For internet-of-things (IoT) terminals, which consist of many sensors and beacons, wiring and using battery are ineffective power supply methods due to excessive installation and maintenance work cost. Nowadays, existing wireless power transmission technologies are still immature. In this paper, LED-array optical wireless power transmission (OWPT) systems which have a portable size and can supply electricity power of nearly 400 mW remotely at 1 m for compact IoT terminals are designed and demonstrated.
