Powercast P2110 Harvests Ambient RF Energy from iPhone for Battery-Free Wireless Sensors

This video demonstrates the use of a standard iPhone in 2G mode to generate RF energy that is used to power a battery-free wireless sensor node. The sensor node is part of Powercast's Lifetime Power (TM) Energy Harvesting Development Kit for Wireless Senors (P2110-EVAL-01), the receiving board is based on the P2110 Powerharvester Receiver, and the antenna was slightly modified from it's original tuning for 915MHz.
