Abstract
A system and method for self-harvesting energy from a wireless device and supplementing the battery power of the wireless device using the self-harvested energy includes the steps of collecting at least a portion of radio frequency signals transmitted by the wireless device; converting the collected radio frequency signals from radio frequency signals to direct current energy; further converting the direct current energy to energy compatible with charging requirements for a battery electrically connected to the wireless device; and transferring the compatible energy to the battery of the wireless device through a wireless device interface in order to add the compatible energy to the battery.
