Abstract
A system for the evaluation of temperature changes in living tissue at a dimensional level of a single cell is described. A glass micropipet te the tip of which is filled with semiconducting glass (Rech et al. 1 992), is used as a microsensor. The changes of conductivity of the sen sor due to variations of temperature are evaluated by electronic circu itry based on the measurement of an AC current of sinusoidal waveform flowing through the sensor. Temperature changes in range of 0.01 K can be detected in this way.
