Markets For Thermoelectric Generators
Wireless sensors powered by thermoelectric generators in environments where temperature differentials exist would lead to avoiding issues with battery lifetime and reliability and lead to an increase in wireless sensor network implementations. It would also lead to the ability to move away from wired sensors, which are still the solution of choice when increased reliability of measurement over prolonged periods of time is necessary. Some applications have low enough power demands to operate with small temperature differentials, as small as a few degrees in some cases. Some other segments on the other hand are characterized by extreme temperature differentials but at the same time, have very stringent safety requirements which could lead to long development times -e.g. condition monitoring of turbine blades while in-service. These varying kinds of considerations pertaining to different segments demonstrate the versatility that needs to be demonstrated by the technology developers in order to capture available opportunities in different verticals.All news
