A system is designed to extract energy from background RF energy in the ambient due to radio and wireless communication sources. This energy is harvested on a continuous basis and stored on-board to provide power for anti tamper systems. This eliminates the need for maintenance of battery sources that would otherwise be needed to power the device electronics. With a maintenance free power source provided by harvesting energy from the environment the sensors can operate for an unlimited time unattended.
Benefit: Powering electronics from ambient RF backgrounds eliminates battery maintenance in wireless devices. Potential commercial application is wireless recharge of batteries in portable electronic devices and sensor networks.
