Self-powered switch modules energises 2.4 GHz radio with kinetic energy

April 01, 2014 // By Graham Prophet
EnOcean has a battery-less wireless switch module that operates in the worldwide unlicensed 2.4 GHz band.

EnOcean claims the first energy harvesting wireless switch module, for consumer applications such as the control of LED lighting systems. It complements EnOcean’s established batteryless portfolio in the sub 1 GHz frequency band, used in building automation and smart home applications.

The 2.4 GHz switch module has the same form factor as EnOcean’s PTM 210 module in the sub 1 GHz frequency band, and fits in any standardised light switch. It is powered by EnOcean’s miniature world ECO 200 electromechanical energy generator. Converting kinetic energy into electrical energy it works in the same way as a small dynamo, drawing out and delivering this power to a wireless module.
