[0002] Recently, with the spread of infectious diseases and the emphasis on the importance of managing personal health, various types of healthcare-related products have been developed.

[0003] With the development of wearable healthcare products, their utilization is increasing. For example, they can acquire various users' biosignal information, such as electrocardiogram, oxygen saturation, temperature, pulse, blood pressure, and activity level, analyze and monitor this information, conduct patient-specific health management monitoring, or use this information as a database when providing medical services.

[0004] Among these wearable healthcare products, the most important aspect is the accurate measurement of the user's biosignals. Specifically, the most important biosignal is the user's body temperature, especially information about core body temperature.

[0005] Regarding the measurement of core body temperature, Korean Patent Application Publication No. 10-2020-0061579 or No. 10-2020-0061580 disclose technologies for core body temperature measurement devices that are inserted into the user's ear to measure core body temperature. However, in the prior art, the structure of such devices is complex, difficult to manufacture, and not easy to implement as wearable devices, resulting in problems such as reduced user usability.

[0006] As mentioned above, the relevant prior art is Korean Patent Application Publication No. 10-2020-0061579 and No. 10-2020-0061580. Summary of the Invention

[0007] An exemplary embodiment of the present invention provides a temperature sensor that can effectively measure the core temperature of the body taking into account the ambient temperature, and can be applied to wearable devices manufactured as strips or patches for easy attachment to the body.

[0008] An exemplary embodiment of the present invention also provides a wearable device including a temperature sensor.

[0009] An exemplary embodiment of the present invention also provides a core temperature measurement method using a temperature sensor.

[0010] According to one aspect of the invention, a temperature sensor includes a sensing unit and a substrate. The sensing unit includes: a base component; a measuring component mounted on the base component and configured to measure the temperature of a subject's body by contact with the subject's body; and a cover component configured to cover the measuring component. The sensing unit is mounted on the substrate. A plurality of slits are formed around a first region of the substrate, and the sensing unit is mounted at the first region of the substrate.

[0011] In an exemplary embodiment, the sensing unit may further include a terminal component that extends from the base component toward the opposite side of the measuring component and passes through the substrate for electrical connection with the substrate.

[0012] In an exemplary embodiment, the cover member may cover the entire measuring member except for the portion of the measuring member facing the subject's body, and the portion of the measuring member exposed to the subject's body may come into contact with the subject's body to measure the subject's body temperature.

[0013] In an exemplary embodiment, the cover component may include a measuring sensor configured to measure ambient temperature.

[0014] In an exemplary embodiment, the slits may be separated from the first region by a predetermined distance, and the slits may be separated from each other by a predetermined distance.

[0015] In an exemplary embodiment, the distance between adjacent slits may be less than the length of each slit in the slit.

[0016] According to another aspect of the invention, a wearable device includes a temperature sensor, a vital signs measurement component, a display component, and a housing. The vital signs measurement component is configured to measure vital signs of a subject's body, in addition to body temperature. The display component is configured to display the results of the temperature sensor and the vital signs measurement component. The housing receives the temperature sensor, the vital signs measurement component, and the display component.

[0017] In an exemplary embodiment, the measuring component of the temperature sensor may be exposed outside the housing to come into contact with the subject's body.

[0018] According to another aspect of the invention, a wearable device includes a temperature sensor, a vital signs measurement module, a communication module, and a connection component. The vital signs measurement module includes the vital signs measurement component, and the vital signs measurement component is configured to measure vital signs of the subject's body other than body temperature. The communication module is positioned opposite the vital signs measurement module and configured to communicate with an external source. The connection component is configured to connect the vital signs measurement module and the communication module. The temperature sensor is disposed within either the vital signs measurement module or the connection component.

[0019] In an exemplary embodiment, the connecting component may be a flexible structure, and the measuring component of the temperature sensor may be exposed outside the connecting component or outside the vital signs measuring module to make contact with the subject's body.

[0020] In an exemplary embodiment, the wearable device may further include: a first electrode attached to a lower portion of the vital signs measurement module for contact with the subject's body; and a second electrode attached to a lower portion of the communication component for contact with the subject's body.

[0021] According to another aspect of the present invention, in a core temperature measurement method using a temperature sensor, the ambient temperature is acquired. The core body temperature is acquired using a temperature sensor. The core body temperature is then corrected based on the ambient temperature.

[0022] In an exemplary embodiment, when calibrating core body temperature, the ambient temperature can be compared with the core body temperature. Then, when the ambient temperature meets a first temperature condition, the core body temperature may not be calibrated and is regarded as the core temperature of the subject's body. When the ambient temperature meets a second temperature condition, the core body temperature may be calibrated to obtain the core temperature of the subject's body.

[0023] In an exemplary embodiment, under the first temperature condition, the ambient temperature may be in the range between 24°C and 26°C, and under the second temperature condition, the ambient temperature may be lower than 24°C or higher than 26°C.

[0024] In an exemplary embodiment, the core body temperature can be corrected using the following equation (1).

[0025] T C =T O +T A ×C W [Equation 1]

[0026] Here, T c It can be the corrected core body temperature, T o It can be the core body temperature being measured, T. A It can be the measured ambient temperature, and C wIt can be a correction factor.

[0027] According to some exemplary embodiments of the present invention, the measuring component is mounted on the substrate to be operated, but the heat generated by various components may be provided to the measuring component through the substrate, so the measured body temperature of the subject may be inaccurate.

[0028] Therefore, in the present exemplary embodiment, a plurality of slits are formed in the substrate to isolate the first region in which the sensing unit is formed. Thus, heat transfer through the substrate can be minimized, and the measured temperature of the subject's body can be accurate.

[0029] Here, only a portion of the measuring component facing the subject's body is exposed, while the rest of the measuring component is covered, thus ensuring accurate measurement of the subject's body temperature.

[0030] In addition, temperature sensors can be applied to strip-type or patch-type wearable devices. When applied to patch-type wearable devices, the temperature sensor can be mounted on a connecting component with a flexible structure to increase adhesion to the subject's body.

[0031] In addition to body temperature, various vital signs can be obtained in wearable devices, and these vital signs can be obtained using electrodes that come into contact with the subject's body.

[0032] Here, in order to improve the accuracy of core body temperature measurement, ambient temperature is used to correct the core body temperature. Attached Figure Description

[0044] The invention is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0045] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to limit the invention. As used herein, the word “the” is intended to include plural forms unless the context clearly indicates otherwise.

[0046] It should also be understood that, when used in this specification, the term "comprising" specifies the presence of the stated features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or groups thereof.

[0047] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms (such as those defined in common dictionaries) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0048] The invention will be explained in detail below with reference to the accompanying drawings.

[0049] Figure 1A and Figure 1B These are cross-sectional views and plan views of a temperature sensor according to an exemplary embodiment of the present invention.

[0050] refer to Figure 1A and Figure 1B The temperature sensor 1 according to this example embodiment includes a sensing unit 10 and a substrate 20.

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

[0052] Although not shown in the figure, various components can be mounted on the substrate 20, and wires between the sensing unit 10 and the components can be formed on the substrate 20.

[0053] Here, the substrate 20 can be a printed circuit board (PCB) or a flexible printed circuit board (FPCB).

[0054] The base component 13 is disposed on the substrate 20, and the terminal component 14 extends from one side of the base 13, for example, from the lower side of the base 13.

[0055] Terminal component 14 passes through an opening formed in substrate 20 and is electrically connected to substrate 20.

[0056] Here, the number of terminal components 14 connected to the substrate 20 is not limited, and for example, four terminal components 14 can be formed, such as... Figure 1B As shown.

[0057] The measuring component 11 is disposed on the base component 13 in a direction opposite to the extending direction of the terminal component 14, for example, in an upward direction from the base component 13.

[0058] The measuring component 11 is in direct contact with the subject's body and measures the subject's body temperature. Here, the measuring component 11 is sufficient to measure the subject's body temperature, and the type of measuring component 11 is not limited.

[0059] The temperature measured by the measuring component 11 is the core body temperature, not the surface temperature of the body. Therefore, the measuring component 11 should be a sensor capable of measuring the core body temperature of the subject.

[0060] Here, as Figure 1A As shown, only the upper surface of the measuring component 11 is exposed, and the other surfaces of the measuring component 11 are covered by the cover component 12.

[0061] The cover component 12 covers the measuring component 11 in the form of a capsule, so that the exposed upper surface of the measuring component 11 is in direct contact only with the subject's body.

[0062] Here, the cover component 12 may include insulating material.

[0063] Therefore, except for the part that comes into contact with the subject's body, the measuring component 11 is completely covered by the cover component 12, which prevents heat from the outside from being transferred to the measuring component 11 and allows for more accurate measurement of the subject's body temperature.

[0064] The cover component 12 includes a measuring sensor (not shown), and the ambient temperature can be obtained through the measuring sensor of the cover component 12. Here, in addition to the core body temperature, the ambient temperature can also be obtained.

[0065] In the present exemplary embodiment, a plurality of slits 21 are formed in a first region A, in which a sensing unit 10 having a base component 13 is installed.

[0066] The slit 21 is an opening formed by passing through the substrate 20. Since the slit 21 is formed by passing through the substrate 20, the sensing unit 10 can be isolated in the substrate 20.

[0067] Here, when the base component 13 has a circular shape, a plurality of slits are formed around the first region A, which has a circular shape, and each slit in the slits is spaced apart from the first region A by a predetermined distance.

[0068] Furthermore, the slits 21 are spaced apart by a predetermined distance. For example, adjacent slits 21 may form a gap 22.

[0069] Therefore, as Figure 1B As shown, when four slits 21 are formed, each slit in slit 21 can be a circumferential slit forming approximately 90°. Furthermore, the slits 21 form circular slits surrounding the first region A, and intervals 22 are formed between adjacent slits. Therefore, intervals 22 are formed at every 90°.

[0070] The sensing unit 10 shall be electrically connected to the elements formed on the substrate 20 to receive power or be controlled by an electrical signal from the substrate 20.

[0071] Therefore, in this exemplary embodiment, the electrical connection for operating the sensing unit 10 is maintained via the interval 22, and all areas surrounding the sensing unit 10 are provided with an opening slit 21 except for the minimum configuration of the electrical connection described above.

[0072] Various components can be mounted on the substrate 20, and the heat generated by the components can be transferred. Therefore, the heat from the substrate 20 can also be transferred to the sensing unit 10. Thus, in addition to the heat from the subject's body, the heat from the substrate 20 will also change the results measured by the sensing unit 10.

[0073] Therefore, the slit 21 formed around the sensing unit 10 can prevent heat from the substrate 20, so the result measured by the sensing unit 10 depends only on the heat from the subject's body, and the measured temperature can be accurate.

[0074] Therefore, the accuracy of the results measured by temperature sensor 1 can be further improved.

[0075] Figure 2A , Figure 2B and Figure 2C It shows that each has Figure 1A Perspective, bottom, and cross-sectional views of a strip-shaped wearable device with a temperature sensor.

[0076] refer to Figure 2A , Figure 2B and Figure 2C In addition to the above references Figure 1A and Figure 1B The temperature sensor 1 explained, the strip-shaped wearable device 30 (hereinafter referred to as the wearable device) according to this exemplary embodiment also includes a housing 35, a strip-shaped component 36, a display component 31, a power supply 32 and a vital signs measurement component 33.

[0077] Temperature sensor 1 and the above reference Figure 1A and Figure 1B The basic principles are the same, and any repeated descriptions will be omitted.

[0078] As shown in the figure, the housing 35 has a front side and a rear side, and the shape of the housing 35 is not limited. The display component 31 is formed on the front side, and the temperature sensor 1, the power supply 32, and the vital signs measuring component 33 are formed on the rear side.

[0079] Here, the rear side, where the temperature sensor 1, power supply 32, and vital signs measuring component 33 are located, is the surface that directly contacts the subject's body (such as the wrist). Therefore, the front side faces outward, and the measurement results of the temperature sensor 1 and vital signs measuring component 33 are displayed by the display component 31 on the front side.

[0080] The strip-shaped component 36 is attached to both sides of the housing 35 and secures the housing 35 to the subject's wrist.

[0081] Therefore, the wearable device 30 is manufactured in a band-like form and is fixed to the subject's wrist.

[0082] Power supply 32 provides power to temperature sensor 1, vital signs measurement component 33 and display component 31.

[0083] Here, as shown in the figure, the temperature sensor 1 is fixed to the housing 35, with the exposed portion of the measuring component 11 facing the lower part of the wearable device 30. Therefore, the body temperature of the subject can be measured through the exposed portion of the measuring component 11.

[0084] In addition to the subject's body temperature measured by temperature sensor 1, vital signs measurement component 33 measures other vital signs information of the subject's body.

[0085] For example, the vital signs measurement component 33 can measure oxygen saturation, pulse, blood pressure and electrocardiogram, and the type or structure of the vital signs measurement component 33 is not limited.

[0086] Therefore, temperature sensor 1 is disposed on the strap-shaped wearable device 30, and the exposed portion of the measuring component 11 of temperature sensor 1 is positioned facing the subject's body. The temperature of the subject's body can then be measured.

[0087] Figure 3A and Figure 3B It shows that each has Figure 1A Perspective and cross-sectional views of a wearable device with a temperature sensor patch.

[0088] refer to Figure 3A and Figure 3B In addition to the above references Figure 1A and Figure 1B The temperature sensor 1 explained, according to the patch-type wearable device 40 (hereinafter referred to as wearable device) of this example embodiment, also includes a vital signs measurement module 41, a communication module 43, a connection component 44, a first electrode 45 and a second electrode 46.

[0089] Here, temperature sensor 1 is basically the same as described above, so any repeated descriptions will be omitted.

[0090] As shown in the figure, the vital signs measurement module 41 can have a flat rectangular block shape, and the vital signs measurement component 42 can be disposed inside the vital signs measurement module 41.

[0091] Here, the vital signs measurement component 42 is the same as the reference above. Figure 2C The vital signs measurement component 33 described is basically the same.

[0092] Furthermore, although not shown in the figure, in addition to the vital signs measurement component 42, other elements capable of measuring other vital signs can be configured in the vital signs measurement module 41, and thus, the other elements and the vital signs measurement component 42 can be formed as a single module.

[0093] The communication module 43 is located on the opposite side of the vital signs measurement module 41, and is separated from the vital signs measurement module 41 by a predetermined distance. Various communication elements can be configured at the communication module 43.

[0094] Therefore, the information obtained by the vital signs measurement module 41 and the temperature sensor 1 can be provided to the outside through the communication module 43.

[0095] The first end of the connecting component 44 is connected to the vital signs measurement module 41, and the second end of the connecting component 44 is connected to the communication module 43. Therefore, the connecting component 44 connects the vital signs measurement module 41 to the communication module 43.

[0096] Here, the temperature sensor 1 is disposed inside the connecting member 44, and the exposed portion of the measuring component 11 of the temperature sensor 1 is fixed to face the lower portion of the connecting member 44.

[0097] Therefore, the measuring component 11 is partially exposed to the outside towards the lower portion of the connecting component 44, and the lower surface of the connecting component 44 is in contact with the subject's body. Thus, the temperature of the subject's body can be measured using the measuring component 11.

[0098] Here, the connecting component 44 has a flexible structure and is easy to bend, so it can be easily positioned at any location on the subject's body with various surface shapes to measure the subject's body temperature.

[0099] Alternatively, the temperature sensor 1 can be located inside the vital signs measurement module 41 and adjacent to the vital signs measurement component 42, rather than inside the connecting component 44. Therefore, when the temperature sensor 1 is located on the connecting component 44, damage to the temperature sensor 1 due to the reconfiguration of the flexible structure of the connecting component 44 can be prevented.

[0100] The first electrode 45 is attached to the lower surface of the vital signs measurement module 41, that is, the surface facing the subject's body. The second electrode 46 is attached to the lower surface of the communication module 43, that is, the surface facing the subject's body.

[0101] The first electrode 45 and the second electrode 46 are electrodes used to measure vital signs, and therefore are directly attached to the subject's body. The electrical signals measured by the first electrode 45 and the second electrode 46 can be provided to the vital sign measurement component 42 of the vital sign measurement module 41.

[0102] Therefore, based on the electrical signals provided by the first electrode 45 and the second electrode 46, the vital signs measurement component 42 can obtain various vital signs of the subject's body.

[0103] Here, the vital signs obtained can be information obtained through electrical signals such as electrocardiogram signals and other signals such as blood oxygen saturation, pulse, and blood pressure.

[0104] Each of the first electrode 45 and the second electrode 46 can be formed as a patch type that is attached to the subject's body; therefore, the wearable device 40 according to this exemplary embodiment is formed as a patch type that is directly attached to the subject's body. Various vital signs, including temperature, can then be obtained.

[0105] Figure 4 It shows the use Figure 1A The flowchart of the core temperature measurement method of the temperature sensor, and Figure 5 It is shown in detail Figure 4 The flowchart of the flowchart.

[0106] refer to Figure 4 and Figure 5 When using the above reference Figure 1A and Figure 1B When the temperature sensor 1 measures the core body temperature of the subject, it acquires the ambient temperature (step S10).

[0107] Here, in addition to the measuring component 11 that measures the subject's body temperature, the temperature sensor 1 may include an additional temperature sensor configured to measure the ambient temperature.

[0108] An additional temperature sensor can be a measuring sensor included in the cover component 12, which can then measure the ambient temperature.

[0109] Alternatively, an additional temperature sensor can be disposed on the substrate 20 of the temperature sensor 1 as an additional sensor. Furthermore, the additional temperature sensor can be disposed as an additional sensor inside the housing 35 of the strip-type wearable device 30, or it can be disposed as an additional sensor inside the vital sign measurement module 41 or the connecting component 44 of the patch-type wearable device 40.

[0110] When acquiring the ambient temperature (step S10), the change in ambient temperature per unit time is measured using an additional temperature sensor (step S11). Then, based on the measurement results of the ambient temperature change, it is determined whether the ambient temperature is in thermal equilibrium (step S12), and then it is determined whether the ambient temperature has been measured.

[0111] Here, an additional control component (not shown) can determine whether the ambient temperature is in thermal equilibrium, and the additional control component can determine thermal equilibrium when the ambient temperature change remains within a predetermined range for a predetermined time.

[0112] Therefore, when the ambient temperature is determined to be in thermal equilibrium (step S12), the ambient temperature T is measured by the additional temperature sensor.A (Step S13).

[0113] Then, the core body temperature is obtained through temperature sensor 1 (step S20).

[0114] Here, temperature sensor 1 uses measuring component 11, which is in contact with the subject's body, to measure the subject's body temperature, and the measured body temperature is considered as core body temperature T. o .

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

[0116] Here, the obtained ambient temperature T is determined. A Does the predetermined condition meet? (Step S31) Based on the ambient temperature range, correct the core body temperature. (Steps S32 and S33)

[0117] For example, when the ambient temperature T A When the first temperature condition is met, which falls within the range of 24°C to 26°C, no correction is made for the core body temperature, and the obtained core body temperature T is recorded. o Core body temperature T (as corrected) c .

[0118] Or, when the ambient temperature T A When the second temperature condition of a temperature below 24°C or above 26°C is met, the core body temperature T is corrected using the following equation (1). o .

[0119] T C =T O +T A ×C W Equation (1)

[0120] Here, T c It is the corrected core body temperature, T o It measures core body temperature, T. A It measures the ambient temperature, and C. w It is the correction factor.

[0121] Correction factor C w These are the predetermined coefficients listed in the supplementary lookup table. For example, correction coefficients can be listed in Table 1.

[0122] Correction factor C w Based on the measured ambient temperature T A The predetermined coefficients, therefore, can be based on the correction coefficient C. w To calculate equation (1), we can then finally obtain the corrected core body temperature T. c (Step S32).

[0123] Therefore, when measuring the temperature of temperature sensor 1, the ambient temperature is obtained first, and then the core body temperature is calibrated. This allows for a more accurate acquisition of the core body temperature.

[0124] [Table 1]

[0125]

[0126]

[0127] According to this embodiment, the measuring component is mounted on the substrate to be operated, but the heat generated by various components may be provided to the measuring component through the substrate, so the measured body temperature of the subject may be inaccurate.

[0128] Therefore, in the present exemplary embodiment, a plurality of slits are formed in the substrate to isolate the first region in which the sensing unit is formed. Thus, heat transfer through the substrate can be minimized, and the measured temperature of the subject's body can be accurate.

[0129] Here, only a portion of the measuring component facing the subject's body is exposed, while the rest of the measuring component is completely covered by a cover, thus ensuring accurate measurement of the subject's body temperature.

[0130] In addition, temperature sensors can be applied to strip-type or patch-type wearable devices. When applied to patch-type wearable devices, the temperature sensor can be mounted on a connecting component with a flexible structure to increase adhesion to the subject's body.

[0131] In addition to body temperature, various vital signs can be obtained in wearable devices, and these vital signs can be obtained using electrodes that come into contact with the subject's body.

[0132] Here, in order to improve the accuracy of core body temperature measurement, ambient temperature is used to correct the core body temperature.
