A Simple and Direct Method for Local Temperature Measurement and its Applications to Materials Evaluations
General thermometers pose difficulty in measuring the actual surface temperature of a micro-area, especially in electronic devices. In the present study, an approach to direct measurement of surface temperature is described, which utilizes the potential of melting point of different chemical reagents. The present technique exhibits a temperature resolution of about 5○C and the measurable maximum temperature of about 200○C. A short comment on the application of the technique to determine the actual surface temperature of small areas in some engineering applications is also stated.
