Abstract
Solid-state stress sensors are presented herein. A sensor system may include a substrate, a first layer of sensing material disposed on a first surface of the substrate and at least two electrodes forming an electrode pair. The at least two electrodes may include a first electrode and a second electrode. The first and second electrodes may be offset from each other in a direction substantially parallel to the first surface. The sensing material may be a piezoelectric material and the sensor system may be configured to generate an output signal in response to shear stress experienced by the sensing material.
