Extraction of temperature dependent parameters for an electrothermal model of thermoelectric energy harvester

A method and procedures have been developed for extraction of temperature dependent parameters of a thermoelectric energy harvester. Temperature functions of Seebeck coefficient S, electrical resistance R, and thermal conductance K were carried out. They are all indispensable for accurate simulation of complex electro-thermal processes associated with conversion of small pieces of free heat energy. The paper discusses the modelling of a single tiny thermoelectric generator with high-density pellets placement. It is intended to be used as a single building block in a wearable thermoelectric matrix for harvesting and conversion of human warmth to electricity.
