Abstract
The design and implementation of a novel dynamic calibration technique for shear-stress sensors is presented. This technique uses the oscillating wall shear stress generated by a traveling acoustic wave as a known input to th e shear-stress sensor. A silicon-micromachined, floating-element shear-stre ss sensor has been dynamically calibrated up to 4 kHz using this method. Th ese data represent the first broadband, experimental verification of the dy namic response of a shear-stress sensor.
