COULD SENSOR NETWORKS RUN ON THIN AIR?

EnOcean "sensors are wireless, batteryless and maintenance free. Our groundbreaking components create energy seemingly from nothing, the slightest change in pressure, the smallest variation in temperature is enough to generate power for our ultra efficient sensors to make their readings and transmit their results.... [T]he harvesting of energy from the environment and...the use of radical power management techniques... enable our devices to run on minuscule amounts of energy. The net result is that EnOcean devices do not need batteries or an external power source, they can be deployed where they are needed, without the need to schedule retrieval for battery changing. By removing the need for maintenance we have revolutionised what is possible with wireless sensors."
