Use of Piezoresistive Materials in the Measurement of Displacement, Force, and Torque
W. P. Mason, R. N. Thurston · The Journal of the Acoustical Society of America · 1957
The use of piezoresistive materials as strain gauges and in the measurement of displacement, force, and torque is discussed generally. A torsional transducer which has been constructed from n-type germanium is described, and the experimentally obtained voltage-torque characteristic given.
