Wireless Charging Solutions

Renesas Electronics Corporation

This video demonstrates wireless electric transmission and receiving with no physical contact. The receiving device controls all its functions in one microprocessor chip, allowing it to be miniaturized. The transmitting device can use batteries for mobile devices, which allows it to be used as a convenient mobile power transmission device. Because system-wide efficiency is at 85% at ultra low loads (1mA), it can potentially be used as a long-life mobile battery.
In the video, the system powers a small wearable device and a healthcare device.
