Abstract
As a temperature measurement apparatus using a surface acoustic wave of a piezoelectric substrate that performs temperature measurement wirelessly and without power supply, the temperature measurement apparatus accurately measures the temperature of the thermocouple tip end by analyzing the frequency characteristics of the surface acoustic wave propagating on the piezoelectric substrate and including temperature information of the piezoelectric substrate, and detecting change in propagation time of the surface acoustic wave of the piezoelectric substrate that is changed by the electromotive force of the thermocouple.
