The use of transistor for measurement of body temperature.
The use of transistor for measurement of body temperature. Acta physiol. pol., 1981, 32 (6); 761-764. A plastic chip silicon transistor was used for measurements of skin surface, auditory canal and rectal temperatures in human subjects. The application of a transistor as a temperature sensor was based on a linear relationship between base-emitter voltage and temperature changes. A slightly modified digital multimeter was used to supply the transistor and to obtain temperature readout. Construction of the sensors, electronic circuit and calibration procedure are presented in detail.
