Drayson Technologies has used CST electromagnetic simulation software to help develop Freevolt, a revolutionary energy harvesting technology that turns unused RF signals into electricity. Freevolt, which was launched by Drayson Technologies in September 2015, is the first viable power source of its kind.
Harnessing these unused fields requires very efficient devices that can operate in a range of conditions. Drayson Technologies used CST STUDIO SUITE to simulate and develop the antenna designs and wireless power transfer technology used in Freevolt and to develop coil designs for induction-power transfer (IPT). The wide selection of solvers in CST STUDIO SUITE made it possible to model these different components within a single interface.
The compact and lightweight Freevolt harvester absorbs energy from multiple RF signals, including Wi-Fi, 2G, 3G, 4G and digital broadcasts, to power low energy devices such as sensors, beacons, security tags or wearables. The first commercial application of Freevolt is the CleanSpace Tag, a personal air quality sensor created by Drayson Technologies.
About Freevolt
Freevolt is a new technology set to revolutionise the way the future is powered. It harvests ambient radio frequency (RF) energy from broadcast, mobile and WiFi networks – energy that is currently unused – to produce small amounts of electricity. Freevolt enables a range of Low Energy Internet of Things (LE-IoT) devices to be Perpetually Powered negating the need to change batteries or to plug-in to charge. The Drayson Technologies CleanSpace Tag is the first commercial application of this technology. Freevolt is available through license to the international developer community.
