Abstract: A means for determining the electrical resistance and resistivity of thermoelectric material allows quality control at all steps in the construction of a bismuth telluride and antimony telluride thermoelectric generator. The method involves measuring negative thermoelectric voltage with no current flowing and then a measure of negative thermoelectric voltage while forcing known current through the material in the same direction as shorted to accurately determine thermoelectric resistance. A manual and automatic method of manufacturing thermoelectric rings using forcing current for in-process testing means.
