Non-toxic thermoelectric energy harvester could help enable the IoT
Energy scavenging electronics has long used the thermoelectric Seebeck effect to convert temperature differences into electric voltage. A Seebeck device creates voltage when there is a different temperature on each side. One bugaboo with using thermoelectrics, however, is that most employ toxic materials. But in a development that could help enable a variety of internet-of-things […]
