Battery-free radio technology

The term batteryless radio technology describes the wireless transmission of signals of all kinds with the help of electromagnetic waves in the radio frequency range ( radio waves ) to a receiving module. The energy for sending the signal is obtained through energy harvesting , processed by means of energy-saving electronics and the data is finally transmitted in the form of short radio signals to a special receiving unit.

Batteryless radio technology is used primarily for RFID , radio switches and sensors in building automation ( Enocean ).
