Experimental studies of the characteristics of the commercial thermoelectric sensor for heat energy harvesting

This paper studies the characteristics of TEC1-12706 thermal sensor for harvesting heat energy with single element, two serial elements, and two paralel elements. The experiments were designed by building the well-controlled system to make sure the generated data is valid. The observed characteristics include oven circuit voltage, constant load current and temperature variations. The studies produce the voltage and current patterns to temperature variations. The evaluated sensor is able to harvest the heat and transform it to useful voltages.
