title: Force measurement using an inductively coupled sensor.
abstract: A low-compliance, high-bandwidth force sensor is described. The bending of a quartz plate is converted to an analog voltage by using a phase-locked loop to measure the change in frequency of two oscillators inductively coupled to the plate. The resolution of the sensor is approximately 10(-5) N, with a bandwidth of approximately 1 kHz.
