Potential of optical wireless power transmission

抄録

Optical wireless power transmission (OWPT) is a technology that uses highly directional light sources, such as lasers, and solar cells, to transmit power over long distances in a compact and efficient manner without wiring. It is expected to be used in various environments and applications, such as multiple Internet-of-things devices, mobility services, such as electric vehicles, drones and robots, and underwater and space applications, without generating electromagnetic noise. Owing to recent advances in light sources, power receiving elements, and related peripheral technologies, the practical application of this technology is progressing in some areas. This paper explains the basic principles and configurations, application examples, technical challenges, and future prospects of OWPT.
