Wearable technology is emerging as a solution for various bio-mechanic and health-metric applications. Solar photovoltaic energy is a viable supplemental power source that can reduce battery size requirements in wearables. This study outlines the considerations for a wearable sleeve device and its associated power converter system using commercially-available flexible photovoltaic panels located on the forearm. Investigation of the effects of curvature shows that while curvature of the panel around a forearm does reduce output power, the angle relative to the light source has a more pronounced effect on both output power and voltage characteristics. Among various panel arrangements on the forearm, that with five individual panels of smaller width provided the highest output power after the boost converter power stage. Testing under various static positions, the PV sleeve provided up to 94 mW outdoors, which can effectively reduce the battery size while maintaining user safety.
可穿戴技术作为各种生物力学和健康计量应用的解决方案正在兴起。太阳能光伏能源是一种可行的补充电源，可以减少可穿戴设备对电池尺寸的要求。本研究概述了使用位于前臂的商用柔性光伏电池板的可穿戴袖套设备及其相关的功率转换系统的注意事项。对曲率影响的研究表明，虽然面板围绕前臂的曲率确实会降低输出功率，但相对于光源的角度对输出功率和电压特性的影响更为显著。在前臂上的各种面板布置中，经过升压转换器功率级后，具有五个较小宽度的单独面板的那个提供了最高的输出功率。在各种静态位置下进行测试时，PV 袖套在户外可提供高达 94mW 的功率，这可以在保持用户安全的同时有效减小电池尺寸。
