Microfabrication techniques that allow the integration of all the components in compact and effective volumes, along with the developments observed in sensor and actuator miniaturization, optimization of microelectronic circuits and, ultimately, wireless communication capabilities, have provided the tools required to develop implants for applications so far technically impossible. However, the scaling down of implantable devices raises the problem of how to power them, since batteries have not scaled down as much as the implants. Consequently, energy sources for implantable electronic devices that do not rely on, or at least mitigate, the requirement for a battery are emerging at an astonishing pace. This paper presents a comprehensive review of recent implantable bioelectronic devices that employ alternative powering methods such as energy harvesting and wireless power transfer. A comparison between the different powering methods is provided, along with a discussion of how these may be suited for the device of the future.
微制造技术能够将所有组件集成在紧凑且高效的体积中，同时伴随着传感器和执行器小型化、微电子电路优化以及最终无线通信能力方面的进展，这些都为开发迄今技术上无法实现的应用植入物提供了所需工具。然而，可植入设备的小型化引发了如何为其供电的问题，因为电池的小型化程度不如植入物。因此，不依赖电池或至少减轻对电池需求的可植入电子设备能源正以惊人的速度涌现。本文全面综述了近期采用能量收集和无线电力传输等替代供电方法的可植入生物电子设备。文中对不同供电方法进行了比较，并讨论了它们如何适用于未来的设备。
