Ultraminiature Sensor for Thermal Analysis with an Air-Bridge Type Microheater

抄録

An ultraminiature sensor for thermal analysis is fabricated using micromachining technique and its fundamental characteristics are obtained. This device consists of monolithically integrated components of an air-bridge type microheater, a thin film thermocouple and a sample-holder. Boiling points of liquid samples, water and methanol, are clearly observed in the heating curve and the heating-rate curve, and sudden decrease of the temperature at the dropping time of the liquid sample without heating due to the effect of evaporation heat is also observed.
