RF Energy Harvesting
Digging a bit deeper in the topic we found some insights on the RF Energy Harvesting technology from Powercast that won a Gold-level “Best of Sensors Expo” Award at the 2009 Sensors Expo, also in the previous post. A compilation of awards is available in this article of Sensor Magazine.
At the Darnell nanoPower Forum on May 18th, Powercast and CAP-XX presented this battery-free wireless power module (left) for wireless sensors. The module uses the Powercast P2100 Powerharvester receiver, a CAP-XX supercapacitor, and the TI eZ430-RF2500 wireless board and thus harvest RF from the environment to power the TI module running SimpliciTI.
