However, such a conventional bar magnifying glass thermometer is inconvenient to be put on the side of a subject for measurement for a long time due to the glass rod shape, When the thermometer is released, it becomes impossible to measure the temperature or falls on the floor, causing various problems such as leakage of mercury due to breakage.

Because of the inconvenience of such measurement, it was not possible to measure the changing body temperature from time to time. Therefore, the health condition of the infant became worse due to lack of emergency treatment for the infant who missed the treatment period or fever.

In order to solve such a problem, a method of continuously measuring the temperature by attaching a patch having a temperature sensor to the body has been developed. However, since such a patch has to be provided with a power source for operating the temperature sensor, there is a problem that it is not comfortable to wear due to its heavy weight, and the battery is made of mercury or nickel, which may adversely affect the body when worn for a long time , Ventilation and sweat discharge during the long-time attachment is not smooth, so it is often the case that the infant or sensitive person uses the skin when it is used.

1 to 7 are views for explaining an electroless body temperature sensing apparatus.

A body temperature sensing apparatus (100, 200) according to an embodiment of the present invention includes a substrate (110, 210), a temperature sensor chip (10) mounted on a substrate, And a second electrode 130 and 240 electrically connected to terminals of the temperature sensor chip 120. The substrates 110 and 210 may include a plurality of perforated holes 111, And at least one end of the first electrodes 120 and 220 and the second electrodes 130 and 240 may be electrically connected to each other.

Here, the non-powered body temperature sensing device may be divided into a double-sided structure or a sectional structure depending on the positions of the first electrodes 120 and 220 and the second electrodes 130 and 240 on the substrate. Therefore, the following non-powered body temperature sensing apparatus will be described by dividing the non-powered body temperature sensing apparatus 100 having a double-sided structure and the non-powered body temperature sensing apparatus 200 having a sectional structure.

1 to 4 are views for explaining an electroless body temperature sensing apparatus 100 having a double-sided structure. Here, the double-sided structure means a structure in which different electrodes are formed on both sides of a substrate.

FIG. 1 shows a configuration of an electroless body temperature sensing apparatus 100 having a double-sided structure according to an embodiment of the present invention, and FIG. 2 illustrates an electroluminescence body temperature sensing apparatus 100 having a double-sided structure according to an embodiment of the present invention. FIG. 3 is a side view of the non-powered body temperature sensing apparatus 100 having a double-sided structure according to an embodiment of the present invention, and FIG. 4 is a side view of the non-powered body temperature sensing apparatus 100 according to an embodiment of the present invention. (Portion A-A 'in Fig. 2) of the first embodiment.

Referring to FIGS. 1 to 4, a non-powered body temperature sensing apparatus 100 having a double-sided structure according to an embodiment of the present invention includes a substrate 110, a temperature sensor And a second electrode (130) electrically connected to a terminal of the temperature sensor chip, wherein the substrate (110) has a plurality of perforated holes And at least one end of the first electrode 120 and the second electrode 130 may be electrically connected to each other. Particularly, the first electrode 120 may be formed on the first surface of the substrate 110, and the second electrode 130 may be formed on the second surface of the substrate 110. Here, if the first side refers to either side of the substrate 110, the second side refers to the opposite side.

The substrate 110 may be rigid or flexible. For example, the substrate 110 may comprise glass or plastic. In detail, the substrate 110 may include a chemically reinforced / semi-tempered glass such as soda lime glass or aluminosilicate glass, a polyimide (PI), a polyethylene terephthalate (PET) , Propylene glycol (PPG) polycarbonate (PC), or the like, or may include sapphire.

In addition, the substrate 110 may include an optically isotropic film. For example, the substrate 110 may include a cyclic olefin copolymer (COC), a cyclic olefin polymer (COP), a polycarbonate (PC), a light polymethyl methacrylate (PMMA), or the like.

Sapphire has excellent electrical properties such as dielectric constant, which not only greatly improves the speed of touch reaction but also can easily realize space touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

In addition, the substrate 110 may be curved with a partially curved surface. That is, the substrate 110 may be partially flat and partially curved with a curved surface. In detail, the end of the substrate 110 may have a curved surface, or may have a surface including a random curvature, and may be bent or bent.

In addition, the substrate 110 may be a flexible substrate having a flexible characteristic, or may be a curved or bended substrate. That is, the touch window including the substrate 110 may be formed to have a flexible, curved, or bent characteristic. Accordingly, the non-powered body temperature sensing apparatus 100 according to the embodiment is easy to carry, can be changed into various designs, and the shape of the body can be changed according to the movement of the body, so that the body temperature can be continuously sensed.

The substrate 110 may include a plurality of perforated holes 111 sized to allow ventilation and sweat discharge, wherein the ventilation holes 111 are formed in the upper surface of the substrate 110, The first electrode 120 and the second electrode 130 may be formed in a region other than the region where the first electrode 120 and the second electrode 130 are formed. When the vent hole 111 is pierced in addition to the portion where the first electrode 120 and the second electrode 130 are formed, foreign matter may penetrate from the outside, thereby preventing a malfunction that changes the mechanical and electrical functions of the non-powered body temperature sensing apparatus.

Meanwhile, in order to measure an appropriate size of the ventilation hole 111, experiments were conducted by fabricating the ventilation holes 111 in various sizes. When the diameter of the ventilation hole 111 was 1.0 mm or more, the durability of the substrate was weakened, The substrate may be damaged. In addition, when the diameter is 0.3 mm or less, evaporating water is formed in the vent hole 111, and the vent hole 111 is clogged, so that ventilation is not smooth. Therefore, it was found that the diameter of 0.3mm ~ 1.0mm is suitable for durability of the substrate and smooth ventilation. However, when the diameter is 1.0 mm, the substrate is damaged due to the movement of the body after about 24 hours after wearing the patch on the body.

Thus, when the diameter was made 0.7 mm, even if used for 24 hours or more, there was almost no damage to the substrate. However, when used for more than 7 days, fine dust or the like in the air easily permeated and the vent hole 111 was clogged.

When the diameter was 0.5 mm, it was confirmed that the durability was maintained and the penetration of foreign matter was small and the discharge of sweat was smooth. Therefore, it has been confirmed that the ventilation hole 111 of the present invention is most suitable for durability and smooth skin breathing with a diameter of 0.3 mm to 0.5 mm.

A patch having a conventional temperature sensor is not smoothly ventilated and sweated when it is attached for a long period of time, so that a baby or a person sensitive to skin may suffer skin trouble when used. Therefore, according to the present invention, ventilation holes (111) are drilled in the substrate (110) to smooth ventilation and sweat discharge at the patch attachment sites, thereby reducing the possibility of infants or sensitive skin .

On the other hand, electrodes may be formed on both sides of the substrate 110 due to the characteristics of the present invention having a double-sided structure. The substrate 110 may include a first electrode 120 formed on a first surface and a second electrode 130 formed on a second surface of the substrate 110.

At this time, at least one of the first electrode 120 and the second electrode 130 may include a transparent conductive material so that electricity can flow without disturbing the transmission of light. For example, the electrode may include indium tin oxide and may include metal oxides such as indium tin oxide, indium zinc oxide, copper oxide, tin oxide, zinc oxide, titanium oxide, and the like. have.

Or at least one of the first electrode 120 and the second electrode 130 may include a nanowire, a photosensitive nanowire film, a carbon nanotube (CNT), a graphene, or a conductive polymer.

Meanwhile, the first electrode 120 may be formed on the first surface of the substrate 110 and may be wound in a coil shape to generate an induced electromotive force. The relative motion of the magnet and the coil induces a current in the coil, which is called the induced electromotive force. When a magnetic external device approaches the first electrode, a magnetic field is changed at the center of the first electrode wound around the first electrode, so that an induced electromotive force is generated and an induced current flows through the first electrode. The temperature sensor chip 10 can be operated by the induced current generated at this time. Therefore, the present invention can operate without a battery, so that it is thin and light compared with a conventional patch for detection, so that the wearer can keep the attachment state even when attached to the body, and there is no need to worry about mercury discharge of the battery, There are advantages.

The second electrode 130 is formed on the second surface of the substrate 110, and various chips for sensing a biological signal can be mounted. At this time, the first electrode 120 and the second electrode 130 are formed on the first and second surfaces of the substrate 110 to prevent the first electrode 120 and the second electrodes 130 from being short-circuited can do. Also, since the second electrode 130 must be supplied with the induced electromotive force from the first electrode 120, one end of the first electrode 120 may be connected to one end of the second electrode 130.

In addition, according to another embodiment of the present invention, the NFC coil may further include a communication unit for transmitting and receiving information to / from an external device. The NFC coil may transmit and / or receive a signal generated by an NFC coil, And generates a signal for transmitting and receiving temperature information sensed by the temperature sensor chip 10 to and from the external device while generating the induced electromotive force and operating the temperature sensor chip 10. At this time, May be connected to the terminals of the mounted temperature sensor chip 10.

Near field communication (NFC) is a non-contact communication technology that uses the frequency band of 13.56 MHz as one of the RFID technologies. It is a next-generation LAN technology that is attracting attention due to its relatively low security and relatively low price because of its short communication distance. Because NFC can use both data reading and writing functions, there is no need for a reader that was previously required for the use of radio frequency identification (RFID). It is similar to existing short distance communication technology such as Bluetooth but it does not need to set up connection between devices like Bluetooth. Therefore, if an external device having an NFC function is contacted with the present invention, the temperature can be measured automatically and quickly.

If a magnetic field change occurs in the NFC coil by an external device, an induced current is generated in the NFC coil to operate the temperature sensor chip 10 connected to the second electrode 130, and the information sensed by the temperature sensor chip 10 And is transmitted to the NFC coil to generate a signal for transmitting / receiving information to / from an external device. Therefore, the present invention is advantageous in that the temperature can be easily measured through an external device at any time as long as it is attached to the body.

3, another embodiment of the present invention further includes a via hole 140 passing through the substrate 110. The first electrode 120 is electrically connected to the second electrode 130 via the via hole 140, Lt; / RTI > At this time, an induced current or a received signal formed in the first electrode 120 can reach the temperature sensor chip 10 through the second electrode 130 connected to the first electrode 120 through the via hole 140. A transmission signal generated in the temperature sensor chip 10 can be transmitted to the first electrode 120 connected to the second electrode 130 through the via hole 140.

In another embodiment of the present invention, a first cover layer 150 surrounding the first electrode 120 and a second cover layer 160 surrounding the second electrode 130 may be further included. The first cover layer 150 keeps mechanical and electrical functions while blocking the first electrode 120 from the outside, and protects the characteristic of the first electrode 120 from being changed by protecting it from penetration of foreign matter. The second cover layer 160 also protects the second electrode 130 from the outside while maintaining the mechanical and electrical functions and protects the second electrode 130 from being changed by protecting the second electrode 130 from penetration of foreign matter. More specifically, the second cover layer 160 may surround the second electrode 130 including the temperature sensor chip 10. The second cover layer 160 may surround the second electrode 130 except for a portion where the temperature sensor chip 10 is mounted. The temperature sensor chip 10 can be replaced when the second cover layer 160 surrounds the second electrode 130 except for the portion where the temperature sensor chip 10 is mounted.

Especially at this time

The first electrode 220 and the second electrode 240 may be formed on one surface of the substrate 210 and may further include an insulating layer 230 formed between the first electrode 220 and the second electrode 240 have.

Also, the substrate 210 may be curved with a partially curved surface. That is, the substrate 210 may be partially flat and partially curved with a curved surface. In detail, the end of the substrate 210 may have a curved surface or a curved surface with a random curvature, and may be curved or bent.

In addition, the substrate 210 may be a flexible substrate having a flexible characteristic, or may be a curved or bended substrate. That is, the touch window including the substrate 210 may be formed to have a flexible, curved, or bent characteristic. Accordingly, the non-powered body temperature sensing apparatus 200 according to the embodiment is easy to carry and can be changed into various designs, and the shape of the body can be changed according to the movement of the body, so that the body temperature can be continuously sensed.

More specifically, the ventilation hole 211 may be formed in an area other than the area where the first electrode 220 and the second electrode 240 are formed, for normal operation of the non-powered body temperature sensing apparatus. When the vent hole 211 is punched in a portion where the first electrode 220 and the second electrode 240 are formed, foreign matter penetrates from the outside, thereby preventing a malfunction that changes the mechanical and electrical functions of the non-powered body temperature sensing apparatus.

Meanwhile, in order to measure an appropriate size of the ventilation hole 211, the ventilation hole 211 was manufactured in various sizes. Experiments were conducted. When the diameter of the ventilation hole 211 was 1.0 mm or more, the durability of the substrate became weak, The substrate may be damaged. In addition, when the diameter is 0.3 mm or less, evaporating water is formed in the vent hole 211, and the vent hole 211 is blocked, so that ventilation is not smooth. Therefore, it was found that the diameter of 0.3mm ~ 1.0mm is suitable for durability of the substrate and smooth ventilation. However, when the diameter is 1.0 mm, the substrate is damaged due to the movement of the body after about 24 hours after wearing the patch on the body.

Thus, when the diameter was set to 0.7 mm, the substrate was hardly damaged even if it was used for 24 hours or more. However, when used for more than 7 days, minute dust or the like in the air easily permeated and the vent hole 211 was clogged.

When the diameter was 0.5 mm, it was confirmed that the durability was maintained and the penetration of foreign matter was small and the discharge of sweat was smooth. Therefore, it has been confirmed that the vent hole 211 of the present invention has a diameter of 0.3 mm to 0.5 mm, which is most suitable for durability and smooth skin breathing.

A patch having a conventional temperature sensor is not smoothly ventilated and sweated when it is attached for a long period of time, so that a baby or a person sensitive to skin may suffer skin trouble when used. Therefore, according to the present invention, the ventilation holes 211 are drilled in the substrate 210 to smooth ventilation and sweat discharge at the patch attachment sites, thereby reducing the possibility that a child or a person sensitive to skin may cause problems with the skin even if the patch is attached for a long time .

Meanwhile, the first electrode 220 may be formed on the substrate 210 and wound in a coil shape to generate an induced electromotive force. The relative motion of the magnet and the coil induces a current in the coil, which is called the induced electromotive force. When a magnetic external device approaches the first electrode, a magnetic field is changed at the center of the first electrode wound around the first electrode, so that an induced electromotive force is generated and an induced current flows through the first electrode. The temperature sensor chip 10 can be operated by the induced current generated at this time. Therefore, the present invention can operate without a battery, so that it is thin and light compared with a conventional patch for detection, so that the wearer can keep the attachment state even when attached to the body, and there is no need to worry about mercury discharge of the battery, There are advantages.

Therefore, the following description will be made by dividing the non-powered body temperature sensing patch into a non-powered body temperature sensor 100 having a double-sided structure and a non-powered body temperature sensor 200 having a sectional structure.

9 is a diagram illustrating a configuration of an electroless body temperature sensing patch 300 including an electroless body temperature sensing apparatus 100 having a double-sided structure according to an embodiment of the present invention.

9, the non-powered body temperature sensing patch 300 including the non-powered body temperature sensing apparatus 100 according to an embodiment of the present invention includes a release film 310, a first adhesive layer 320 formed on the release film, , A substrate including a plurality of vent holes formed on the first adhesive layer (320), a temperature sensor chip mounted on the substrate, a first electrode in the form of a coil formed on the substrate, And a cover film (330) surrounding the non-powered body temperature sensing device (100). The non-powered body temperature sensing device (100) includes a first electrode Particularly, the first electrode 120 of the non-powered body temperature sensing device 100 may be formed on the first surface of the substrate 110, and the second electrode 130 may be formed on the second surface of the substrate 110. Here, if the first side refers to either side of the substrate 110, the second side refers to the opposite side.

The release film 310 serves to protect the first adhesive layer 320, which will be described later, which is attached to the body with a uniform thickness and is used for temporarily supporting the adhesive material or for protecting the adhesive layer, When the film 310 is peeled off, the first adhesive layer 320 to be described later is adhered to the body and the patch is worn.

The first adhesive layer 320 is attached to the body while the opposite surface is adhered to the non-powered body temperature sensor 100 to maintain the shape of the patch. At this time, a plurality of vent holes may be formed in the first adhesive layer 320. Therefore, since ventilation holes are formed on the surface directly adhered to the skin, ventilation and sweat discharge can be performed more effectively.

The non-powered body temperature sensing apparatus 100 is provided on the first adhesive layer 320 and has a double-sided structure, so that the first electrode 120 and the second electrode 130 are electrically connected to the substrate 110 As shown in Fig.

At this time, the substrate 110 may include a plurality of ventilation holes 111, which are perforated to allow ventilation and sweat discharge. The ventilation hole 111 may be formed in a region other than the portion where the first electrode 120 and the second electrode 130 are formed as shown in FIG. 2 for normal operation of the non-powered body temperature sensing apparatus. When the vent hole 111 is pierced in addition to the portion where the first electrode 120 and the second electrode 130 are formed, foreign matter may penetrate from the outside, thereby preventing a malfunction that changes the mechanical and electrical functions of the non-powered body temperature sensing apparatus.

When the diameter was 0.5 mm, it was confirmed that the durability was maintained and the penetration of foreign matter was small and the discharge of sweat was smooth. Therefore, it has been confirmed that the ventilation hole 111 of the present invention is most suitable for durability and smooth skin breathing with a diameter of 0.3 mm to 0.5 mm. A patch having a conventional temperature sensor is not smoothly ventilated and sweated when it is attached for a long period of time, so that a baby or a person sensitive to skin may suffer skin trouble when used. Therefore, according to the present invention, ventilation holes (111) are drilled in the substrate (110) to smooth ventilation and sweat discharge at the patch attachment sites, thereby reducing the possibility of infants or sensitive skin .

The cover film 330 is a film for protecting the non-powered body temperature sensing device 100 and surrounds the non-powered body temperature sensing device 100 to keep the non-powered body temperature sensing device 100 out of contact with the outside while maintaining mechanical and electrical functions , It is possible to prevent the foreign matter from penetrating and to prevent the characteristics of the temperature sensor chip 10 from being changed.

In addition, since the base film 340 is provided between the release film 310 and the first adhesive layer 320, the durability can be enhanced so that the patch does not tear or stretch even when pressed repeatedly for a long time, do. Or a second adhesive layer 350 on the cover film 330. The second adhesive layer 350 may be provided on the cover film 330,

In another embodiment of the present invention, the NFC coil may further include a communication unit for transmitting and receiving information to / from an external device, and the NFC coil to be described later transmits / receives the generated signal to / from an external device. At this time, the first electrode 120 is constituted by an NFC coil to generate an induction electromotive force to operate the temperature sensor chip 10 and to generate a signal for transmitting / receiving temperature information sensed by the temperature sensor chip 10 to / from an external device At this time, the second electrode 130 may be connected to the terminal of the mounted temperature sensor chip 10.

Because NFC can use both data reading and writing functions, there is no need for a reader that was previously required for the use of radio frequency identification (RFID). It is similar to existing short distance communication technology such as Bluetooth but it does not need to set up connection between devices like Bluetooth. Therefore, if an external device having the NFC function is contacted with the present invention, the connection is automatically made and the temperature can be measured quickly.

In another embodiment of the present invention, the non-powered body temperature sensing apparatus 100 further includes a via hole 140 passing through the substrate 110. The first electrode 120 is electrically connected to the first electrode 120 through the via hole 140, The second electrode 130 may be connected to the second electrode 130. At this time, an induced current or a received signal formed in the first electrode 120 can reach the temperature sensor chip 10 through the second electrode 130 connected to the first electrode 120 through the via hole 140. A transmission signal generated in the temperature sensor chip 10 can be transmitted to the first electrode 120 connected to the second electrode 130 through the via hole 140.

10 is a diagram illustrating a configuration of an electroless body temperature sensing patch 400 including an electroless body temperature sensing device 200 having a cross-sectional structure according to an embodiment of the present invention.

Referring to FIG. 10, the non-powered body temperature sensing patch 400 including the non-powered body temperature sensing device 200 according to an embodiment of the present invention includes a release film 410, a first adhesive layer 420 formed on the release film, A substrate including a plurality of perforated holes formed on the first adhesive layer 420, a temperature sensor chip mounted on the substrate, a first electrode in a coil shape formed on the substrate, And a cover film 430 surrounding the non-powered body temperature sensing device 200. The non-powered body temperature sensing device 200 may include a second electrode electrically connected to the non-powered body temperature sensing device 200, and a cover film 430 surrounding the non- Particularly, the first electrode 220 and the second electrode 240 of the non-powered body temperature sensing device 200 are formed on one side of the substrate 210, and the first electrode 220 and the second electrode 240 are formed between the first electrode 220 and the second electrode 240. And may further include an insulating layer 230.

The release film 410 serves to protect the first adhesive layer 420, which will be described later, which is attached to the body with a uniform thickness and is used for temporarily supporting a viscous component material or for protecting an adhesive layer, When the film 410 is detached, the first adhesive layer 420 to be described later is adhered to the body and the patch can be worn.

The first adhesive layer 420 is attached to the body while the opposite surface is bonded to the non-powered body temperature sensing device 200 to maintain the shape of the patch. At this time, a plurality of vent holes may be formed in the first adhesive layer 420. Therefore, since ventilation holes are formed on the surface directly adhered to the skin, ventilation and sweat discharge can be performed more effectively.

Since the non-powered body temperature sensing device 200 has a sectional structure, an insulating layer 230 is present between the first electrode 220 and the second electrode 240 to prevent the first and second electrodes 240 from short- do. Since the substrate 210 is formed on both sides of the substrate 210 with the interposition of the substrate 210, short-circuiting can be prevented without the insulating layer 230, and a thinner patch can be fabricated. It is preferable that the insulating layer 230 is located only at a portion where the first electrode 220 and the second electrode 240 are in contact with each other as shown in FIG. However, the second electrode 240 must be supplied with the induced electromotive force from the first electrode 220, so that one end of the first electrode 220 is connected to one end of the second electrode 240.

In this case, the substrate 210 may include a plurality of ventilation holes 211 pierced to allow ventilation and sweat discharge. The ventilation holes 211 may be formed in the first It is preferable that the electrode 220 and the second electrode 240 are formed in a region other than the region where the electrode 220 and the second electrode 240 are formed. When the vent hole 211 is punched in the portion where the first electrode 220 and the second electrode 240 are formed, foreign matter penetrates from the outside, thereby changing the mechanical and electrical functions of the non-powered body temperature sensing device, Because.

In the patch having the conventional temperature sensor, ventilation and sweat discharge are not smooth at the time of long time attachment. Therefore, when a baby or sensitive skin is used, the skin often has a problem. Therefore, according to the present invention, ventilation holes 211 are drilled in the substrate 210 to smooth ventilation and sweat discharge on the patch attachment sites, so that infants or sensitive skin do not cause problems on the skin even if the patches are attached for a long time.

The cover film 430 is a film for protecting the non-powered body temperature sensing device 200 and surrounds the upper portion of the non-powered body temperature sensing device 200 to block the non-powered body temperature sensing device 200 from the outside to maintain mechanical and electrical functions , It is possible to prevent the foreign matter from penetrating and to prevent the characteristics of the temperature sensor chip 10 from being changed.

In addition, since the base film 440 is provided between the release film 410 and the first adhesive layer 420, the durability can be enhanced so that the patch does not tear or stretch even when pressed repeatedly for a long time, do. Or a second adhesive layer 450 on the cover film 430. The second adhesive layer 450 may be provided on the cover film 430,
