In addition, in the first prior art, due to the structure of the mat, piezoelectric information about the body parts of the sleeping person (eg, head, calves, etc.) cannot be obtained, and the heat of the heating element can be controlled at different temperatures for each body part. can't In addition, the first prior art does not disclose that each part of the mat generates heat at different temperatures based on the recognition of the sleeper's body part and the body temperature measured from the body part.

In addition, the second prior art (eg, Patent Document 2) discloses a sleep system that repairs, recovers, and regenerates individual cellular tissues, ie, mats, in order to enhance various health-promoting metabolic processes related to sleep. However, this second prior art is not a structure in which at least a portion of the mat can be heated to a different temperature from other portions based on the body part of the sleeping person. In addition, in the second prior art, the heating element corresponding to each body part of the sleeping person cannot be heated to different temperatures due to the structural characteristics of the mat. In addition, the second prior art does not control the temperature of the mat by measuring the body temperature of a body part from the user.

On the other hand, the second user 2320 may take a more comfortable sleep than the first user 2310 and the second user 2330 based on the heat intermediate zone.

According to an embodiment, the processor 126 may heat the temperature of at least one heating element disposed at a position corresponding to each body part among the plurality of heating elements disposed on the mat unit 110 with reference to FIG. 24 . .

For example, the processor 126 may control each temperature controller so that at least one heating element that identifies the weight value for the scalp of the sleeping person ^{is heated to 34.8 o} C, and at least one heating element that identifies the weight value for the chest Each temperature control unit can be controlled so that one heating element ^{heats to 34.5 o C.} And, the processor 126 is the at least one heating element identifying the weight value for the armpit ^{is heated to 36.4 o} C, the at least one heating element identifying the weight value for the arm is heated to 33.5 ^o C, the finger Each temperature control unit corresponding to each heating element may be controlled so that at least one heating element whose weight has been identified for the heating element is ^{heated to 33.2 o C.} In addition, the processor 126 generates at least one heating element that identifies the weight value for the thigh at 33.4 ^o C, and at least one heating element that identifies the weight on the leg heats at 30.1 ^o C, Each temperature control unit corresponding to each heating element may be controlled so that at least one heating element whose weight value is identified ^{for heats up to 29.7 o C.} In addition, the processor 126 may control each temperature control unit corresponding to each heating element so that at least one heating element that identifies the weight value for the toe ^{is heated to 29.1 o C.}

As such, the processor 126 according to an embodiment recognizes the user's body part on the mat unit, and at least one heating element corresponding to the recognized body part heats to a temperature suitable for the recognized body part. The temperature control unit can be controlled.

According to an embodiment, the processor 126 may control a part of the mat unit 110 to a different temperature from that of the other part based on the recognition of the user's body part. In addition, the processor 126 may control a portion of the mat unit 110 to a different temperature from other portions using the user's body temperature (eg, skin temperature or central temperature).

23 and 24 , when a user (eg, a sleeper) sleeps, the temperature corresponding to each body part of the user may be different. Users (eg sleepers) can get optimal sleep in the thermoneutral zone (TNZ) (eg 28-30 ^{oC ).} The processor 126 may control the temperature of a part of the mat unit 110 so that the temperature of each body part becomes a temperature corresponding to each body part in the thermal intermediate zone (or thermal neutral zone) while the user sleeps. have.

For example, the temperature of the scalp in the middle zone is 34.8 ^o C, the temperature of the chest is 34.5 ^o C, the temperature of the armpit is 36.4 ^o C, and the temperature of the arms is 33.5 ^o C. In addition, the temperature of the finger is 33.2 ^o C, the temperature of the thigh is 33.4 ^o C, the temperature of the leg is 30.1 ^o C, the temperature of the foot is 29.7 ^o C, and the temperature of the toe is 29.1 ^o C. The temperature of each body part in the heating intermediate zone may be different depending on the user's environment (eg, whether wearing clothes, whether or not covered with a blanket, ambient temperature, etc.). In addition, the temperature of each body part for each heat intermediate zone according to these various environments is stored in the memory 125 .

25 is an exemplary diagram illustrating a body temperature measuring device having a sensor for measuring a temperature of a body part of a user according to an embodiment of the present invention.

Referring to FIG. 25 , at least one sensor for measuring a temperature of a body part of a user according to an embodiment of the present invention may be included in the patch 2510 . Alternatively, the at least one sensor may be included in the garment 2520 , or may be included in an appropriate location on the earbud 2530 .

According to an embodiment, at least one sensor capable of measuring a temperature may be attached to the patch 2510, and is attached to a part of the body (eg, side, armpit, etc.) to measure the temperature of at least part of the body. can be measured At least one sensor capable of measuring a temperature may be attached to the clothing 2520 and may measure a temperature of at least a part of the body while being worn by the user. In addition, when the earbud 2530 is inserted into the user's ear, the user's skin temperature or central temperature may be acquired through the user's ear.

Such a body temperature measuring device may transmit information about the obtained temperature to the smart mat 100 . In addition, the control device 120 (eg, the processor 126 ) of the smart mat may receive a signal or data including at least one temperature for each body part through the communication unit 123 .

According to one embodiment, the control device 120 (eg, the processor 126) of the smart mat 100 is a user ( For example, temperature information on a body part of a sleeping person) may be received through the communication unit 123 . The control device 120 (eg, the processor 126 ) is configured in at least one (or at least two or more) body parts through at least one of a patch 2510 , a garment 2520 , and an earbud 2530 , respectively. The acquired temperature information may be acquired, and a core temperature and a skin temperature may be identified (or estimated) based on the acquired temperature information.

For example, the processor 126 may be configured to obtain a skin temperature and/or a skin temperature for each body part of the user obtained from at least one sensor included in the patch 2510 , the garment 2520 , and/or the earbud 2530 . Information on the central temperature may be acquired through the communication unit 123 . Although only the patch 2510, the clothing 2520, and the earbuds 2530 are illustrated in FIG. 25, the present invention provides temperature information on body parts through various temperature measuring means capable of measuring the temperature of each body part. can be obtained

26 is an exemplary diagram illustrating temperature sensitivity in each body part in order to estimate the central temperature of the body according to an embodiment of the present invention.

Referring to FIG. 26 , the control device 120 (eg, the processor 126 ) of the smart mat 100 may estimate the central temperature of the user (eg, the sleeping person) based on the temperature sensitivity in each body part. have. In general, the central temperature of the human body can be measured through the heart, esophagus, nasopharynx, rectum, eardrum, bladder, blood, and the like. However, these measurements during sleep can be practically hampered. Accordingly, alternative temperatures measured at body parts of the oral, rectal, axillary, and innet ear can be estimated as the central temperature. According to an embodiment, the control device 120 (eg, the processor 126 ) may estimate the central temperature of the body based on the sensitivity of each body part (eg, torso).

For example, as in the case of FIG. 26(a), when ^{a cold stimulus of 20 °} C is applied to the user's front face, the sensitivity of the face is 7.3, and the sensitivity of the side is 7.1. And, the sensitivity of the center of the body is 7.0, and the sensitivity of the abdomen is 6.9. As such, the parts of the body that are sensitive to cold stimulation are the face, the sides, the middle of the torso, and the abdomen. And, as in the case of FIG. 26 (b), when a 40 ^o C warm stimulus is applied to the user's front view, the sensitivity of the abdomen is 5.5, and the sensitivity of the center of the body is 5.3. And, the sensitivity of the center of the chest is 5.0, and the sensitivity of the left and right sides of the chest is 4.6. As such, the parts of the body that are sensitive to warm stimulation are the abdomen, the middle of the torso, the center of the chest, and the left and right chests in that order.

As shown in FIG. 26 , even if the stimulation of the same temperature is the same, since the degree of stimulation experienced according to body parts is different, the control device 120 (eg, the processor 126 ) may include at least one body temperature measuring device 2510 , 2520 . , 2530), it is possible to estimate the central temperature of the body through the measured temperature and sensitivity. For example, since the sensitivity of the torso part of each body is higher than that of other body parts, the control device 120 (eg, the processor 126 ) performs the control on the body part (eg, the torso) having such high sensitivity. Through the measured temperature, it can be estimated as the central temperature of the user (eg, a sleeping person).

27 is an exemplary diagram illustrating an actual central temperature and a temperature of a body part having a temperature similar to the actual central temperature by age group according to an embodiment of the present invention.

Referring to FIG. 27 , the actual core temperature and the temperature of a body part having a temperature similar to the actual core temperature according to an embodiment of the present invention have a slight difference depending on age groups (eg, infants, children, adults, or the elderly). there may be

For example, the core temperature for infants and children ranges from 36.4 ^o C to 37.8 ^o C, and for adults ranges from 36.8 ^o C to 37.9 ^o C. And, the central temperature of the elderly ranges from 35.9 ^o C to 37.1 ^o C. During sleep, the core temperature is not fixed and can change continuously. For example, the core temperature continuously decreases as sleep begins, and may gradually rise from 1 to 3 hours before waking up. Due to this change in the central temperature, the temperature in each body part may also change. In addition, the central temperature of each age group is not fixed and may exist within a certain range. In addition, body parts having a temperature similar to the central temperature (ie, an alternative temperature) may be different for each age group.

For example, the central temperature of infants and children is similar to the temperature measured in the ear, while the central temperature of adults is similar to the temperature measured in the armpit. In addition, the central temperature of the elderly is similar to the temperature measured in the oral cavity. As such, the core temperature may be different for each age group, and body parts for obtaining an alternative temperature that can replace the central temperature of each age group may also be different. Since measuring the central temperature of the body may be difficult in reality, an embodiment of the present invention provides a temperature in a body part that can replace the central temperature according to each age group (eg, in the ear, armpit, or oral cavity) can be replaced by the central temperature.

According to an embodiment, the control device 120 (eg, the processor 126 ) uses at least one body temperature measuring device 2510 , 2520 , and 2530 based on the temperature obtained from the body part, the mat unit 110 . It is possible to identify the user's age group and the central temperature corresponding to each age group.

According to an embodiment, the central temperature may start to decrease as the sleep time is near and may be the lowest in a period in which a deep sleep is taken. And, the closer the wake-up time, the closer the core temperature starts to rise.

28 is an exemplary view illustrating changes in central temperature, plasma cortisol, and plasma melatonin during sleep according to an embodiment of the present invention.

Referring to FIG. 28 , the central temperature, plasma cortisol, and plasma melatonin according to an embodiment of the present invention may change during sleep ( 2840 ). The central temperature 2810 is a temperature measured through the heart, esophagus, nasopharynx, rectum, eardrum, bladder, blood, and the like. The central temperature 2810 is a substance secreted in response to acute stress, and the plasma cortisol 2820 serves to supply energy necessary for the body to counteract the stress. In addition, plasma melatonin 2830 is a biological hormone secreted from the brain, and acts to induce natural sleep.

As shown in FIG. 28 , the central temperature 2810 is about 37.5 ^o C before sleep (before about 24 hours), but may gradually lower to about 36.2 ^{o C as sleep begins.} In addition, the central temperature gradually increases from a predetermined time (eg, about 1 to 3 hours before) from the time of waking up (eg, about 06:00). In addition, the temperature of the proximal skin close to the central temperature during sleep is lowered like the central temperature, and the temperature of the distal skin may be increased to effectively dissipate heat.

In addition, plasma cortisol (2820) is gradually lowered to about 3 ug/dl before sleep (before about 24 hours), but begins to gradually increase as sleep begins, and continues to about 28 ug/dl 1 hour after waking up increases to In addition, plasma melatonin 2830 is secreted at about 4 pmol/L before sleep (before about 24 hours), and when sleep begins, the secretion starts to increase. In addition, the plasma melatonin 2830 secretion increases up to 76 pmol/L during deep sleep (about 03 o'clock), and thereafter, the secretion amount gradually decreases.

As such, core temperature 2810 , plasma cortisol 2820 , and plasma melatonin 2830 change during sleep. In this way, the control device 120 (eg, the processor 126) may identify the central temperature based on the temperature obtained from the body part using at least one body temperature measuring device 2510, 2520, 2530, Whether the user is currently sleeping or not sleeping may be identified based on the identified change in the central temperature.

29 is an exemplary view showing the central temperature and the skin temperature according to the ambient temperature according to an embodiment of the present invention.

Referring to FIG. 29 , the body temperature may be affected by the ambient temperature. The body's core temperature tries to keep the temperature constant regardless of the outside temperature (eg outside air temperature), whereas the skin temperature can easily change with changes in the outside temperature (eg outside air temperature). And, the central temperature ^{may be in the range of about 36.5 o} C to 37.2 ^o C (± 0.2).

For example, the central temperature 2910 ^{may be maintained within a uniform temperature range (about 36.5 °} C to 37.2 ^° C (± 0.2)) regardless of changes in ambient temperature. In addition, the replacement temperature 2920 that can replace the center temperature may be slightly affected by changes in ambient temperature, and may be lower than the center temperature.

For example, if the ambient temperature is 35 ^° C and 23 ^° C, the central temperature 2010 may be equal to ^{37 °C.} However, when the ambient temperature is 35 ^° C, the region within the body where the central temperature is 37 ^° C may be greater than when the ambient temperature is 35 ^°C. And, when the ambient temperature is 35 ^o C and 23 ^o C, an alternative temperature that can replace the central temperature in the body is 37 ^o C, and it can be measured in a part of the body (eg, armpit, flank, etc.). And, when the ambient temperature is 23 ^o C, the skin temperature 2930 may decrease further toward the end of the body (eg, arms, legs, etc.).

According to an embodiment, the control device 120 (eg, the processor 126 ) determines the current ambient temperature based on the temperature obtained from the body part using at least one body temperature measuring device 2510 , 2520 , and 2530 . can be estimated Alternatively, the control device 120 (eg, the processor 126 ) may identify the measured location of the skin based on the current ambient temperature and the skin temperature.

30A is an exemplary view illustrating a change in external temperature according to an embodiment of the present invention. 30B is a diagram illustrating a change in the central temperature at work according to a change in the external temperature according to an embodiment of the present invention. 30C is a diagram illustrating a change in a central temperature in a skin temperature according to a change in an external temperature according to an embodiment of the present invention.

Referring to (a) of FIG. 30 , the first condition 3010 is that the ambient temperature is lowered over time, and the second condition 3020 is that the ambient temperature is maintained at a constant temperature (eg, 28oC). . And, the third condition 3030 is a condition in which the ambient temperature is lowered over time. For example, the first condition 3010 is that the ambient temperature is ^{decreased by 0.5 o C from 30 o} C in 1 hour increments for 9 hours, and the second condition 3020 is that the ambient temperature is maintained at 28 o C for 9 hours. will be. And, the third condition 3030 is that the ambient temperature is increased by ^{0.5 o C from 26 o} C in units of 1 hour for 9 hours.

Referring to (b) of FIG. 30 , the rectal temperature in the first condition 3010 decreases for about 2 hours after measurement, and then gradually increases as time passes. And, the rectal temperature in the third condition 3030 gradually rises for about 5 hours after the measurement, and then gradually decreases over time. In contrast, the rectal temperature in the second condition 3020 is relatively uniform compared to the first condition 3010 and the second condition 3030 .

Referring to (c) of FIG. 30 , the skin temperature in the first condition 3010 decreases slightly for about 3 hours after measurement, and the skin temperature gradually rises after about 3 hours. And, the skin temperature in the third condition 3030 continuously decreases over time. In contrast, the skin temperature under the second condition 3020 is relatively uniform compared to the first condition 3010 and the second condition 3030 .

According to an embodiment, when the external temperature changes, the control device 120 (eg, the processor 126 ) is less sensitive to the central temperature (eg, the temperature measured at work) than the skin temperature, and the skin temperature is the central temperature. It can be identified that it is more sensitive than temperature.

31 is an exemplary view showing a change in the central temperature during sleep according to an embodiment of the present invention.

Referring to FIG. 31 , the central temperature during sleep according to an embodiment of the present invention may be changed during sleep. For example, as the sleep time is closer, the core temperature may decrease, and the decrease in the core temperature (eg, a decrease from about 36.9 ^o C to about 36.5 ^o C) in the first sleep period may be accelerated. Thereafter, the central temperature in the second sleep section, which is the deep sleep section, has a range of about 36.2 ^o C to 36.5 ^o C, and the central temperature in the third sleep section, which is the awakening section, gradually increases from ^{36.3 o C.} As described above, after the central temperature gradually decreases while entering the water surface, the central temperature in the deep sleep section may be lower than the central temperature in other sections. And, the central temperature gradually rises in the awakening section (eg, 1 to 3 hours before waking up).

According to an embodiment, the first sleep period is an initial sleep period, and the control device 120 (eg, the processor 126 ) initiates sleep using at least one thermometer 2510 , 2520 , and 2530 . can detect The control device 120 (eg, the processor 126 ) may control the temperature of the mat unit 110 according to the ambient temperature so that sleep is good in the initial sleep period.

According to an embodiment, the second sleep period is a mid-sleep period, and the control device 120 (eg, the processor 126) is configured to effectively dissipate heat from the extremities (eg, hands and feet) of the body, The temperature of the at least one heating element 111 of the mat unit 110 may be controlled so that the temperature of the proximal portion close to the center temperature corresponds to the heating intermediate zone. The control device 120 (eg, the processor 126 ) may lower the temperature of the at least one heating element 111 of the mat unit 110 in order to lower the temperature of the end portion of the body.

According to an embodiment, the third sleep section is a late sleep section, and the control device 120 (eg, the processor 126 ) uses at least one body temperature measuring device 2510 , 2520 , and 2530 to determine the central temperature. It can be seen that it is rising. In addition, the control device 120 (eg, the processor 126 ) controls the at least one heating element so that the temperature of the at least one heating element 111 of the mat unit 110 is similar to the elevation induction period in the sleep end section. The temperature of (111) can be controlled.

According to an embodiment, the control device 120 (eg, the processor 126 ) uses the at least one body temperature measuring device 2510 , 2520 , and 2530 , and based on the temperature obtained from the body part, the user (eg, sleep I) can identify sleep patterns. For example, the control device 120 (eg, the processor 126) determines whether the user is currently in deep sleep (NREM) based on the temperature obtained using the at least one body temperature measuring device 2510, 2520, 2530; It can identify whether you are in light sleep (REM) or awake.

As described above, during sleep, since the central temperature is not fixed and continuously changes, the control device 120 (eg, the processor 126 ) during sleep may control at least one of the mat unit 110 based on the change in the central temperature. It is possible to control the temperature of the heating element 111 of the.

32 is an exemplary diagram illustrating a sleep pattern of a sleeper according to an embodiment of the present invention.

Referring to FIG. 32 , the sleeper according to an embodiment of the present invention has deep sleep (NREM) 331, 332, 333, 334, 335 and light sleep (REM) 321, 322, 323, 324, 325) can alternately sleep. The sleeper takes deep sleep (NREM) as he enters the fourth stage of sleep from the awakening stage, and takes shallow sleep (REM) as he enters the awakening stage from the fourth stage of sleep again. During these sleep periods, the sleeper can alternate between deep sleep (NREM) and light sleep (REM) sleep. REM sleep occurs periodically over time, and the duration of REM sleep also increases. And, as time goes by, the time of deep sleep (eg, stage 4 sleep) gradually decreases, and the time of REM sleep gradually increases.

33 is an exemplary view showing a heating intermediate zone according to an embodiment of the present invention.

Referring to FIG. 33 , the thermal intermediate zone according to an embodiment of the present invention may mean a temperature region having the lowest basal metabolic rate (BMR). The thermal intermediate zone 3320 is a temperature region in which the basal metabolic rate required for physiological temperature regulation of the sleeping user's body is low (or the region near the lowest point), and the temperature at which the amount of oxygen consumed during sleep is minimized. is the area

For example, the basal metabolic rate of the sleeping user decreases 3310 in inverse proportion to the increase in ambient temperature, and when the ambient temperature falls within a certain range (eg, about 27 ^o C ~ 33 ^o C), the basal metabolic rate is further is not reduced any more. As such, the temperature range in which the basal metabolic rate is no longer reduced may be referred to as the thermal intermediate zone. In addition, when the ambient temperature exceeds a certain range (eg, about 27 ^o C ~ 33 ^o C) corresponding to the thermal intermediate zone, the basal metabolic rate may be increased ( 3330 ). In this way, the temperature section 3320 in which the oxygen consumption during sleep is minimized may be estimated as the thermal intermediate zone. For example, in the case of an undressed adult male, the mid-heat zone is about 27 ^o C to 33 ^o C, and for an adult female, the range of the mid-heat zone may be slightly wider than that of an adult male. This middle zone of heat may vary according to various circumstances, such as age, gender, and whether or not to wear clothes. The temperature for the thermal intermediate zone according to these various environments may be stored in the memory 125 .

And, when the ambient temperature is lower than the minimum temperature of the thermal intermediate zone (eg, about 27 ^o C), the body's core temperature is about 36 ^o C ~ 38 ^o C, which is not significantly affected by the change in the ambient temperature. However, the skin temperature of the body in the thermal intermediate zone (eg about 27 ^o C to 33 ^o C) may increase proportionally to the increase in ambient temperature. And, when the ambient temperature is greater than the maximum temperature of the middle zone (eg, about 33 ^o C), the sleeper sweats during sleep.

According to an embodiment, the processor 126 obtains body temperature for each body part of the user (eg, a sleeping person), and the obtained body temperature for each body part is body temperature for each body part corresponding to the thermal intermediate zone. It is possible to control the temperature of at least one heating element of the mat unit 110 to match or similar to.

34 is an exemplary diagram illustrating a relationship between a central temperature and a thermal intermediate zone according to an embodiment of the present invention.

In general, it may be inconvenient for a user to sleep while wearing a breathing gas analyzer. Therefore, after wearing the analyzer, measuring oxygen consumption during sleep can be practically difficult. For this reason, the control device 120 (eg, the processor 126 ) of the smart mat 100 according to an embodiment of the present invention uses oxygen consumption by using the change in the central temperature as the sleep time increases during sleep. This small section can be identified, and the heat intermediate zone can be identified through the section with a low oxygen consumption.

Referring to FIG. 34 , the central temperature according to an embodiment of the present invention is gradually lowered as sleep begins. And, as the awakening time (eg, wake-up time) approaches, the core temperature rises again. For example, if the sleeping person wears clothes, the optimal temperature for sleeping is about 17 ^o C ~ 20 ^o C due to the thermal effect of the clothes, and when the sleeper wears clothes, the optimal temperature for sleeping is about 28 ^o C to 30 ^o C.

For example, the central temperature when the sleeper begins to sleep based on the optimal temperature for sleep is about 36.8 ^° C. And, as the sleep time increases, the core temperature gradually decreases, and when about 3 hours of sleep time elapses, the core temperature is lowered to ^{about 36.3 o C.} Thereafter, the core temperature gradually increases as the awakening time (eg, wake-up time) approaches. As such, the central temperature has a pattern of gradually lowering over the sleeping time and then rising again. In addition, the thermal intermediate zone is a temperature zone in which oxygen consumption is minimized during sleep. The pattern of oxygen consumption during sleep may be similar to the pattern of core temperature during sleep.

According to an embodiment, the control device 120 (eg, the processor 126) obtains an alternative temperature (eg, armpit, in the ear, in the oral cavity, etc.) that can replace the central temperature from the sleeping user, Based on the obtained replacement temperature, it is possible to identify (or estimate) the central temperature of the sleeping user. The control device 120 (eg, the processor 126 ) may identify (or estimate) a thermal intermediate zone having a pattern similar to the pattern of the central temperature based on the estimated central temperature. In addition, the control device 120 (eg, the processor 126 ) determines the temperature at which at least one heating element 111 of the mat unit 110 located in each body part of the sleeping person corresponds to each body part in the heating intermediate zone. It is possible to control the temperature of at least one heating element of the mat unit 110 so as to generate heat.

According to one embodiment, the control device 120 (eg, the processor 126) through the image acquired from the camera 1110 (eg, a vision camera, an infrared camera, a thermal imaging camera, etc.) the sleeper's current clothes It can be identified whether it is worn or covered with a duvet. For example, when the control device 120 (eg, the processor 126 ) is wearing clothes or is covered with a blanket, the temperature increase by the clothes and the blanket can be applied to the temperature measured at the body part. have. In addition, the control device 120 (eg, the processor 126 ) determines the temperature at which at least one heating element 111 of the mat unit 110 located in each body part of the sleeping person corresponds to each body part in the heating intermediate zone. It is possible to control the temperature of the at least one heating element of the mat unit 110 so as to generate heat.

For example, when the central temperature of the sleeping user is about 36.3 ^o C to 36.7 ^o C, the control device 120 (eg, the processor 126 ) identifies that the thermal intermediate zone is 28 ^o C to 30 ^{o C} can do. And, as shown in FIG. 24 , the control device 120 (eg, the processor 126 ) controls the mat unit 111 corresponding to each body part based on the temperature of each body part corresponding to the identified thermal intermediate zone. ), it is possible to control the temperature of the at least one heating element 111 in the mat portion 111 so that a portion of the heat.

35 is a flowchart illustrating a process of controlling the operation of the smart mat according to an embodiment of the present invention.

Hereinafter, a process for controlling the operation of the smart mat according to an embodiment of the present invention will be described in detail with reference to FIG. 35 .

According to an embodiment, the processor 126 of the smart mat 100 may acquire piezoelectric information by the user on the smart mat at each position of at least one piezoelectric sensor provided in the smart mat (S3510). According to an embodiment, when the user is lying on the mat unit 110 , the processor 126 may receive a signal for detecting the weight of the user from at least one piezoelectric sensor. The processor 126 of the user obtained by at least one piezoelectric sensor disposed at a distance (eg, 1 cm, 5 cm, or 10 cm, etc.) (or variable intervals) spaced apart from the mat unit 110 Piezoelectric information on the body part may be obtained from at least one piezoelectric sensor through wireless communication or wired communication.

According to an embodiment, when a user (eg, a sleeping person) covers the blanket on the mat unit 110 , each of the at least one piezoelectric sensor 112 is located at the user's position on the mat unit 110 (eg, : It is possible to obtain piezoelectric information (eg, the weight value of the user's body part and the weight of the blanket covering the body part) by the sleeping person covering the quilt. For example, if the user wants to obtain a weight value of only a part of the user's body in a state in which the user is covering the blanket, the processor 126 covers the body part from the weight value of the body part covering the blanket. By subtracting the weight value of the blanket, it is possible to obtain a weight value of only a part of the user's body.

According to an embodiment, the process ( S3510 ) may include at least one function or process described in FIGS. 3 , 15 , and 21 . In addition, the description of the process ( S3510 ) may apply at least one function or process described in FIGS. 3 , 15 , and 21 .

According to an embodiment, the processor 126 may acquire information on at least one temperature identified from the user's body (S3512).

36 is a flowchart illustrating a process of controlling the operation of the smart mat according to another embodiment of the present invention.

Hereinafter, a process for controlling the operation of the smart mat according to another embodiment of the present invention will be described in detail with reference to FIG. 36 .

According to an embodiment, the processor 126 may acquire piezoelectric information by a user on the smart mat at each location of at least one piezoelectric sensor provided in the smart mat (S3610). According to an embodiment, the processor 126 may obtain information on at least one temperature identified from the user's body (S3612). Each of the processes S3610 and S3612 may include at least one function or process described in FIGS. 3, 15, 21, and 35 . In addition, for the description of the processes S3610 and S3612, at least one function or process described in FIGS. 3, 15, 21, and 35 may be applied.

According to an embodiment, the processor 126 may identify the user's central temperature based on the at least one acquired temperature (S3614). The processor 126 obtains temperature information measured in at least one body part through at least one of the patch 2510 , the clothing 2520 , and the earbud 2530 , and based on the obtained temperature information, a central temperature can be identified (or estimated). The obtained temperature information is a replacement temperature capable of replacing the central temperature. The processor 126 may receive information on at least one temperature measured in each body part, and apply a temperature included in the received information as an alternative temperature to replace the central temperature. The replacement temperature is a temperature similar to the core temperature, and is a temperature measured in a body part (eg, in the ear, armpit, oral cavity, etc.).

Body parts having a temperature similar to the central temperature of the human body may be different for each age group. For example, the central temperature of infants and children is similar to the temperature measured in the ear, while the central temperature of adults is similar to the temperature measured in the armpit. In addition, the central temperature of the elderly is similar to the temperature measured in the oral cavity. As described above, since it may be difficult to actually measure the core temperature, a temperature (eg, replacement temperature) measured at a body part that generates heat at a temperature similar to the core temperature may be replaced with the core temperature.

According to an embodiment, the processor 126 may identify (or estimate) a central temperature based on a temperature measured in a part of the user's body, based on FIG. 27 .

According to an embodiment, the processor 126 may identify a heating intermediate zone based on the identified central temperature (S3616). The thermal intermediate zone may refer to a temperature range in which the basal metabolic rate (BMR) is no longer reduced. The thermal intermediate zone is a temperature range in which the basal metabolic rate required for physiological temperature regulation of the sleeping user's body is no longer reduced, and may include a temperature region in which the amount of oxygen consumed during sleep is minimized. As such, the temperature range in which the basal metabolic rate is no longer reduced may be referred to as the thermal intermediate zone. This middle zone of heat may vary according to various circumstances, such as age, gender, and whether or not to wear clothes. The memory 125 may store temperature information about the thermal intermediate zone according to these various environments. The memory 125 stores information on the temperature of each body part for providing optimal sleep for each heat intermediate zone according to the various environments.

According to an embodiment, the processor 126 controls the temperature of at least one heating element provided in the smart mat to be heated to different temperatures at a location corresponding to a part of the user's body based on the identified heating intermediate zone. It can be (S3618). According to an embodiment, the processor 126 may control the temperature of at least one heating element provided in the smart mat based on the piezoelectric information and the temperature of each body part corresponding to the identified thermal intermediate zone. .

According to an embodiment, the processor 126 may control the temperature of at least one heating element corresponding to each body part based on the piezoelectric information and the temperature corresponding to each body part corresponding to the identified thermal intermediate zone. can For example, if the temperature of the scalp in the middle zone providing an optimal sleeping environment is 34.8 ^o C, the processor 126 may set at least corresponding to the user's head so that the temperature of the current user's scalp becomes 34.8 ^{o C.} The temperature of one first heating element (eg, at least one heating element corresponding to at least one piezoelectric sensor sensing the weight of the head) may be controlled. In addition, when the temperature of the thigh in the warm middle zone that provides the optimal sleeping environment is 33.4 ^o C, the processor 126 may select at least one corresponding to the user's thigh so that the current temperature of the user's thigh becomes 33.4 ^{o C.} The temperature of the second heating element (eg, at least one heating element corresponding to at least one piezoelectric sensor sensing the weight of the thigh) may be controlled.

As such, the processor 126 is configured to at least correspond to the position of the user's first body part (eg, the scalp) based on the piezoelectric information, at least one temperature (alternative temperature) obtained from the body part, and the thermal intermediate zone. At least one second heating element corresponding to a temperature of one first heating element (eg, at least one heating element corresponding to at least one piezoelectric sensor sensing the weight of the head), and a position of a second body part (eg, thigh) The temperature of (eg, at least one heating element corresponding to at least one piezoelectric sensor sensing the weight of the thigh) may be controlled. The processor 126 may control the temperature of the first heating element or the second heating element so that the temperature of the at least one first heating element is different from the temperature of the at least one second heating element. The processor 126 may control the temperature of the at least one first heating element or the at least one second heating element by controlling at least one of each temperature controller and a temperature control sensor.

Each step in each of the above-described flowcharts may be operated regardless of the illustrated order, or may be performed simultaneously. In addition, at least one component of the present invention and at least one operation performed by the at least one component may be implemented in hardware and/or software.
