During the Sensors Expo 2011, Harry Ostaffe of Powercast demonstrated a credit card size prototype device for wirelessly charging thin-film batteries. The fully-integrated device included a 915MHz antenna, 915MHz Powerharvester with charging circuit, and thin-film batteries from CYMBET (EnerChip), IPS (THINERGY), and ST Microelectronics (EnFilm). The device was tested at the Powercast office to provide wireless charging at up to 50 feet.
