Abstract

Fine thermoelectric elements were fabricated on an electrode chip where the tips of the Pt and W thin wires having the diameter of 5 μm were welded together by Joule heat welding. Firstly, the dissimilar metal weld was contacted to thin wire heater and the voltage appeared in the circuit due to Seebeck effect was measured. Current was supplied to the one of the thermoelectric element and the temperature at the Pt/W weld was measured by the other element. It was found that the temperature at dissimilar metal weld depended on the direction of current and Peltier effect was successfully observed.
