Add Hidden Wireless Charging to Any Desk or Surface!
A student at the University of Tokyo has developed a system for wireless charging of electronic devices in the form of a flexible sheet that can be formed into any shape or even cut with scissors to fit the shape of specific surfaces and objects..
The presented prototype is capable of remotely transmitting energy to gadgets. Currently a square sheet with a side of 400 mm can generate 2 to 5 watts. This power is enough to charge a smartphone or smart watch. The invention is not only thinner than other wireless charging devices, but also has a large usable area..
Unique properties are due to by a special method of electrical wiring, thanks to which the sheet can be easily cut to the required dimensions, since the charge is generated by special coils located on its surface. With a sufficient number of them, the device will continue to function stably.
The system is quite thin and has high levels of flexibility, which allows it to be folded and bent without damage. Therefore, the sheet can be placed on any surface, and even inside a bag or jacket..
Ryo Takahashi, the student behind the invention, plans to improve the wireless system to enough power to charge a small laptop and make it more «invisible». He expects that in a few years his invention will be incorporated into furniture, toys and clothing..
Researchers from Osaka University have presented an equally interesting version of a flexible material for powering electronic devices. Their invention converts heat into electricity..
