Abstract

Presented in this paper is the development of a novel class of heat energy harvesting systems that are designed to generate electrical energy from sources with highly varying temperatures that can be significantly higher than thermoelectric generators (TEG) can withstand. This class of TEG-based heat energy harvesters are designed to: (a) apply a constant temperature gradient to TEGs of the system while heat source temperature is varying and can be significantly higher than TEGs can withstand (thus, the total energy output is maximized); and (b) provides a passively operated switching mechanism for the protection of TEGs from overheating.
