The described sensor has been used to measure small temperature changes in investigations related to the study of the properties of superfluid helium under zero-gravity conditions. The sensor requirements included high sensitivity, rapid response, small size, reproducibility, and ease of application to a test surface. In the preparation of the sensor a thin film of a commercially available carbon colloidal suspension is deposited on a substrate which must be electrically insulated or be covered with an insulating layer.
