A local thermometry technique based on proximity-coupled superconductor/normal-metal/superconductor devices is discussed. A thermometer is developed which dramatically enhances the ability to measure the local electron temperature Te at low temperatures. The technique is helpful in measuring small temperature gradients across a micron-size sample, hence opening up the possibility of quantitatively measuring the thermal properties of mesoscopic devices.
