Abstract :
For several years, research has been underway on the use of electron tunneling as a displacement transducer in microsensors. This report describes recent measurements of low frequency noise and temperature coefficient of sensitivity tunneling transducers. Since the dominant source frequency noise in these transducers is due to thermal expansion mismatch, small modifications to the device structure should significantly improve the tunneling transducer performance
