Abstract

A temperature-change sensor by thermoelectric elements that is directly connected to a p-type element and an n-type element was developed. A β-FeSi2 thermo-electric semiconductor made by a spark plasma sintering method was used as a prototype sensor. Evaluation of this thermoelectric temperature-change sensor was carried out by measuring its electromotive force when it was dropped into a thermo-stated water bath. It was confirmed that there existed a correlation between the temperature difference and the electromotive force of the sensor, i.e., approximately 5 mV of electromotive force was generated at a temperature difference of 30 K. In addition, the dependence of electromotive force on the size and properties of the thermoelectric elements was evaluated by carrying out FEM analysis.
