Abstract
A wireless energy extracting device includes: a radio frequency (RF) generator module for wirelessly receiving an RF charging signal to generate electrical energy; a capacitor module; and an energy management module coupled to the RF generator module and the capacitor module, and used to be coupled further to an energy consuming device. The energy management module performs electrical energy transfer from at least the RF generator module to at least the energy consuming device. Therefore, the wireless energy extracting device has relatively low electrical energy loss and thus relatively high energy usage efficiency.
