Radio wave energy-harvesting technology is moving forward. It can now be used in a number of applications such as cell phone-charging and supporting wireless technology by doing away with battery recharge. The technology is moving in the direction of harvesting ambient radio wave energy but so far it is responsive to specific targeted frequencies.Product Design and Development reports:
"Powercast’s P2100 Powerharvester™ module is one of several components from the company that convert radio frequency energy into direct current. The Powerharvester won a Gold award in the sensor components category at Sensors Expo 2009. See article.
