Waste-Heat thermoelectric power source for industrial wireless transmitters

This paper presents Seebeck effect-based thermoelectric power source utilizing waste heat in manufacturing processes for industrial wireless transmitters. An industrial wireless transmitter can be supplied by its internal battery in combination with the proposed thermoelectric power source to conserve battery lifetime. Moreover, the proposed power source can operate as the backup power supply for new battery replacement without tuning the transmitter off. Experimental results showing the capacity to power a Rosemount 3051S wireless pressure transmitter as a target application example are also included.
