| 概要 |
Wireless power transfer (WPT) technology is expected for eliminating troublesomeness of connecting an electronic cable. The development of WPT technology has a long history since Nikola Tesla built up... Wardenclyffe Tower located in Long Island, New York for developing a WPT system in the early 1980’s. But it cannot be said that WPT technology is widely spread in a current human life space enough. The reason is that it cannot find the specific application which only WPT can achieve yet. There are two types of WPT for short-range power transmission. One is the inductive coupling power transfer (IPT), and the other is the capacitive coupling power transfer (CPT). We have been working on the development of CPT technology although it is a minor one comparing with IPT because it has unique features such as wide transfer area, simple structure, and so on. In this presentation, three CPT applications we have developed are presented. The first application is to an e-Paper, a reflective display showing a paper white appearance. We could eliminate the battery from the device, which enables the real paper-like shape. The second application is for an organic light-emitting diode (OLED) lighting, a new lighting using OLED. The lighting panel consists of only OLEDs with flexible plastic substrate and rectifying diodes, which results in a very simple and ultrathin lighting device. The last is for a drone or a small multicopter. By using CPT system, a wide charging area for the drone to land especially required at autonomous flying was provided.続きを見る
