Freevolt Turns RF Waves in to Usable Electricity to Charge IOT Devices

Freevolt : Perpetual Power

Drayson Technologies has introduced a revolutionary energy harvesting technology called Freevolt that turns ambient radio frequency waves into usable electricity that can charge Low Energy Internet of Things (LE-IoT) devices. The patented technology was developed by an international team from Drayson Technologies and Imperial College London. Drayson Technologies is the first to market with this technology, which is now commercially available for license to the developers and the business community.

Companies have been researching how to harvest energy from WiFi, cellular and broadcast networks for many years. But it is difficult, because there is only a small amount of energy to harvest and achieving the right level of rectifying efficiency has been an issue. Drayson Technologies has solved this problem of harvesting usable energy from a small RF signal. The Freevolt harvester comprises a multi-band antenna and rectifier, which is capable of absorbing energy from multiple RF bands at almost any orientation. Its a patented, pioneering technology that harvests radio frequency (RF) energy from wireless and broadcast networks such as 2G, 3G, 4G, WiFi & Digital TV.

The small, lightweight design is scalable and suitable for a range of uses, from the ever expanding low-power Internet of Things, such as wearables, sensors and beacons, to built environments, with the potential to integrate Freevolt into the fabric of urban and industrial architecture. This technology creates a crowd-sourced network of personal air sensors, initially across the UK and then expanding to major cities across the world, which will all be powered by Freevolt.

Dryson Technologies has worked with the PA Consulting Group, Radius Networks and Foster & Partners to bring this technology to life.

The first commercial application of Freevolt technology is the CleanSpace Tag air sensor, which is currently being manufactured in the UK and is available for purchase as of today.
