Description

  The present invention relates to a mounting power generation module that is used by being mounted on a mounting target.

  Hereinafter, a conventional mounting power generation module will be described with reference to the drawings. In a conventional mounting power generation module, an antenna and a solar cell are formed on one surface of a double-sided flexible substrate. On the other hand, a sensor and a plurality of electronic components are directly mounted on the other surface of the flexible substrate to form a signal processing circuit. The entire mounting power generation module configured as described above is coated with resin. This coating with resin is provided so that all electronic components and solar cells mounted on the flexible substrate are completely covered.

  The mounting power generation module configured as described above is mounted on a mounting target, and a signal detected by the sensor is converted into a transmission signal by a signal processing circuit and transmitted to an external monitoring device via an antenna. At this time, the signal processing circuit is driven by the power supply voltage supplied from the solar battery. For example, such a power generation module for mounting is mounted on a human body or the like and continuously detects biological information or the like over a long period of time.

  As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

JP 2007-36988 A

  However, in the conventional mounting power generation module, it is desirable to increase the thickness of the flexible substrate in order to facilitate mounting of electronic components using a general-purpose mounting machine or the like. In addition, since the resin is formed with a thickness that allows the electronic component and the solar cell to be completely embedded with respect to the upper and lower sides of the flexible substrate, the entire thickness of the mounting power generation module increases. When the thickness is large in this way, it is easy to peel off from the mounting target. In addition, when the power generation module for mounting is thick when it is mounted on a human body, the wearer feels uncomfortable at the time of mounting, which hinders long-term continuous use.

  SUMMARY OF THE INVENTION The present invention solves this problem, and an object of the present invention is to provide a mounting power generation module that can be mounted and used continuously over a long period of time.

  In order to achieve this object, a flexible substrate, a solar cell formed on the upper surface of the substrate, a signal processing unit configured with a circuit driven by a power supply voltage from the solar cell, In the mounting power generation module that is mounted on a mounting target by a mounting member, the signal processing unit has rigidity, and includes a connection portion that electrically connects the solar cell and the circuit. It is smaller than the size. As a result, the intended purpose can be achieved.

  As described above, according to the present invention, the signal processing in which the base material having flexibility, the solar cell formed on the upper surface of the base material, and the circuit driven by the power supply voltage from the solar cell are configured. And a connecting part that electrically connects the solar cell and the circuit, and in the mounting power generation module that is mounted on the mounting target by a mounting member, the signal processing unit has rigidity, and The power generation module for mounting is smaller than the size of the substrate.

  As a result, the rigid part is only the signal processing part, and the area can be reduced, and the signal processing part in which the circuit is configured is connected to the base material via the connection part, so a thin base material is used. be able to. Therefore, it becomes difficult to peel off from the mounting target and can be used continuously for a long time. In addition, when wearing on the human body, it is possible to reduce the uncomfortable feeling at the time of wearing and the hindrance to the action, so that it can be used continuously for a long time. Furthermore, when such a power generation module for mounting is mounted on a human body with an adhesive or the like, the base material is not easily peeled off from the human body, so that it is not necessary to use a pressure-sensitive adhesive with strong adhesive strength. Accordingly, it is possible to use an adhesive having a weak adhesive force or to reduce the application area of the adhesive, so that fogging and the like hardly occur.

  Since the signal processing circuit has rigidity, the electronic components constituting the signal processing circuit can be easily mounted with a general-purpose mounting machine or the like. Therefore, it is possible to realize a mounting power generation module with very good productivity.

  Furthermore, since the solar cell is formed on a flexible substrate, the mounting power generation module can be securely mounted on the mounting target regardless of the shape or movement of the mounting target.

(Embodiment 1)
Hereinafter, the power generation module for mounting (hereinafter referred to as module 1) in the present embodiment will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a module according to the present embodiment, FIG. 2 is a bottom view thereof, and FIG. 3 is a top view thereof. The sensor device according to the present embodiment is attached to a measurement target, detects prescribed information, and transmits the detected information to a parent device (not shown). For this purpose, the module 1 has a module main body for transmitting the detected information, and a mounting member for mounting the module main body to a measurement target. In the sensor device according to the present embodiment, the adhesive 2 is applied as a mounting member on the side facing the measurement target of the module 1 (the lower surface side in FIG. 1). In the present embodiment, the adhesive 2 is provided on the lower surface of the module 1, but this is a size larger than that of the module 1, and a resin sheet coated with the adhesive 2 on the lower surface side may be used. . In this case, the resin sheet is attached to the measurement object so as to cover the module 1.

  Here, the measurement object in the sensor device of the present embodiment is a human body, and is affixed to the human body to detect various human body information. Therefore, when directly attaching to a human body or clothes, the release paper provided in advance on the surface of the adhesive 2 is peeled off, and the module 1 is attached directly with the adhesive 2. Also, for example, when the skin is weak and the adhesive 2 cannot be directly attached to the human body or clothing, the release paper is not peeled off (or a sensor device without the adhesive 2 is prepared in advance) A belt-shaped (or string-like) mounting tool is mounted on the sensor device, and the sensor device is mounted using this mounting tool.

  FIG. 4 is a circuit block diagram of the module 1 in the present embodiment. In FIG. 4, the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is simplified. Then, the circuit of the module 1 in this Embodiment is demonstrated in detail using FIG. The module 1 includes a signal processing unit 5, a solar battery 6 (used as an example of power generation means) that supplies a power supply voltage to the signal processing unit 5, and an output (or input / output or input) of the signal processing unit 5. And an antenna 7 connected to the. Here, the signal processing unit 5 includes a sensor 5a that detects human body information, a signal processing circuit 5b that converts information detected by the sensor 5a into a transmission signal, and the sensor 5a and the signal processing circuit 5b. And a driving circuit 5c for controlling the driving of the motor.

  The sensor 5a in the present embodiment is a temperature sensor that measures the body temperature of the human body, but is not limited thereto, and may be a sensor that detects other biological information such as a pulse or an action. Further, in the present embodiment, the human body information is detected by being attached to the human body, but the present invention is not limited to this, and other than the human body may be the measurement target. In this case, a sensor for detecting various information is appropriately provided according to each measurement object.

  Next, the configuration of the module 1 in the present embodiment will be specifically described with reference to FIGS. 1 to 3. The flexible substrate 8 (used as an example of a flexible base material) is a double-sided substrate in which a conductor layer is formed on both sides of a thin base film, and a flexible power generation means is provided on the upper surface side. Is formed. In the present embodiment, the power generation means is formed on the entire upper surface side of the flexible substrate 8 and the signal processing unit 5 is mounted on the lower surface side. In the present embodiment, the signal processing unit 5 is provided on the lower surface side of the flexible substrate 8, but the signal processing unit 5 may be mounted on the upper surface side of the flexible substrate 8. For example, a base film made of polyimide resin having a thickness of about 50 μm is used for the flexible substrate 8 in the present embodiment, and the thicknesses of the conductor layers on the front and back sides are each about 20 μm.

  FIG. 5 is an enlarged cross-sectional view of a main part of the solar cell in the present embodiment. In FIG. 1 and FIG. 5, the power generation means in the present embodiment is a dye-sensitized solar cell 6. This solar cell 6 includes an electrode 6a formed of a conductive film on the upper surface side of a flexible substrate 8, a transparent electrode 6b formed so as to face the electrode 6a with a gap 6d, and a flexible substrate 8 An insulating spacer 6c provided between the transparent electrode 6b and an electrolyte filled in a gap 6d surrounded by the electrode 6a, the transparent electrode 6b, and the spacer 6c. In the present embodiment, the electrolytic solution is used. However, any electrolyte may be used as long as it mediates the movement of electrons from the positive electrode to the negative electrode.

  Here, the transparent electrode 6b is made of a transparent conductive film 6f {ITO (indium tin oxide), zinc oxide or tin oxide on a flexible resin film 6e made of PET or the like by a method such as sputtering or vapor deposition. Etc.} are formed. The thickness of the resin film 6e in the present embodiment is 50 μm. As described above, the solar cell 6 is formed of the flexible thin flexible substrate 8 and the flexible thin resin film 6e. Therefore, the solar cell 6 itself has flexibility, Its flexibility is very high.

  In the present embodiment, a double-sided substrate is used as the flexible substrate 8 and the electrode 6a is formed of a copper foil. However, the transparent conductive film 6f may be formed on the non-formed side of the copper foil using a single-sided substrate. Of course, the flexible substrate 8 may be a multilayer substrate. The transparent conductive film 6f is connected to a connection pattern formed on the upper surface of the flexible substrate 8 by a conductive member such as a conductive adhesive. Then, each of the connection pattern and the electrode 6a is led out to the lower surface side of the flexible substrate 8 by a through hole or the like provided in the flexible substrate 8, and is connected to the signal processing circuit 5b through the connection portion 9. .

  Here, the spacer 6c is a thermosetting resin, and a gap 6d is formed by forming a hole having a hole in the center (b-shaped). Note that the spacer 6 c in the present embodiment is formed with a width of about 5 mm along the outer periphery of the flexible substrate 8. In the present embodiment, the dye-sensitized solar cell 6 is configured, but other types of solar cells and fuel cells may be used.

  On the other hand, a rigid signal processing unit 5 is connected to a central portion of the lower surface of the flexible substrate 8 via a connection unit 9. The connecting portion 9 is provided with a positive electrode connected to the positive electrode (electrode 6a side) of the solar cell 6 and a ground electrode connected to the negative electrode (transparent electrode 6b side). At this time, the size of the rigid signal processing unit 5 is set smaller than that of the flexible substrate 8 having flexibility. In this embodiment, in order to give rigidity to the signal processing unit 5, a glass substrate epoxy resin-based printed circuit board 10 is used, and a plurality of electronic components 11 are mounted on the lower surface of the printed circuit board 10 to perform signal processing. A circuit 5b is formed. In the present embodiment, the printed circuit board 10 uses a board having a thickness of about 0.3 mm, so that the height of the signal processing unit 5 is only 1 mm.

  Here, a connection land 9 a is provided on the upper surface of the printed circuit board 10. On the other hand, on the lower surface of the flexible substrate 8, a connection land 9b having substantially the same size and shape as the connection land 9a is formed at a position corresponding to the connection land 9a. The printed circuit board 10 is mounted at a position where the connection land 9a faces the connection land 9b, and the connection land 9a and the connection land 9b are connected by a connection member 9c or the like, so that the connection portion 9 is formed. In the present embodiment, solder is used for the connection member 9c, but the present invention is not limited to this, and any other material may be used as long as the material achieves electrical conductivity and mechanical connection. In FIG. 1, for convenience of explanation, the heights of the connection lands 9a, the connection lands 9b, and the connection members 9c are drawn larger than the actual ratio. Actually, since the distance between the flexible board 8 and the printed board 10 is about 0.2 mm, the dimension that the signal processing unit 5 protrudes from the flexible board 8 is only about 1.2 mm.

  With the above configuration, the signal processing unit 5 having a size smaller than that of the flexible substrate 8 and having rigidity is connected to the flexible substrate 8 having flexibility through the connection unit 9. Thereby, since the signal processing circuit 5b is configured on the rigid printed circuit board 10, it is not necessary to attach the electronic component 11 to the flexible circuit board 8. Therefore, the thickness of the flexible substrate 8 can be reduced, and the rigid portion is only the signal processing unit 5 (printed substrate 10), so that the rigid region can be reduced. Thereby, since flexibility in areas other than the printed circuit board 10 can be increased, the module 1 is unlikely to be peeled off from a mounting target such as a human body. Furthermore, the discomfort at the time of wearing and the hindrance to action can be reduced, and as a result, it can be worn and used continuously for a long time. Moreover, since it is hard to peel off from a human body, it is not necessary to use the adhesive 2 with strong adhesive force. Therefore, it is possible to use the pressure-sensitive adhesive 2 having a weak adhesive force, to reduce the application area of the pressure-sensitive adhesive 2, and to prevent the occurrence of fog and the like. In the case of the present embodiment, since the size of the signal processing unit 5 protruding from the flexible substrate 8 is also small, the wearer's discomfort can be further reduced.

  Since the signal processing unit 5 has rigidity, the electronic component 11 constituting the signal processing circuit 5b can be easily mounted with a general-purpose mounting machine or the like. Therefore, the module 1 with very good productivity can be realized. Furthermore, since the solar cell 6 is formed on the thin flexible substrate 8, the module 1 can be securely attached to the attachment object regardless of the shape of the attachment portion, movement, or the like.

  Here, the adhesive 2 is applied to a region excluding the place where the signal processing unit 5 is mounted on the lower surface of the flexible substrate 8. In the present embodiment, the periphery of the signal processing unit 5 is also the non-application part 2 a of the adhesive 2. Thereby, the signal processing unit 5 has a degree of freedom without being attached to the human body. Therefore, since it becomes difficult to obstruct the operation of the human body, the uncomfortable feeling of wearing can be reduced. Further, the signal processing unit 5 in the present embodiment is mounted at a position where the flexible substrate 8 protrudes in all four directions (vertical and horizontal directions in FIG. 2) of the signal processing unit 5. As a result, when the adhesive 2 is attached to the attachment target, the signal processing unit 5 is covered with the flexible substrate 8. Accordingly, it is possible to prevent entry of foreign matters from the outside. This is particularly useful when worn on the human body, and this configuration can prevent water and the like from entering the signal processing unit 5.

  Furthermore, since the signal processing unit 5 is provided on the lower surface side of the flexible substrate 8, the solar cell 6 can also be configured on the flexible substrate 8 above the signal processing unit 5. Therefore, the upper surface side of the flexible substrate 8 can be effectively used as the solar light receiving surface, and the flexible substrate 8 can be made smaller accordingly. Thereby, the low-priced module 1 can be realized and the uncomfortable feeling at the time of mounting can be further reduced.

  Thus, since the thickness of the flexible substrate 8 can be reduced, the uncomfortable feeling caused by the flexible substrate 8 can be reduced. However, since the signal processing unit 5 has rigidity, some people feel uncomfortable with a nervous person or the like. Therefore, in the present embodiment, the resin layer 12 in which the electronic component 11 is embedded is provided on the lower surface of the printed board 10. Thereby, since the electronic component 11 is covered with the resin, the flat surface of the resin layer 12 comes into contact with the skin, so that the uncomfortable feeling of mounting can be reduced. At the same time, sweat from the human body can be prevented from touching the signal processing circuit 5b, and malfunction of the signal processing circuit 5b is less likely to occur. Furthermore, corrosion of the conductor pattern on the printed circuit board 10 due to sweat or the like can be hardly caused. In the present embodiment, the resin layer 12 is further chamfered or rounded at a location where the lower surface and the side surface intersect. As a result, the corners do not touch the skin, so that the wearer's discomfort can be further reduced.

  FIG. 6 is a cross-sectional view when the module 1 according to the present embodiment is mounted on a mounting target. In FIG. 6, the same components as those in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is simplified. When the module 1 configured as described above is mounted on the mounting target, the portion of the adhesive 2 applied to the lower surface of the flexible substrate 8 is attached to the mounting target. At this time, since the signal processing unit 5 has a thickness, the flexible substrate 8 is bent at a corner 10 a where the upper surface of the signal processing unit 5 and the side surface of the printed circuit board 10 intersect. At this time, the distance of the gap 6d between the electrode 6a and the transparent electrode 6b is shortened, and in the worst case, the electrode 6a and the transparent electrode 6b are short-circuited. Therefore, in the present embodiment, in the gap 6d between the electrode 6a and the transparent electrode 6b, the insulating portion 6g is formed at a position corresponding to the side surface of the printed board 10 (on the extension line). Thereby, a short circuit between the electrode 6a and the transparent electrode 6b can be prevented.

  FIG. 7 is a cross-sectional view of the module in the second example. In the module 1 shown in FIG. 7, the signal processing unit 5 is divided into two. That is, each signal processing unit 5 is connected to the lower surface of the flexible substrate 8 by each connection unit 9. According to this, since the flexibility also occurs in the region 3 between the signal processing unit 5 and the signal processing unit 5, it is possible to further reduce the uncomfortable feeling at the time of wearing.

  FIG. 8 is a cross-sectional view of the module in the third example. In the module 1 shown in FIG. 8, an electronic component 11 is also mounted on the upper surface side of the printed circuit board 10, and the electronic component 11 on the upper surface side of the printed circuit board 10 is embedded with a resin layer 12a. In this case, chamfering or rounding is provided at a place where the signal processing unit 5 comes into contact with the flexible substrate 8 when mounted on the mounting target (the angle at which the upper surface of the resin layer 12a and the side surface of the resin layer 12a intersect). Thereby, since the bending of the flexible substrate 8 can be reduced, a short circuit between the electrode 6a and the transparent electrode 6b at the time of mounting can be prevented. In this case, the insulating portion 6g is provided on the extended line on the side surface of the resin layer 12a.

  FIG. 9 is a bottom view of the module in the fourth example. In the module 1 shown in FIG. 9, the flexible substrate 8 has a rectangular shape, the width in the short direction is substantially the same as the width of the signal processing unit 5, and the adhesive 2 is applied exclusively to both end portions in the longitudinal direction. .

  FIG. 10A is a cross-sectional view of the module in the fifth example, and FIG. 10B is a cross-sectional view of the module in the sixth example. In each of the above examples, the signal processing unit 5 is disposed on the lower side of the flexible substrate 8, but the signal processing unit 5 may be mounted on the upper surface of the flexible substrate 8 as shown in FIGS. 10 (a) and 10 (b). I do not care. That is, the printed circuit board 10 is connected to the upper surface side of the flexible substrate 8. In this case, the module 1 is attached to the human body so that the signal processing unit 5 faces upward. Thereby, the signal processing unit 5 does not directly touch the skin when worn on the human body. Furthermore, the flexible substrate 8 has flexibility at a place other than the connection portion 9. Accordingly, it is possible to further reduce the uncomfortable feeling at the time of wearing.

  In this case, the electrode 6 a and the connection land 9 b may be formed on the upper surface side of the flexible substrate 8, so that a single-sided substrate can be used for the flexible substrate 8. Therefore, a low-cost module 1 can be realized. Furthermore, since the flexibility of the solar cell portion can be further increased, the uncomfortable feeling at the time of mounting can be further reduced. In these fifth and seventh examples, the sensor 5a is preferably mounted on the lower surface of the printed circuit board 10. Thereby, the sensor 5a can detect the human body information without going through the printed circuit board 10 or the like. Furthermore, since the distance between the sensor 5a and the human body can be reduced, information on the human body can be detected with high accuracy.

  Note that a through-hole 21 larger than the outer periphery of the printed circuit board 10 is formed in the transparent electrode 6b in the fifth example at a position corresponding to the signal processing unit 5. Thereby, a recess 22 formed by the through hole 21 is formed on the flexible substrate 10, and a part of the printed circuit board 10 is accommodated in the recess 22. On the other hand, in the transparent electrode 6b in the sixth example, a through hole 24 is formed at a position corresponding to the connection portion 9 (connection land 9b), and a through hole 25 is formed at a position corresponding to the sensor 5a. Thereby, the thickness of the module 1 in the fifth example and the sixth example can be reduced, and the uncomfortable feeling at the time of mounting can be further reduced. Furthermore, the distance between the sensor 5a and the human body is also reduced, and the human body information can be detected with higher accuracy.

  FIG. 11 is a cross-sectional view of the module in the seventh example. As shown in FIG. 11, the signal processing unit 5 may be connected to the upper surface of the transparent electrode 6b. In this case as well, the module 1 is mounted on the human body with the signal processing unit 5 facing upward. Therefore, also in this case, the signal processing unit 5 does not touch the skin directly, and the uncomfortable feeling can be further reduced. However, in this case, a transparent electrode 6b having a conductive pattern such as a connection land 9b on the upper surface side and a transparent conductive film 6f formed on the lower surface is used. In the seventh example, the sensor 5a is preferably attached to the lower surface of the printed circuit board 10. Thereby, the distance between the sensor 5a and the human body can be reduced, and information on the human body can be detected with high accuracy. And in the case of this 7th example, since a solar cell can also be formed under the signal processing part 5, electric power generation amount can be enlarged. In particular, when the module 1 in the seventh example is mounted on an arm or the like, for example, the flexible substrate 8 is bent downward, whereby the gap 26 between the transparent electrode 6b and the signal processing unit 5 is increased. Therefore, since light easily enters the gap 26, the amount of power generation can be increased.

  Here, the flexible substrate 8 in the module 1 in the fifth to seventh examples is provided with a through hole 23 at a position corresponding to the sensor 5a. As a result, the distance between the sensor 5a and the human body can be further reduced, so that information on the human body can be detected with higher accuracy. In addition, since the sensor 5a can detect information without using the flexible substrate 8, it can further detect human body information with high accuracy. In addition, when the sensor 5a is a temperature sensor, there is no resin (flexible board | substrate 8) with small heat conduction between the sensor 5a and a human body, and a body temperature can be detected accurately. The configurations of the fifth to seventh examples have the same effect even when used for the first to fourth examples.

  In the module 1 in the above fifth to seventh examples, the distance between the lower surface of the printed circuit board 10 and the lower surface of the flexible substrate 8 increases in the order of the fifth example, the sixth example, and the seventh example. Become. Therefore, any of these configurations can be selected according to the height of the sensor 5a. That is, by using the configuration of the example according to the height of the sensor 5a, the distance between the sensor 5a and the human body can be reduced and can be detected with high accuracy. Conversely, the tip of the sensor 5a can be prevented from protruding from the lower surface of the flexible substrate 8, and the uncomfortable feeling during mounting can be reduced.

  The power generation module for mounting according to the present invention has an effect that it can be mounted and used continuously for a long period of time, and is particularly useful when used for a sensor device or the like that is mounted on a human body and detects biological information.
