Abstract

In recent years, various types of small electronic devices have become widespread. Optical wireless power-transmission (OWPT) systems can be charged over long distances and are promising candidates for systems that do not require dry batteries. In this study, we propose a wireless power-transmission method for supplying power to small electronic devices and demonstrate wireless power transmission. A crystalline Si (c-Si) solar cell and power-storage device incorporated into small electronic devices enable optical wireless power transmission systems using near-infrared LED lights and can be used to eliminate dry batteries.
