Wearable material with ribbon soft light guide power supply

A wearable material, in particular, a belt-shaped soft light guiding optical power supply that is portable and environmentally friendly and energy-saving.

A wearable computer is a miniature electronic device that is currently worn on the body for browsing related information anytime and anywhere, such as a smart bracelet that senses various health indexes of the body, or a communication device (mobile phone or lithographic computer). One of the most important features of this type of next-generation 3C product is the continuity of the smart watch that is connected to the user for convenient operation. It maintains stable interaction between the communication device and the user. However, in order to improve the portability of the wearable device, Usually, its structural size is not too complicated and bloated, and the battery capacity is also limited (the battery capacity of the smart bracelet is about 100mAh, and the smart watch is about 400mAh), which leads to the battery life of the wearable device. ~2 days) is often tested. In order to effectively extend the standby and use time of the wearable device, some manufacturers began to use one side and store electricity. The two sides are developing in parallel, such as common solar charging, magnetic induction power supply and temperature difference power generation. Wait.

If the solar cell is made of polycrystalline germanium, the current market is mainly composed of hard polycrystalline germanium and soft polycrystalline germanium. Since the thickness of the solar cell itself is only about 100 micrometers (μm), the hard polycrystalline germanium is limited by inflexibility, resulting in its The mechanical impact resistance is far less than that of soft polycrystalline germanium; but conversely, the performance of hard polycrystalline germanium in terms of photoelectric conversion efficiency is significantly better than that of soft polycrystalline germanium, making both excellent and inferior and incapable of precise cutting.

At present, the common solar-charged wearing device mainly arranges solar cells parallel to the surface of the object to absorb light energy over a large area. However, if a hard polycrystalline crucible is to be used at the same time to obtain better photoelectric conversion efficiency, and the overall circuit of the wearable device is driven, it is forced to face the special use condition in which the wearing device is often flexed in daily life, once the wearing device is subjected to external force. Flexing, it is easy to cause damage to the structure of the rigid polycrystalline solar cell. If it is easy to damage, it will be difficult for the wearer to be accepted by the market. Conversely, the structural strength at the solar cell is always strengthened. In addition to forcing the flexibility and comfort of the wear device to decrease simultaneously, it is also possible to block the incidence of light incident, so that the power conversion efficiency is lowered.

In addition, many schoolchildren will once again enter the tutoring class after school, in order to get good results in many examinations, which will lead to the high moon in the moon when returning home. However, there are still many vehicles on the street at this moment, even if some operators provide A school bag with a reflective strap is attached to enhance the warning effect. However, the reflective strip must be illuminated by the light beam to remind the rear driving within a limited distance. It does not actively provide warnings and reduces the safety of the schoolchildren.

On the other hand, the current strap or strap is replaced by a strip-shaped soft light guide, so that when the light beam is irradiated to the strip-shaped soft light guide, the light beam can be refracted and scattered, incident on the photocell, absorbed and converted by the light source, and set in the photocell. The support base with high mechanical strength is additionally ensured that the photocell will not be easily damaged during sealing and use of the photovoltaic cell, reducing the production cost and increasing the product yield. In addition, the extension of the use of this structure is extended to the strap of the schoolbag, through the light According to the mechanism of electricity storage, the schoolbags can spontaneously emit light when they return home at night, proactively alerting the rear driving to increase alertness to ensure the safety of school children.

Figure 5 is a side elevational cross-sectional view of a third preferred embodiment of the present invention for showing the connection relationship of its internal structure.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. In the examples, the same elements will be denoted by like reference numerals.

A first preferred embodiment of the present invention, as shown in FIG. 1 to FIG. 3, is exemplified by a smart watch having a body 1 and a strip-shaped soft light guiding power supply 2, which is referred to herein for convenience of explanation. The body 1 is a watch core made of circuit components such as a circuit board and a wafer, and the strip-shaped flexible light guide optical power supply 2 includes two photovoltaic cells 22 having a thickness of about 100 μm, and in order to prevent the photovoltaic cell 22 from being sealed. In the process of damage, in this example, a layer of glue is applied to the support base 24 to pre-press the photocell 22 into the protective recess 240 of the support base 24, thereby providing conductive and uniform mechanical support behind the photocell 22.

In this example, the photocell 22 is formed with two conductive contacts 222 of the positive and negative electrodes on the guiding surface 220, and after mounting, is electrically insulated from each other to the two terminal electrodes 242 of the supporting base 24, and simultaneously The light incident surface 224 of the photovoltaic cell 22 is exposed to obtain sufficient light energy. It should be noted here that the foregoing uniform support does not limit the assembly relationship between the support base and the photovoltaic cell, and must be completely attached; as long as the support base is in the process of photocell sealing fabrication and future use, the photovoltaic cell can be provided from the rear side. The average support throughout the surface to properly protect the structural integrity of the photovoltaic cell is the uniform support referred to in this case, and does not limit, for example, that the glue must be full.

The support base 24 is further formed with a set of output ports 244 of the electrical connection ports 10 of the power supply connection body 1, whereby the light energy converted by the photocell 22 is output to the body 1, and the input power is converted by voltage. The device 12 adjusts the voltage required for the operation of the body 1 or stores the electrical energy to be output again, and optionally supplies the power to the power storage device 14 that is interpreted as a super capacitor to store the converted electrical energy, or directly to the example. A low-energy device 16 that is interpreted as a watch core assembly for displaying predetermined information such as current time, missed calls, and map navigation, thereby forming a complete electrical circuit.

In this example, the foregoing watch core assembly includes a circuit component such as an oscillator, a microprocessor, and a memory disposed on the circuit board, and a touch display panel; on the other hand, the fabrication of the assembly guide is performed. After the process is completed, the main body 1 and the support base 24 on which the photovoltaic cell 22 is placed are placed together in the accommodating case 3, and a through opening 30 is formed at the light incident surface 224 of the corresponding photocell 22 to prevent the photocell 22 from being obstructed. Light absorption efficiency.

Since the light absorption angle of the light incident surface 224 of the photovoltaic cell 22 in the present invention has been changed with the installation position of the photovoltaic cell 22, the surface of the surface of the surface of the watchband is laterally facing, and the light energy irradiated to the surface of the watchband is not easily directly incident on the photovoltaic cell 22, and the light is Absorption efficiency will be significantly discounted. In order to effectively maintain the efficiency of use of the photovoltaic cell 22, the strip-shaped soft light guide optical power supply 2 in this example further comprises two strip-shaped soft light guides 26 which are formed by PDMS (Polydimethylsiloxane) material, each of which is formed. Each of the strips of flexible light guides 26 has an exposed face 262 that extends along a longitudinal direction 260 and that is a curved relief surface.

On the opposite side of the exposed face 262, that is, the side that is in contact with the skin is the applicator face 264, and the exposed face 262 and the applicator face 264 have an assembled side 266 for connecting to each other and laterally intersecting the long direction 260, and to avoid The photocell 22 is directly exposed to the air and is damaged by moisture intrusion. In the process of assembly, the housing 3 in which the body 1, the photocell 22 and the support base 24 are placed is placed in a mold, and the technique of injection molding is adopted. The liquid PDMS material is filled into the mold and gradually filled into the through opening 30 of the accommodating case 3, and finally solidified into a soft photoconductive material, so that the photocell 22 placed in the support pedestal 24 is close to the exposed surface 262. At a predetermined angle of 90 degrees, the sealing joint is disposed on the assembled side 266.

The sealing joint here means that the interface between the strip-shaped soft light guide and the photovoltaic cell does not generate any air bubbles, not only to maintain the structural strength of the photovoltaic cell, but also to avoid photoelectricity. The pool is oxidized and damaged; on the other hand, if the exposed surface 262 of the strip-shaped soft light guide 26 is used alone to refract or scatter the light beam, it is not sufficient to improve the utilization efficiency of the light beam. Therefore, the covering surface 264 of the present example is also formed with a layer of reflection. The coefficient is higher than the reflective layer 268 of the exposed surface 262, so that the light beam does not directly pass through the bonding surface 264 after being irradiated to the exposed surface 262, and is reflected again to increase the utilization efficiency of the light beam. Of course, as can be easily understood by those skilled in the art, the strip-shaped soft light guide in this example does not contain any impurities or bubbles, but even if the bubbles are intentionally formed or even doped with some impurities, the incident light beam can generate additional refraction. Or scattering, improving the efficiency of photon absorption and conversion by photocells, are not excluded from the case, but belong to a simple transformation of structure.

The second preferred embodiment of the present invention is modified by a smart bracelet. Please refer to FIG. 4. The support base 24' in this example is a circuit board made of ceramic material, and the photocell 22' is The SMT (Surface Mount Technology) method is directly soldered on the support base 24', and is electrically connected as the circuit-integrated body 1' as in the previous embodiment, in this example. The two end electrodes of the photocell 22' are respectively formed on the light receiving surface and the guiding surface, and the end electrodes on the light receiving surface are connected to the output crucible on the supporting base by wire bonding, and then the electric energy is transmitted. The mechanism is the same as that of the previous embodiment, and will not be described here. In addition, the manufacturing method is to put the welded body 1', the photocell 22' and the supporting base 24' into a mold together, and then completely embed the above structure by a liquid plastic slurry, and form the above-mentioned embedded forming technology. A one-piece, seamless, smart bracelet. Therefore, the exposed surface, the bonding surface and the assembled side of the previous embodiment will form a base portion 261' in this example, and the portion covering the body 1', the photovoltaic cell 22' and the support base 24' will be referred to as a covered portion. 263'.

For the third preferred embodiment of the present example, please refer to FIG. 5. The body 1" of this example is changed to the strap of the schoolbag, and the low-energy device 16" can be regarded as a wattage of about 5 watts. The light-emitting diode element, the electrical circuit connection of this example is doped with a small amount of conductive powder in the plastic for making the support base, and then burned on the support base by the technical process of LDS (Laser Direct Structuring). A plurality of traces are exposed to expose the conductive particles buried in the support pedestal, and additional plating can be performed to thicken the circuit, thereby forming a complete conductive circuit, so that the electric energy converted by the photocell (not labeled) is transmitted to the low-energy device. 16", reducing the complexity of the structure and keeping the weight of the bag to the existing use, reducing the burden on the schoolchildren. In this case, the photocell can be easily absorbed and converted by the daily routine during the daytime, and stored by the power storage device (not labeled). The converted electric energy, and in order to prevent the low-energy device 16" from autonomously emitting light without operating, therefore, in this example, an additional start switch 4" is additionally provided to open and close the low-energy device 16" according to the user's usage habits. Prevent the power from running out too quickly, and there is no electricity to operate when it needs to be started. Of course, as will be readily apparent to those skilled in the art, even if the preformed conductive plastic is embedded as a conductive path by injection molding the plastic paste, the technical features of the present example are not affected.

In summary, the wearable article with the strip-shaped soft light guiding optical power supply disclosed in the present invention adjusts the position of the easily damaged photocell to the side of the wearing device from the surface placed on the wearing device. It can be used in conjunction with the wearer's often flexed state of use, thereby greatly increasing the service life of the photocells enclosed in the wearable device; at the same time, the strip-shaped soft light guide is used to replace the popular strap or strap, so that the beam is irradiated to the strip-shaped soft light guide. At the same time, the photon can be absorbed and converted by the photocell by means of refraction and scattering; and the support of the photocell is additionally provided with a support base with high mechanical strength to provide uniform support, so that in the process of sealing and future use of the photovoltaic cell, Easy to break due to external forces, reduce production costs and increase product yield. In addition, the application of this structure is extended to the strap of the schoolchildren's schoolbag. Through the mechanism of light storage, the schoolbag can spontaneously emit light when the school child returns home at night, proactively warning the rear driving. Be alert to ensure the safety of school children.
