Thermoharvester-driven wireless sensor node enables battery-free operation

摘要

Micropelt GmbH claims to offer the world's first commercially available thermo-powered wireless sensor system, the TE-Power NODE. The company's built-in chip thermogenerator takes a few degrees of temperature differential and harvests that thermal energy to operate the wireless sensor node, enabling unlimited battery-free operation. Wireless sensor networks offer many advantages. Market growth, however, lags behind expectations as many potential users avoid the burden of having to maintain hundreds or thousands of batteries.
