Nissha Printing Co., Ltd. has developed a prototype of the table type wireless charger with the use of the "capacitive coupling wireless recharging system" developed by Murata Manufacturing Company, Ltd.

As needs for smaller and thinner mobile devices and faster communication have grown, more and more people charge their smartphones and tablet PCs at their home and office. For this reason, expectations for the introduction of the wireless charge function that does not require the conventional power supply with necessary an AC adaptor has been rising.

We have succeeded to add the charge function to the prototype without impairing its appearance by installing a thin wireless charge electrode on the table surface. The prototype is designed in consideration of usage scenes in everyday life - the prototype can charge a smartphone and a tablet PC at the same time and has a built-in infrared ray sensor so that it turns on automatically when person approaches.
We are aiming to develop a wide range of wireless power transmission items such as the floor and the wall in addition to the table.

Wireless charge is enabled by placing a jacketed receiver with a thickness of 1.0 mm or less on the back surface of a smartphone or a tablet PC. The thickness of the electrode is 0.1 mm or less, so the wireless charge function can be provided with little change of the thickness of a mobile device and its charger.
The table top plate is oak and the wireless charge related icons are hidden, so the power transmission table is excellent in design as a piece of furniture.
