Recently unveiled by Lord Drayson, the Freevolt device harvests ambient energy from RF radiation to power small devices.
The smartphone-sized Freevolt harvests the RF energy from broadcast, WiFi and cellular networks using a multi-band antenna and an “ultra-efficient rectifier” paired with a sophisticated power management system. The antenna can capture the energy from a number of different frequencies, allowing the Freevolt to power small devices like smoke alarms, wearables and building sensors.
According to Drayson, the technology could also be scaled up, with the potential of powering more power-hungry devices.
