We calculated the stability criterion for the modified power law model and subsequently adjust the model such that it's stability can be guaranteed. We applied both a sinusoid, a chirp, an exponentially decaying sine and bandwidth limited noise position excitation to a 3D printed symmetric piezoresistive cantilever and measure the differential response. A modified power law model is fitted directly to the inverse of the sensor data, to directly obtain a compensator for the sensor. The result
