Recent advances in soft materials and mechanics activate development of many new types of electrical medical implants. Electronic implants that provide exceptional functions, however, usually require more electrical power, resulting in shorter period of usages although many approaches have been suggested to harvest electrical power in human bodies by resolving the issues related to power density, biocompatibility, tissue damage, and others. Here, we report an active photonic power transfer approach at the level of a full system to secure sustainable electrical power in human bodies. The active photonic power transfer system consists of a pair of the skin-attachable photon source patch and the photovoltaic device array integrated in a flexible medical implant. The skin-attachable patch actively emits photons that can penetrate through live tissues to be captured by the photovoltaic devices in a medical implant. The wireless power transfer system is very simple, e.g., active power transfer in direct current (DC) to DC without extra circuits, and can be used for implantable medical electronics regardless of weather, covering by clothes, in indoor or outdoor at day and night. We demonstrate feasibility of the approach by presenting thermal and mechanical compatibility with soft live tissues while generating enough electrical power in live bodies through in vivo animal experiments. We expect that the results enable long-term use of currently available implants in addition to accelerating emerging types of electrical implants that require higher power to provide diverse convenient diagnostic and therapeutic functions in human bodies.

软材料和力学的最新进展推动了许多新型电子医疗植入物的发展。然而，提供卓越功能的电子植入物通常需要更多的电能，从而缩短了使用时间，尽管已经提出了许多方法来解决与功率密度，生物相容性，组织损伤等相关的问题，从而在人体中获取电能。 。在这里，我们报告了一种在整个系统级别上有效的光子功率传输方法，以确保人体可持续的电能。有源光子功率传输系统由一对可贴在皮肤上的光子源贴片和集成在柔性医疗植入物中的光伏器件阵列组成。可贴在皮肤上的贴片主动发射光子，该光子可以穿透活体组织，从而被医疗植入物中的光伏设备捕获。无线功率传输系统非常简单，例如，无需额外电路即可从直流电（DC）到DC的有功功率传输，并且无论天气如何，白天是否被衣服覆盖，室内或室外均可用于植入式医疗电子设备。通过展示与软活组织的热和机械兼容性，同时通过活体在活体内产生足够的电能，我们证明了该方法的可行性 不论白天或黑夜，无论天气如何，都可以用于植入式医疗电子设备，无论是室内还是室外，都可以被衣服覆盖。通过展示与软活组织的热和机械兼容性，同时通过活体在活体内产生足够的电能，我们证明了该方法的可行性 不论白天或黑夜，无论天气如何，都可以用于植入式医疗电子设备，无论是室内还是室外，都可以被衣服覆盖。通过展示与软活组织的热和机械兼容性，同时通过活体在活体内产生足够的电能，我们证明了该方法的可行性体内动物实验。我们希望，除了加速需要更高功率才能在人体中提供各种便捷诊断和治疗功能的新兴电子植入物之外，这些结果还可以长期使用当前可用的植入物。
