[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0022] Before introducing the terminal and accessory provided in the embodiments of this disclosure, the technical problems involved in the relevant scenario are first introduced. As smartwatches become increasingly intelligent, they have enormous application potential in personalized healthcare and health monitoring. However, with the continuous improvement of their functions and the expansion of application scenarios, their power consumption is also increasing. The built-in battery of the watch not only has disadvantages such as large size, high rigidity, and significant safety hazards, but also requires external charging or battery replacement. Therefore, there are problems of high charging frequency and short battery life.

[0023] In relevant scenarios, watches are powered by energy harvesting devices, such as solar panels. However, in conditions like cloudy days, indoor environments, and nighttime, solar panels cannot provide stable power. Another approach is thermoelectric power generation, but watches powered by thermoelectric generators require a significant temperature gradient, again resulting in unstable power. Finally, kinetic energy generation is also an option, but these watches require wearer movement to provide continuous power, again leading to inconsistent power delivery.

[0024] All of the aforementioned self-powered methods suffer from the inability to provide stable power, making it difficult to use the watch continuously in daily life. In related scenarios, there are also solutions that integrate multiple energy-collecting self-powered methods. However, the integrated energy collection device results in a bulky structure that only considers the stacking of different energy collection methods without effectively utilizing the mutual benefits between different energy sources. This leads to poor integration and low energy density.

[0025] Figure 1 This is a schematic diagram illustrating the structure of a terminal according to an exemplary embodiment. The terminal can be, for example, a smartphone, tablet, or wearable device, wherein the wearable device can include headphones, a watch, smart glasses, etc. Figure 1 As shown, the terminal includes a gating switch circuit and multiple power generation devices, each of which generates power in a different manner and is connected to the gating switch circuit.

[0026] In this embodiment of the disclosure, the power generation device can generate electricity through any of the following methods: solar energy, kinetic energy, and thermoelectricity. Solar energy power generation uses solar panels to convert solar energy into electrical energy; kinetic energy power generation utilizes the kinetic energy generated by the swinging of the user's arms or legs while walking or running, such as the kinetic energy generated by the swinging of the user's arms, which is then converted into electrical energy through a gyroscope structure, a micro-generator, or other devices; thermoelectricity power generation utilizes the temperature difference between the user's skin and other objects with relatively low temperatures to drive power generation.

[0027] The gating switch circuit is used to partially or completely connect the power generation device and the load in the terminal. The selective switching circuit can selectively turn the power between the power generation device and the energy fusion unit on or off according to the demand and output power. It allows one or more power generation devices to be selected from multiple power generation devices to connect to the energy fusion unit, realizing the distribution or conversion of electrical energy.

[0028] For example, when the load's power demand is greater than or equal to the energy fusion unit's output power, all power generation devices are connected to the energy fusion unit, thus all power generation devices supply power to the load. When the load's power demand is less than the energy fusion unit's output power, only some power generation devices are connected to the energy fusion unit, thus only some power generation devices supply power to the load. For instance, when the load's power demand is less than the energy fusion unit's output power, solar power generation devices are connected to the energy fusion unit, thus supplying power to the load through solar power generation.

[0029] Multiple power generation devices are used to collaboratively supply power to the load based on the gating switch circuit being connected to the load in the terminal.

[0030] In this context, collaborative power supply involves multiple power generation devices working together to meet the power demands of the load. Furthermore, powering the load in the terminal can be done directly, such as by supplying power to the display screen, or by having the power generation devices charge the battery in the terminal. The battery stores the electrical energy generated by the power generation devices and discharges it to the load when needed.

[0031] The load can include all the electrical components of the terminal, such as the terminal's screen, image processor, central processing unit, and energy storage device, which can be understood as a battery.

[0032] Taking a terminal comprising both solar and kinetic power generation devices as an example, when the wearer is highly active, the kinetic power generation device can provide more power output, while the solar power generation device provides the surplus power, thus meeting the terminal's power needs. When the wearer is indoors or outdoors in ample sunlight, the solar power generation device can provide more power output, while the kinetic power generation device provides the surplus power. A power management system can be configured in the terminal, which can switch or combine the use of these two power generation devices according to their power generation conditions to ensure the normal operation of the terminal. For example, at night or in dimly lit indoor environments, the kinetic power generation device can be the primary power source; while during the day or outdoors in ample sunlight, the solar power generation device can provide more power support.

[0033] In this embodiment, the terminal includes multiple power generation devices, each with a different power generation method. These devices work together to supply power to the loads within the terminal. By integrating power generation devices with multiple power generation methods, the terminal can collaboratively supply power to its loads. This allows for flexible selection and combination of power generation methods, improving overall energy utilization efficiency, enhancing the terminal's self-sufficiency, and reducing dependence on external power sources. Furthermore, the collaborative power generation of multiple methods ensures that even if one method fails due to environmental factors or malfunctions, other power generation devices can continue operating to supply power to the loads. The redundancy between the devices effectively utilizes the mutual benefits of different power generation devices, increasing the terminal's integration and energy density in terms of power generation. This also significantly improves the stability and reliability of power supply to the terminal, ensuring continuous operation in various environments.

[0034] In some possible implementations, the plurality of power generation devices include a first power generation device and a second power generation device. The first power generation device includes a first power generation unit and a first power converter. The voltage output terminal of the second power generation device is connected to the start-up input terminal of the first power converter. The output voltage of the first power generation unit is less than the start-up voltage of the first power converter, and the output voltage of the second power generation device is greater than or equal to the start-up voltage of the first power converter.

[0035] In this embodiment, the first power generation unit is responsible for generating electrical energy, but its output voltage is too low to directly meet the power requirements of the smartwatch. Therefore, a first power converter is needed to boost the voltage to a suitable level. However, the first power converter requires a certain startup voltage to begin operation.

[0036] In this embodiment of the disclosure, the first power generation device can be a thermoelectric generator. Usually, the wearer's body temperature is not much different from the ambient temperature, and the voltage of the thermoelectric generator is low. Therefore, it is difficult to start the first power converter through the output voltage of the thermoelectric generator. Therefore, the starting voltage of the first power converter can be provided by the second power generation device.

[0037] In this embodiment, the second power generation device is a high-power, high-voltage power generation device. For example, the second power generation device can be a solar power generation unit (such as a solar panel), with a high output voltage (e.g., 3V), which is greater than the startup voltage of the first power converter. Under sufficient sunlight, the second power generation device can provide the power required for the startup of the first power converter and simultaneously use the provided power to supply the load of the terminal. Alternatively, the second power generation device can be a power generation unit (such as a solar panel), with a high output voltage (e.g., 3V), which is greater than the startup voltage of the first power converter. Under sufficient sunlight, the second power generation device can provide the power required for the startup of the first power converter and simultaneously use the provided power to supply the load of the terminal.

[0038] In this embodiment of the present disclosure, when the first power generation device starts generating electricity, the first converter starts working based on the starting voltage provided by the second power generation device. In this way, the first power generation device and the second power generation device can realize system power generation and supply complex power to the terminal.

[0039] See also some possible implementations. Figure 3 As shown, the terminal further includes a control circuit, the control circuit being used for: The output power of the second power generation device is used as the starting power of the first power converter. The power generation device includes the first power generation device and the second power generation device. In this embodiment of the disclosure, in situations such as the initial startup phase of the terminal, or when the first power generation device is a thermoelectric generator, and the output power of the thermoelectric generator is insufficient to meet the startup power requirements of its first power converter, thus preventing it from starting automatically, a power generation device or a solar power generation device can be used as a second power generation device. The output power of the power generation device or the solar power generation device can then be used as the startup power for the first power converter of the thermoelectric generator. The power converter is responsible for the initial adjustment and stabilization of the power generated by the thermoelectric generator.

[0040] Alternatively, when the first power generation device is a motor power generation device, if the vibratory generator cannot start on its own due to insufficient motion, a solar power generation device can be used as a second power generation device. The output electrical energy generated by the solar power generation device can then be used to start the first power converter of the motor power generation device. The power converter is responsible for converting the mechanical energy generated by the vibratory generator into electrical energy and for performing initial adjustments and stabilization.

[0041] The output power of the first power generation unit of the first power generation device is converted by the first power converter; In this embodiment of the disclosure, after the first power converter is started, it begins to convert the electrical energy generated by the first power generation device. For example, the conversion process may include increasing or decreasing the voltage, adjusting the current, and stabilizing the electrical energy to ensure that the generated electrical energy meets the power supply requirements of the terminal.

[0042] For example, when the thermoelectric generator is activated, the first power converter boosts the output voltage of the thermoelectric generator, improving its stability. Similarly, when the wearer begins to move, causing the internal vibration generator of the watch to vibrate, the first power converter starts working, converting the mechanical vibration into electrical energy. This electrical energy may initially be unstable, with fluctuating voltage and current. Through the adjustment of the first power converter, this unstable electrical energy is converted into stable direct current, with voltage and current matching the power supply requirements of the watch's internal electronic components.

[0043] The output power of the second power generation device and the output power converted by the first power converter are output to the load.

[0044] In this embodiment of the present disclosure, based on the predicted power demand and the operating status of the power generation device, the power generated by the second power generation device and the power generated after conversion by the first power converter are selected to be output to the load in the terminal.

[0045] For example, based on predicted electricity demand and the operating status of the power generation unit, the system selects to output the electricity generated by the power generation unit and the electricity generated by the thermoelectric generator (after conversion by a first power converter) to the terminal load. This process may involve the merging, distribution, and regulation of electricity to ensure that the terminal load receives a stable and sufficient power supply.

[0046] In some possible implementations, the terminal further includes an energy fusion unit, in which multiple power generation devices are connected to the energy fusion unit via the gating switch circuit. The energy fusion unit is used to merge the power input from the power generation devices connected to the load and provide stable power to the load of the terminal.

[0047] In this embodiment, the energy fusion unit may be configured with the same number of interface circuits as the power generation devices. Each power generation device is connected to one interface circuit, which can connect the output voltage provided by the power generation device to the collaborative management circuit of the energy fusion unit. The energy fusion unit performs regulated power output when the load changes or the state of the energy storage capacitor changes.

[0048] In this embodiment of the disclosure, the interface circuit corresponding to the power generation device for each power generation method is different. For example, see [link to relevant documentation]. Figure 2 As shown, interface circuit C corresponding to the solar power generation device can be composed of a buck-boost converter incorporating the MPPT (Maximum Power Point Tracking) algorithm; interface circuit B corresponding to the thermoelectric power generation device can be composed of a boost converter incorporating the MPPT algorithm; and interface circuit A corresponding to the power generation device can be composed of an AC-DC converter. The module executing the MPPT algorithm can employ a low-power MCU (Micro-controller Unit) and a low-power energy management module.

[0049] Furthermore, the interface circuit corresponding to the thermoelectric generator can be a DC-DC converter with MPPT function. The DC-DC converter can be a single-inductor Boost structure, operating in discontinuous conduction mode (DCM) to reduce the internal power consumption of the DC-DC converter. The interface circuit corresponding to the power generator can be a self-starting AC-DC converter. The output terminal of the DC-DC converter of the interface circuit corresponding to the thermoelectric generator is connected to the AC-DC converter of the interface circuit corresponding to the power generator. Thus, the output voltage of the DC-DC converter of the interface circuit corresponding to the thermoelectric generator can be output to the AC-DC converter of the interface circuit corresponding to the power generator. The AC-DC converter of the interface circuit of the power generator will merge the power output of the power generator and the power output of the DC-DC converter of the interface circuit corresponding to the thermoelectric generator, thereby achieving further fusion of the power generated by the two generators.

[0050] In some possible implementations, the gating switch circuit is used for: Based on the electrical energy demand of the load and the output electrical energy of the energy fusion unit, select some or all of the power generation devices to be connected to the energy fusion unit.

[0051] In this embodiment, the power demand of the load can be continuously monitored, such as screen brightness, sensor activity, and communication module status. Simultaneously, the output power of the energy fusion unit is also monitored, i.e., the total power that can be provided by fusing the output power generated by different power generation devices. Based on this information, some or all of the power generation devices are selected to be connected to the energy fusion unit to ensure that the load receives sufficient power supply, while avoiding the generation of excessive power that could damage the load or generate unnecessary power, thus increasing the power generation burden on the power generation devices.

[0052] The above-mentioned technical solution enables multiple power generation devices to work together to meet the power demand of the terminal, while achieving efficient energy utilization and stable operation of the terminal. The strategy of coordinated power generation and supply not only improves the energy utilization efficiency of the terminal, but also enhances its ability to adapt to different environments and usage scenarios.

[0053] See also the following for some possible implementations. Figure 2 and 3 As shown, the terminal also includes an energy storage device. The input end of the energy storage device and the power supply end of the load in the terminal are both connected to the output end of the energy fusion unit. The energy storage device is connected to the load of the terminal.

[0054] The energy fusion unit is used to supply power to the load and charge the energy storage device when the output power of the energy fusion unit is greater than the power demand of the load.

[0055] The energy storage device is used to supply power to the load together with the energy fusion unit when the output power of the energy fusion unit is less than the power demand of the load.

[0056] In this embodiment of the disclosure, electrical energy can be stored in an energy storage device when energy is abundant, and the stored energy can be released when energy demand is high or low to meet load requirements. The energy storage device can be a supercapacitor, thereby increasing the amount of electricity it can store.

[0057] In this embodiment, when the output power of the energy fusion unit exceeds the power demand of the load, the load's power demand is met first, and the excess power is transferred to the energy storage device for charging. This ensures efficient energy utilization and storage. When the output power of the energy fusion unit is less than the load's power demand, the energy storage device releases its stored power to supply power to the load together with the energy fusion unit. This ensures that the load can still receive a stable power supply even when energy is insufficient.

[0058] Among them, see Figure 3 As shown, the energy fusion unit includes an overvoltage protection unit. The energy fusion unit is connected to the energy storage device through the overvoltage protection unit. When the energy storage device reaches its maximum storage capacity and the power output supplied to the terminal exceeds the power demand, the overvoltage protection unit, according to a preset control strategy, controls a selection switch circuit to stop power generation from one or more of the power generation devices. The overvoltage protection unit automatically stops charging the charging capacitor by setting a charging threshold to prevent overcharging and protect the energy storage capacitor.

[0059] Furthermore, the selection switch can be used for selection control based on the electrical energy stored in the energy storage device. For example, if, based on the load's demand and the energy fusion unit's output, the output of the energy fusion unit is determined to be greater than the demand, the circuit between the energy fusion unit and the energy storage device can be opened first, providing the power to the terminal load to meet the demand, while the remaining output power charges the energy storage device. Further, when the energy storage device reaches its maximum storage capacity, with the goal of output power equal to demand power, some power generation devices are selected to be connected to the energy fusion unit. Further still, if all power generation devices are connected to the energy fusion unit, and the output power is still less than the demand, the circuit between the energy storage device and the load is opened, at which point the load is powered together by the energy storage device and the energy fusion unit.

[0060] In some possible implementations, the terminal further includes a first fusion unit and a second fusion unit, wherein the output terminals of at least some of the power generation devices are connected to the input terminal of the first fusion unit through the gating switch circuit, and the output terminals of the first fusion unit and the output terminals of the other power generation devices are connected to the second fusion unit through the gating switch circuit.

[0061] Among them, the other power generation devices are those whose output terminals are not connected to the input terminals of the first fusion unit.

[0062] It can be explained that the power generation device connected to the input terminal of the first fusion unit can be a power generation device whose voltage is greatly affected by the environment and the usage scenario of the terminal. Through multiple fusions in batches, a stable power can be formed in the second fusion unit.

[0063] For example, the input terminal of the first fusion unit is connected to the second output terminal of the power generation device and the first output terminal of the thermoelectric generator, respectively. The first fusion unit merges the power generated by the power generation device and the thermoelectric generator and provides the merged power to the second fusion unit.

[0064] Furthermore, the input terminal of the second fusion unit is connected to the first output terminal of the solar power generation device and the output terminal of the first fusion unit, respectively. The output terminal of the second fusion unit is connected to the power input terminal of the terminal load. The second fusion unit merges the power provided by the first fusion unit and the solar power generation device, and provides the merged power to the terminal load.

[0065] The first fusion unit uses the electricity provided by the power generation device and the thermoelectric generator as charging power to charge the capacitor, and then provides the charged power to the second fusion unit. For example, the first fusion device includes a charging capacitor. The first fusion unit uses the electricity provided by the power generation device and the thermoelectric generator as charging power to charge the capacitor, and then releases the stored power from the charging capacitor to the second fusion unit. The first fusion unit also includes a detection unit. The charging capacitor is connected to the second fusion unit through the detection unit. When the detection unit detects that the capacitance value of the charging capacitor has reached its peak value, it releases the stored power from the charging capacitor to the second fusion unit.

[0066] Furthermore, the second fusion unit uses the power provided by the first fusion unit and the solar power generation device as charging power to charge the device, and then provides the charged power to the terminal load. For example, the second fusion unit includes a charging inductor, which uses the power provided by the first fusion unit and the solar power generation device as charging power to charge the inductor, and after the inductor is fully charged, releases the power stored in the charging inductor to the terminal load.

[0067] See Figure 3 As shown, the terminal can detect the pulsating DC signal of the charging capacitor through the peak detection unit. When the signal reaches its peak value, the charging capacitor is connected to the energy fusion unit. The energy harvesting efficiency of the solar power generation device can be optimized through the algorithm execution unit. The algorithm execution unit can employ a low-power MCU and / or a low-power energy management chip integrating an MPPT controller.

[0068] In this way, by merging the power supplied by the power generation devices in batches, the stability of the power supplied to the end load can be improved. At the same time, by merging the power supplied by all power generation devices through, for example, charging inductors, energy density can be improved and current stabilization can be achieved.

[0069] In some possible implementations, the terminal is a wrist-worn wearable terminal, which includes: The terminal body and the wristband connected to the terminal body.

[0070] In this embodiment of the disclosure, see Figure 4 As shown, the wrist-worn wearable terminal is a smartwatch. The wristband of the wrist-worn wearable terminal may include an upper strap and a lower strap, and the upper and lower straps may have the same structure. The upper strap may include an outer side 101 and an inner side 102, and the lower strap may include an outer side 201 and an inner side 202.

[0071] The plurality of power generation devices include solar power generation devices and thermoelectric power generation devices.

[0072] The outer sides of the upper and lower watch straps form a heat dissipation layer 10, and a connection structure for a solar power generation device 11 and a thermoelectric power generation device 13 is configured between the outer and inner sides of the upper watch strap. For example... Figure 4 As shown, the thermoelectric power generation device 13 may include an upper thermoelectric power generation component 301 disposed on the upper surface band and a lower thermoelectric power generation component 302 disposed on the lower surface band, and the solar power generation device 11 may include an upper solar power generation component 401 disposed on the upper surface band and a lower solar power generation component 402 disposed on the lower surface band.

[0073] The wristband has at least one solar panel of the solar power generation device on its outer side and at least one thermoelectric semiconductor component of the thermoelectric power generation device on its inner side.

[0074] In this embodiment, a single or multiple flexible photovoltaic cells are encapsulated on the solar panel. These photovoltaic cells can be rationally distributed according to the light intensity information of the wrist and electrically connected to form a photovoltaic cell array. Since the sides of the wrist receive more light and the inner wrist pulse area receives less, high-intensity photovoltaic cells can be placed in the areas of the wristband that receive more light, while low-intensity photovoltaic cells can be placed in the areas that receive less light. This improves both economic efficiency and power generation performance and efficiency.

[0075] In this embodiment, the material, number, and connection method of the batteries in the solar panel are not limited and can be adjusted according to actual conditions. For example, multiple solar panels can be arranged in a parallel array. Different solar panels are rationally distributed according to the light intensity information of the wrist. After each solar panel is connected to a diode, the positive and negative terminals are connected to form a parallel array. The solar panel 11 can transmit electrical energy to the collaborative management circuit for output regulation through the interface circuit.

[0076] In some possible implementations, the outer array of the wristband is provided with a plurality of solar panels of the solar power generation device, the solar panels being connected in parallel via Schottky diodes.

[0077] In this embodiment, the battery material in the solar panel can be a perovskite battery or other material that balances flexibility and conversion efficiency. To prevent reverse current and minimize diode voltage drop, the diode connected to each solar panel can be a Schottky diode.

[0078] In this embodiment of the disclosure, see Figure 5 As shown, the thermoelectric power generation device 13 may include pairs of thermoelectric semiconductor components. These components may employ rigid thermoelectric semiconductor grains or materials such as bismuth telluride, which possess high thermoelectric figure of merit at room temperature. The thermoelectric semiconductors are connected by silver-coated copper wires to improve thermal conductivity and enhance power generation. The positive and negative electrodes of the thermoelectric power generation device adopt an island-bridge structure, allowing for direct connection of flexible electrodes, facilitating integration into the energy fusion unit and enhancing the flexibility and strength of the connection.

[0079] The rigid thermoelectric semiconductor grains can be electrically connected according to a P-type-N-type-P-type-N-type semiconductor structure. A P-type-N-type connection constitutes a pair of thermoelectric semiconductors. The hot ends of the paired thermoelectric semiconductors can directly contact the skin, meaning the thermoelectric semiconductor assembly uses the wearer's skin temperature as a heat source and the portion in contact with the backplate of the solar panel as a cold end. The hot and cold ends can form a heat conduction mechanism, which the thermoelectric power generation device relies on to generate electricity. The positive electrode 1301 and negative electrode 1302 of the thermoelectric power generation device are respectively connected to the first power converter.

[0080] The thermoelectric generator can be encapsulated with a flexible PDMS film, ensuring both power generation efficiency and biocompatibility to avoid allergic reactions and improve wearability. Because the thermoelectric generator has a low DC voltage output, it can be combined with the interface circuit of an MPPT-functional DC-DC converter to simultaneously output electrical energy. The first power converter can be a DC-DC converter with a single-inductor Boost structure, operating in intermittent conduction mode to reduce internal power consumption.

[0081] In this embodiment, the cold end of the thermoelectric semiconductor is directly attached to the back plate of the solar panel, which can reduce the contact thermal resistance between the two and improve the effective heat conduction between the back plate of the solar panel and the thermoelectric semiconductor, thereby improving the thermal difference power generation efficiency while ensuring the power generation effect of the solar panel.

[0082] In this embodiment, a solar power generation device and a thermoelectric power generation device can fully utilize the wearer's own energy and the energy in the environment. Combining the temperature difference between the wrist and the environment, as well as the collectable solar energy, a wristband integrating thermoelectric and solar power generation is constructed. This allows for the integration of power generation devices using multiple power generation methods, fully utilizing the energy forms available to the wrist-worn wearable terminal in various usage scenarios, achieving continuous and stable self-powering for the wrist-worn wearable terminal, and improving its battery life.

[0083] See also some possible implementations. Figure 6 As shown, the wristband is provided with a heat dissipation layer 10, a solar power generation panel 11 of the solar power generation device, a thermoelectric semiconductor component of the thermoelectric power generation device 13, and a heat conduction layer 14 from the outside to the inside. The back plate of the solar power generation panel is in direct contact with the cold end of the thermoelectric semiconductor component.

[0084] In this embodiment, the inner sides of the upper and lower straps are heat-conducting layers. The heat-conducting layers have good thermal conductivity and insulation properties. At the same time, the flexibility of the heat-conducting layers allows the wristband to better conform to the skin for heat conduction, which can reduce the contact thermal resistance between the hot end of the thermoelectric semiconductor and the wearer's skin, effectively establish a larger temperature gradient within a limited area, and improve the thermoelectric power generation efficiency.

[0085] In this embodiment, the heat dissipation layer 10 on the wristband can use a transparent, high-performance heat dissipation material, which enhances heat dissipation performance while ensuring that the solar power panel can capture more solar energy and convert it into electrical energy. It can also improve the efficiency of the solar power generation device by reducing the temperature of the solar power panel, and further reduce the cold end temperature of the thermoelectric semiconductor component of the thermoelectric power generation device, thereby improving the power generation efficiency of the thermoelectric power generation device.

[0086] Among them, see Figure 7 As shown, the positive electrode 1101 and the negative electrode 11 of the solar power panel 11 are both deployed on the back plate of the solar power panel 11. The direct contact between the back plate of the solar power panel 11 and the cold end of the thermoelectric semiconductor component can be understood as the back plate of the solar power panel being directly attached to the thermoelectric semiconductor component, thereby reducing the contact thermal resistance of the contact surface between the back plate of the solar power panel and the thermoelectric semiconductor component. The contact surface is the back plate of the solar power panel and the cold end of the thermoelectric semiconductor component.

[0087] The thermally conductive layer can have good thermal conductivity and insulation properties, and is highly flexible, so it can better fit the wearer's skin. This can reduce the contact thermal resistance between the hot end of the thermoelectric semiconductor component and the wearer's skin, effectively establish a larger temperature gradient within a limited area, and improve the power generation efficiency of the thermoelectric power generation device.

[0088] In this way, the capture of solar and thermal energy can be mutually beneficial. The solar panel uses flexible solar cells, and the thermoelectric generator is composed of rigid thermoelectric semiconductor grains and a flexible substrate. The two are bonded together to improve the efficiency of solar and thermal energy capture, while also enhancing wearability.

[0089] In some possible implementations, the plurality of said power generation devices include power generation devices, see [link to relevant documentation]. Figure 8 As shown and see further. Figure 4 As shown, the power generation device includes a magnetic rotor 17, a fixed shaft 18, and an electromagnetic coil 20. The power generation device converts mechanical energy into electrical energy, which is then used to drive an electromagnetic induction process through a specific mechanical structure (such as the relative motion between a magnetic rotor and a fixed shaft), thereby generating electrical energy to supply power to the load in the terminal. The power generation device can be configured within the dial of a wrist-worn wearable terminal, as described in the previous embodiment. In other words, the power generation device is integrated inside the dial; as the wearer's arm moves, it drives an eccentrically placed magnetic rotor to rotate, which in turn causes an electromagnetic coil to generate an electromotive force, thus supplying power to the load in the wrist-worn wearable terminal.

[0090] In a power generation device, the magnetic rotor is a rotating component made of magnetic material, whose magnetic pole configuration generates a changing magnetic field in the surrounding space as it rotates. A fixed shaft supports the rotating magnetic rotor and serves as a reference axis for its rotation. Wires can be wound around an iron core or a non-magnetic material to form a coil, thus creating an electromagnetic coil. When the electromagnetic coil is placed in a changing magnetic field, an electromotive force is generated, which in turn allows the output of current.

[0091] The magnetic rotor is magnetically connected to the fixed shaft, and the magnetic rotor can rotate eccentrically about the fixed shaft. In the eccentric rotation state, the electromagnetic coil can cut magnetic field lines to generate electromotive force.

[0092] In this embodiment, the edge of the magnetic rotor can attract and hold the fixed iron shaft. When the wearer's arm shakes or swings, it can drive the magnetic rotor to rotate eccentrically, so that the electromagnetic coil can cut the magnetic field lines to generate an electromotive force.

[0093] In this embodiment, the rotation center of the magnetic rotor does not coincide with its geometric center, thus forming an eccentric rotation with a fixed axis as the eccentric axis. This eccentric rotation allows the distance between the magnetic rotor and a fixed point to change periodically. When the magnetic rotor moves in a magnetic field, its direction of motion is not parallel to the direction of the magnetic field. The electromagnetic coil cuts the magnetic field lines, and according to Faraday's law of electromagnetic induction, an electromotive force is generated in the electromagnetic coil.

[0094] In this embodiment, the power generation device is based on Faraday's law of electromagnetic induction. A magnetic rotor is eccentrically connected to a fixed shaft. During rotation, the distance between the magnetic rotor and the fixed shaft periodically increases and decreases, causing the magnetic field around the rotor to continuously change with rotation. As the magnetic rotor rotates eccentrically, the magnetic field it generates changes relative to the fixed-position electromagnetic coil. This change in magnetic field causes the speed at which the electromagnetic coil cuts magnetic field lines to change, generating an electromotive force (EMF) in the coil. The magnitude of the EMF is proportional to the rate of change of the magnetic field; therefore, as the rotation speed of the magnetic rotor increases or decreases, the generated EMF changes accordingly. In other words, as the user walks or runs, their arm swings more intensely, allowing the power generation device to generate more electrical energy. This allows for comprehensive consideration of the wearer's arm swing amplitude and frequency during movement, and the wrist-worn wearable terminal is equipped with a mechanical energy harvesting dial. Thus, the wristband is equipped with a solar power generation device and a thermoelectric power generation device, while the dial is equipped with a power generation device, achieving the integration of multiple power generation devices. These multiple devices can work together to power the load, improving energy density. At the same time, it enables self-powered wrist-worn wearable terminals, solving the problem of insufficient energy supply due to limitations in application scenarios when relying on a single power generation method.

[0095] See also some possible implementations. Figure 8 As shown, the power generation device also includes a top cover 16, a coil fixing layer 19, and a bottom plate 21 that are constructed in a circular shape, wherein the geometric centers of the top cover 16, the coil fixing layer 19, and the bottom plate 21 coincide and have the same diameter. See Figure 9As shown, the fixed shaft 18 passes through the top cover 16, the coil fixing layer 19, and the base plate 21. The magnetic rotor is located in the rotor rotation space formed between the top cover and the coil fixing layer, and the electromagnetic coil is installed in the mounting hole on the coil fixing layer.

[0096] In this embodiment of the disclosure, the fixed iron shaft can pass through the center of the top cover to the center of the bottom plate, which can prevent the internal magnet from sliding irregularly.

[0097] In this embodiment of the present disclosure, the coil fixing layer can be a perforated disc, and the electromagnetic coils are embedded in the perforated disc of the coil fixing layer. There are 4 electromagnetic coils, which are symmetrically placed in the perforated disc of the coil fixing layer.

[0098] In some possible implementations, the top cover and the bottom plate are perforated disc structures, and the electromagnetic coil passes through the perforation in the bottom plate and is connected to the gating switch circuit.

[0099] In this embodiment, the base plate can also be a perforated disk. The diameter of the perforation in the base plate is smaller than the diameter of the electromagnetic coil, and the electrical energy generated by the electromagnetic coil is transmitted through the perforation in the base plate. The diameter of the magnetic rotor is larger than the diameter of the electromagnetic coil but smaller than the radius of the coil fixing layer. The electromagnetic coil is made of 600 turns of fine-diameter enameled wire. The outer ring 8 of the dial is made of a flexible metal material, which can enhance heat dissipation and improve the power generation effect of thermoelectric power generation. See also... Figure 4 , 8 As shown in Figure 9, there can be multiple electromagnetic coils 20, such as electromagnetic coil 1 (2001), electromagnetic coil 2002, electromagnetic coil 3 (2003), and electromagnetic coil 4 (2004). The four electromagnetic coils are symmetrically placed on the coil fixing layer 19. The coil fixing layer 19, top cover 16, and bottom plate 21 have the same geometric center and diameter, and are connected by a through-type fixing shaft 18 to prevent irregular sliding of the internal magnets, which would affect the power generation effect. Both the top cover 16 and the bottom plate 21 are designed as perforated disc structures, which protect the internal energy harvesting device while balancing the internal and external air pressure. Furthermore, the coils can transmit the captured and converted energy to the interface circuit through the perforations in the bottom plate 21.

For example, the watch face is a cylindrical structure with a diameter of 36 mm and a height of 5 mm, enclosed by a top cover 16 and a bottom plate 21. The four electromagnetic coils 2001-2004 have a diameter of 20 mm, a height of 3 mm, and a number of turns of 600.

The upper watch strap can include an outer side 101 and an inner side 102, and the lower watch strap can include an outer side 201 and an inner side 202. Multiple power generation devices can be deployed on the accessory.

[0103] In this context, collaborative power supply involves multiple power generation devices working together to meet the power demands of the load. Furthermore, powering the load in the terminal can be done directly, such as by supplying power to the display screen, or by having the power generation devices charge the battery in the terminal. The battery stores the electrical energy generated by the power generation devices and discharges it to the load when needed.

[0108] In some possible implementations, the outer array of the accessory is provided with a plurality of solar panels of the solar power generation device, the solar panels being connected in parallel via Schottky diodes.

[0109] In this embodiment, to improve the power generation efficiency of the solar power generation device, multiple solar panels of the solar power generation device can be rationally distributed according to the light intensity information of the wearing area. After each solar panel of the solar power generation device is connected to a diode, the positive and negative terminals are connected to form a parallel array. The solar panels transmit electrical energy to the energy fusion unit for output regulation through an interface circuit.

[0110] The solar panels can be made of materials that balance flexibility and conversion efficiency, such as perovskite solar cells. To prevent reverse current and minimize diode voltage drop, Schottky diodes are used to connect the solar panels of multiple solar power generation devices.
