient temperature data is between 24°C and 26°C, and the second temperature condition is that the ambient temperature data is less than 24°C or greater than 26°C.

[0024] When correcting the deep body temperature data,

[0025] T C =T O +T A ×C W Formula (1)

[0026] Here, T C is the corrected core temperature, T O is the measured core body temperature, T A is the measured ambient temperature, C W is a correction coefficient, and the deep body temperature data is corrected using the formula (1). Effect of the Invention

[0027] According to the present invention, in order for the measurement part of the sensing unit to operate, the measurement part must be mounted on a substrate part, but heat generated from various elements is provided to the measurement part through the substrate part, which may actually result in low accuracy of the subject's temperature sensing results.

[0028] In this embodiment, a plurality of slits are formed on the substrate to isolate the first area in which the sensing unit is mounted, thereby minimizing heat transfer by the substrate, thereby improving the accuracy of the measurement results by the measurement unit.

[0029] In this case, only the portion of the measuring part facing the body is exposed, and the other portion is covered by the lid, so that more accurate sensing of body temperature can be achieved.

[0030] Furthermore, the temperature sensor is applied to a band-type or patch-type wearable device, and particularly when applied to a patch-type wearable device, the temperature sensor is mounted on a connecting part which is a flexible structure in order to improve contact with the subject's body.

[0031] Furthermore, in the case of wearable devices, various types of physical information can be obtained in addition to temperature, i.e., body temperature information, and the acquisition of biological information can be performed using electrodes that come into contact with the body.

[0032] In particular, when measuring deep body temperature, in order to minimize the inaccuracy of the measurement results due to the ambient temperature, the measured deep body temperature is corrected taking into account the ambient temperature, thereby enabling a more accurate deep body temperature to be derived.

[0044] The present invention can be modified in various ways and can have various forms, and the embodiments will be described in detail in the present specification.

[0048] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0049] 1a and 1b are a cross-sectional view and a plan view showing a temperature sensor according to one embodiment of the present invention.

[0050] As shown in FIGS. 1 a and 1 b , the temperature sensor 1 according to this embodiment includes a sensing unit 10 and a substrate portion 20 .

[0051] The sensing unit 10 includes a measurement section 11 , a cover section 12 , a base section 13 , and a terminal section 14 , and is mounted on the substrate section 20 .

[0052] Although not shown, the substrate unit 20 can be mounted with various elements in addition to the sensing unit 10, and electrical wiring can be formed between the sensing unit 10 and the elements.

[0053] In this case, the substrate unit 20 is, for example, a printed circuit board (PCB) or a flexible printed circuit board (FPCB).

[0054] The base portion 13 is located on the substrate portion 20, and the terminal portion 14 is extended from one side, for example, the lower side, of the base portion 13.

[0055] The terminal portion 14 passes through a predetermined opening formed on the substrate portion 20 and is electrically connected to the substrate portion 20 .

[0056] In this case, the number of the terminal parts 14 connected to the substrate part 20 is not limited, and is four as shown in FIG. 1b.

[0057] On the other hand, in the base portion 13, the measuring portion 11 is located on the side opposite to the side on which the terminal portion 14 extends, for example, on the upper side.

[0058] The measuring unit 11 is a sensor that comes into direct contact with the subject's body to measure the body temperature, that is, the body temperature. As long as it is sufficient to measure the body temperature, the type of sensor is not limited.

[0059] On the other hand, the body temperature measured by the measuring unit 11 is not the body surface temperature but the deep body temperature, and therefore the measuring unit 11 is a sensor capable of measuring the deep temperature.

[0060] In this case, as shown in FIG. 1a, only the top surface of the measuring unit 11 is exposed to the outside, and the other side surfaces are all covered by the lid unit 12.

[0061] That is, the cover body 12 covers the measurement unit 11 in a capsule-like manner, and only the exposed upper surface of the measurement unit 11 comes into direct contact with the subject's body.

[0062] In this case, the cover body 12 may be made of a heat insulating material.

[0063] As described above, the measurement unit 11 is covered by the cover unit 12 except for the portion that comes into contact with the subject's body, so that the influence of heat transferred from the outside can be minimized and the subject's body temperature can be measured more accurately.

[0064] Meanwhile, the cover body 12 includes a measurement sensor (not shown), and ambient temperature data can be obtained by the measurement sensor of the cover body 12. That is, in addition to measuring the deep body temperature by contacting the subject's body, ambient temperature data can also be obtained at the same time.

[0065] Meanwhile, in this embodiment, as shown in FIG. 1b, the substrate portion 20 has a plurality of slits 21 formed around a first area (A) in which the sensing unit 10 including the base portion 13 is mounted.

[0066] The slit 21 is an opening formed through the substrate part 20, and as the slit 21 is formed through the substrate part 20, the sensing unit 10 is positioned on the substrate part 20 in a so-called isolated state.

[0067] In this case, when the base portion 13 of the sensing unit 10 is formed in a circular shape, the slits 21 are formed in plurality along the periphery of the circular first region (A), and each slit 21 is formed at a certain distance from the first region (A).

[0068] Each of the slits 21 is also formed with a predetermined interval, that is, a gap portion 22, between adjacent slits.

[0069] For example, as shown in the figure, if four slits 21 are formed, each of the slits 21 is a circumferential slit that forms approximately 90 degrees, and as a whole, forms a circular slit that covers the periphery of the first region (A), and the gap portions 22 are formed at every 90 degree position, having a structure that is spaced apart from each other.

[0070] The sensing unit 10 must be electrically connected to other elements on the substrate 20 since it must be powered by the substrate 20 or controlled through a predetermined electrical signal.

[0071] In this embodiment, electrical connection for the operation of the sensing unit 10 is maintained through the gap portion 22, and the peripheral area of ​​the sensing unit 10 except for the minimum configuration for the electrical connection is formed entirely with open slits 21.

[0072] Generally, in the case of the substrate part 20, various elements are mounted and heat generated from the elements may be transferred, so that the heat transferred from the substrate part 20 is also transferred to the sensing unit 10. Thus, the sensing result of the sensing unit 10 is changed by the heat transferred from the substrate part 20 in addition to the heat actually transferred from the body.

[0073] In addition, by forming the slits 21 around the sensing unit 10, it is possible to block the heat transferred from the substrate portion 20, thereby minimizing the inclusion of factors other than the heat transferred from the body in the heat measured by the sensing unit 10.

[0074] Thus, the accuracy of the body temperature measurement results obtained by the temperature sensor 1 according to this embodiment is further improved.

[0075] 2a, 2b and 2c are a perspective view, a bottom view and a cross-sectional view showing a band-type wearable device including the temperature sensor in FIG. 1a.

[0076] As shown in Figures 2a to 2c, the band-type wearable device 30 (hereinafter also referred to as the wearable device) in this embodiment includes, in addition to the temperature sensor 1 described in Figures 1a and 1b, a case 35, a band unit 36, a display unit 31, a power supply unit 32, and a biosignal measurement unit 33.

[0077] The temperature sensor 1 is the same as that described above, and therefore a duplicated description of the detailed configuration will be omitted.

[0078] As shown in the figure, the case 35 is composed of a front portion on which the display unit 31 is formed, and a rear portion on which the temperature sensor 1, the power supply unit 32, and the biosignal measurement unit 33 are formed, and its shape is not limited.

[0079] In this case, the rear surface on which the temperature sensor 1, the power supply unit 32, and the biosignal measuring unit 33 are formed is the surface that directly contacts the subject's body, such as the wrist, and thus the front surface faces the outside, and the user can check the results measured through the temperature sensor 1 and the biosignal measuring unit 33 by using the display unit 31 formed on the front surface.

[0080] The band portion 36 is connected to both sides of the case 35 and fixes the case 35 to the subject's wrist.

[0081] As described above, the wearable device 30 can be manufactured in a band shape and fixed to the subject's wrist or the like.

[0082] The power supply unit 32 provides power to the temperature sensor 1 , the vital sign measurement unit 33 , and the display unit 31 .

[0083] In this case, as shown in the figure, the temperature sensor 1 is fixed to the case 35 so that the part of the measuring unit 11 exposed to the outside faces downward, thereby measuring the subject's body temperature, i.e., body temperature, through the exposed part.

[0084] On the other hand, the vital sign measuring section 33 can measure other vital information of the subject, except for the body temperature of the subject measured by the temperature sensor 1.

[0085] For example, the vital sign measuring unit 33 can measure the oxygen saturation, pulse, blood pressure, electrocardiogram, etc. of the subject, and in this case, the type and structure of the vital sign measuring unit 33 are not limited.

[0086] As described above, the temperature sensor 1 is provided in the band-type wearable device 30, and in particular, the exposed portion of the measuring unit 11 of the temperature sensor 1 is positioned so as to face the body, thereby making it possible to measure the temperature of the subject's body.

[0087] 3a and 3b are perspective and cross-sectional views showing a patch-type wearable device including the temperature sensor in FIG. 1a.

[0088] As shown in Figures 3a and 3b, the patch-type wearable device 40 (hereinafter also referred to as the wearable device) in this embodiment includes, in addition to the temperature sensor 1 described in Figures 1a and 1b, a biosignal measurement module 41, a communication module 43, a connecting portion 44, and first and second electrodes 45, 46.

[0089] In this case, the temperature sensor 1 is the same as that described above, so a duplicated description of the detailed configuration will be omitted.

[0090] As shown in the figure, the biosignal measuring module 41 is formed in a flat rectangular block structure, and a biosignal measuring section 42 is located inside.

[0091] In this case, the vital sign measurement unit 42 is substantially identical to the vital sign measurement unit 33 described in FIG. 2c.

[0092] Furthermore, although not shown, in addition to the biosignal measurement section 42, various elements capable of measuring biosignals may be provided in combination on the biosignal measurement module 41 to form a single module.

[0093] The communication module 43 is located on the opposite side to the vital sign measuring module 41 at a predetermined distance therefrom, and includes various communication elements therein for transmitting and receiving data.

[0094] Thus, through the communication module 43, information measured through the vital sign measuring module 41 and the temperature sensor 1 is provided to the outside.

[0095] The connection part 44 has one end connected to the biosignal measuring module 41 and the other end connected to the communication module 43, thereby connecting the biosignal measuring module 41 and the communication module 43 to each other.

[0096] In this case, the temperature sensor 1 is provided inside the connecting portion 44, and the temperature sensor 1 is fixed so that the portion of the measuring portion 11 that is exposed to the outside faces downward.

[0097] Thus, the measuring unit 11 is exposed on the lower surface of the connecting unit 44, and the lower surface of the connecting unit 44 comes into contact with the subject's body, so that the body temperature can be measured through the measuring unit 11.

[0098] In this case, the connecting portion 44 is formed of a flexible structure so that it can be easily bent or flexed, thereby allowing it to be positioned naturally anywhere on the subject's body, which has various surface shapes, to measure body temperature.

[0099] Alternatively, the temperature sensor 1 may be located adjacent to the biosignal measuring unit 42 inside the biosignal measuring module 41, not inside the connecting part 44. This can minimize damage caused by structural changes to the flexible structure of the connecting part 44 by positioning the temperature sensor 1 on the connecting part 44.

[0100] On the other hand, a first electrode 45 is attached to the underside of the biosignal measuring module 41, i.e., the side facing the subject's body, and a second electrode 46 is attached to the underside of the communication module 43, i.e., the side facing the subject's body.

[0101] The first electrode 45 and the second electrode 46 are electrodes for measuring biosignals and are attached so as to be in direct contact with the body, and the electrical signal to be measured is provided to the biosignal measuring section 42 of the biosignal measuring module 41.

[0102] Thus, the biosignal measuring section 42 can obtain various bioinformation of the subject based on the electrical signals provided from the electrodes 45 and 46.

[0103] In this case, the biological information to be acquired is information acquired through electrical signals such as an electrocardiogram, and further includes various biological information such as oxygen saturation, pulse, and blood pressure.

[0104] Meanwhile, the first and second electrodes 45, 46 are in the form of a patch that can be directly attached to the subject's body. As a result, the wearable device 40 in this embodiment is in the form of a patch that can be directly attached to a specific position on the subject's body, and can acquire various biological information as well as body temperature.

[0105] FIG. 4 is a flow chart showing a method for measuring deep temperature using the temperature sensor in FIG. 1a, and FIG. 5 is a flow chart showing the method for measuring deep temperature in FIG. 4 in more detail.

[0106] As shown in FIGS. 4 and 5, when measuring the deep temperature of a subject using the temperature sensor 1 described in FIGS. 1a and 1b, first, ambient temperature data is obtained (step S10).

[0107] In this case, although not separately described in Figures 1a and 1b, the temperature sensor 1 is provided with another temperature sensor for measuring the ambient temperature in addition to the measuring unit 11 that is in direct contact with the subject's body and measures the subject's body temperature, i.e., body temperature.

[0108] In this case, the temperature sensor is the measurement sensor included in the cover body portion 12 as described above, and this makes it possible to measure the ambient temperature.

[0109] Alternatively, such a temperature sensor may be provided as a separate element on the substrate portion 20 of the temperature sensor 1 described in Figures 1a and 1b, and alternatively, it may be provided as a separate element within the case 35 of the band-type wearable device 30 described in Figures 2a to 2c, or may be provided as a separate element within the biosignal measurement module 41 or the connection portion 44 of the patch-type wearable device 40 described in Figures 3a and 3b.

[0110] More specifically, in the step of acquiring the ambient temperature data (step S10), the amount of change in the ambient temperature per unit time is measured using another temperature sensor described above (step S11), and based on the amount of change in the ambient temperature thus measured, it is determined whether the ambient temperature is in a state of thermal equilibrium (step S12), and whether to measure the ambient temperature is determined.

[0111] Meanwhile, whether or not the thermal equilibrium state is reached can be determined through a separate control unit (not shown), and it is determined that the thermal equilibrium state is reached when the amount of change in the ambient temperature remains within a predetermined range for a predetermined period of time.

[0112] Thus, when it is determined that the ambient temperature is in a thermal equilibrium state (step S12), the ambient temperature (T A ) is measured (step S13).

[0113] Thereafter, deep body temperature data is obtained through the temperature sensor 1 (step S20).

[0114] More specifically, the temperature sensor 1 measures the temperature of the subject's body, i.e., the body temperature, through the measuring unit 11 that contacts the body, and the body temperature thus measured is referred to as the deep body temperature data (T O )

[0115] Thereafter, the core body temperature data is corrected based on the ambient temperature (step S30).

[0116] More specifically, the acquired ambient temperature (T A ) satisfies a predetermined condition (step S31), and the deep body temperature data is corrected based on the range of the ambient temperature (steps S32 and S33).

[0117] That is, the ambient temperature (T A ) is in the first temperature condition, i.e., 24°C to 26°C, the deep body temperature data (T O ) without applying any other correction to the acquired deep body temperature data (T O ) is used as is, and the corrected core body temperature (T C ) is considered.

[0118] In contrast, the ambient temperature (T A ) is in the second temperature condition, i.e., less than 24°C or greater than 26°C, the core body temperature data (T O ) is corrected using the following formula (1).

[0119] T C =T O +T A ×C W Formula (1)

[0120] Here, T C is the corrected core temperature, T O is the measured core body temperature, T A is the measured ambient temperature, C W is the correction factor.

[0121] On the other hand, the correction coefficient (C W ) is a coefficient preset by another look-up table, and can be preset, for example, as in Table 1.

[0122] That is, the correction coefficient (C W ) is the measured ambient temperature (T A ) based on the information, the coefficient is preset as follows, and by calculating the above formula (1), the final corrected deep body temperature data (T C ) can be obtained (step S32).

[0123] As described above, when measuring the body temperature through the temperature sensor 1, ambient temperature information can be obtained at the same time, and the measured deep body temperature can be corrected based on this to obtain more accurate deep body temperature information.

[0124] [Table 1] TIFF0007602635000001.tif21496

[0125] According to an embodiment of the present invention, in order for the measurement part of the sensing unit to operate, the measurement part must be mounted on a substrate, and heat generated from various elements is provided to the measurement part through the substrate, which may result in low accuracy of the temperature sensing results of the actual subject.

[0126] In this embodiment, a plurality of slits are formed on the substrate to isolate the first area in which the sensing unit is mounted, thereby minimizing heat transfer through the substrate and thereby improving the accuracy of the measurement results through the measurement unit.

[0127] In this case, only the portion of the measuring part facing the body is exposed, and the other portion is covered by the lid, so that more accurate sensing of body temperature can be achieved.

[0128] Furthermore, the temperature sensor is applicable to band-type or patch-type wearable devices, and particularly when applied to a patch-type wearable device, the temperature sensor is mounted on a connecting part which is a flexible structure in order to improve contact with the subject's body.

[0129] Furthermore, in the case of wearable devices, various types of physical information can be obtained in addition to temperature, i.e., body temperature information, and the acquisition of biological information can be performed using electrodes that come into contact with the body.

[0130] In particular, when measuring deep body temperature, in order to minimize the inaccuracy of the measurement results due to the surrounding environmental temperature, the measured deep body temperature is corrected taking into account the surrounding temperature, thereby enabling a more accurate deep body temperature to be derived.
