The article reports on the development of a thermomechanical sensor by the researches at Arizona State University in Tempe based on polymer wire stretched across a microfabricated quartz tuning fork. The output frequency of the fork was determined by measuring the change in output amplitude as the resonant frequency shifted from the driving frequency. Furthermore, the group is also investigating polymer wires with better thermoresponsive properties.
