Abstract
Across the domain of Internet-of-Things sensors, a key factor which restricts the long-term operation of devices is energy. This restriction becomes especially prominent as the size of devices is decreased and flexibility is needed, for example in body-worn applications. This publication documents the design, optimisation, fabrication and verification of a novel flexible thermoelectric energy harvesting system for powering body-worn sensors. A solution is produced which is able to transmit temperature information at 25 minute intervals by harvesting 13.6 μW of energy from a 25K temperature difference.
