Install and Forget: Batteryless Radio Sensors

Siemens has developed a variety of energy autarkic radio sensors that draw the energy they require for operation from their surroundings. The technology can be used to automatically monitor facilities in remote areas, for example. These sensors require no wiring and once installed work completely maintenance-free for many years. They essentially draw their energy from the environment - in the form of light or vibrations - and transmit their measured data by radio.
