Joint Production of Prototype Wireless Recharging Housing for Mobile Devices

September 15, 2011

Nissha Printing Co.,Ltd.

Murata Manufacturing Co., Ltd. (Murata Manufacturing) and Nissha Printing Co., Ltd. (Nissha Printing) have jointly produced a prototype housing for conveniently and wirelessly recharging mobile devices.
The housing has a power receiving circuit for electric field coupling wireless recharging (developed by Murata Manufacturing), while a decoration film (electrode) with antenna function (developed by Nissha Printing) is integrated into a smartphone battery cover.
The antenna film is thin and flexible and can be made transparent, making it possible to add a wireless recharging function to smartphones and other mobile devices without altering their appearance. Additionally, using Nissha Printing’s in-mold decorating technology to attach an electrode to the housing, it is possible to increase power transmission efficiency.
The prototype will be displayed and demonstrated at CEATEC JAPAN 2011.
