Dynamic Calibration of a Shear-Stress Sensor Using Stokes Layer Excitation – AIAA Jan 1998

The design and implementation of a novel dynamic calibration technique for shearstress sensors is presented. This technique utilizes 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. This data represents the first broad-band, experimental verification of the dynamic response of a shear-stress sensor.
