Abstract

Some aspects are directed to a system for wirelessly powering a pair of three-dimension (3D) glasses, and to a wirelessly powered 3D glasses. The system uses a powering device for generating and transmitting a wireless power signal, and a rectenna integrated within the 3D glasses for receiving the wireless power signal. The rectenna converts the wireless power signal into a Direct Current for powering the 3D glasses. The 3D glasses comprises a frame, a pair of Liquid Crystal Shutters supported by the frame, and a rectenna for receiving a wireless power signal and transforming the wireless power signal into a direct current signal for powering the 3D glasses.
