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 the shear-stress sensor. A silicon-micromachined, floating-element shear-stress sensor has been dynamically calibrated up to 4 kHz using this method. These data represent the first broadband, experimental verification of the dynamic response of a shear-stress sensor.
