  abstract = {A microcomputer based instrument to measure thermal conductivity, thermal diffusivity and perfusion at the surface of a tissue has been developed. Self-heated spherical thermistors, partially embedded in an insulator, are used to simultaneously deliver thermal energy to the biological tissue and to measure the resulting temperature rise. The temperature increase of the thermistor for a given applied power is a function of the combined thermal properties of the insulator, the thermistor and the tissue. Once the probe is calibrated, the instrument accurately measures the thermal properties of tissue. Conductivity measurements are accurate to better than 2\% and diffusivity measurements are accurate to better than 4\%. The surface thermistor probe is quite sensitive to perfusion.},
