Issues and Initiatives for Practical Deployment of Wireless Power Transfer Technologies in Japan

The Broadband Wireless Forum (BWF) was established in Japan under the guidance of the Ministry of Internal Affairs and Communications, Japan, to enhance future wireless technologies through collaboration involving industry, government, and academia. Wireless power transfer (WPT) is one of the key technologies expected to lead to the emergence of new business fields in the near future. In this context, the Wireless Power Transmission Working Group (WPT-WG) was formed in BWF to discuss problems concerning the commercialization of WPT technologies. In this paper, issues and initiatives of WPT-WG are presented.
