In this article, a new sensor is presented that measures the shear stress based on the phase difference. In this method, first, using a spring, the force resulting from the shear stress is converted into displacement, and then the displacement is measured. The basis of displacement measurement is the induction of current between two flat coils that are opposite each other. One of these coils is fixed and the other is movable. Each step that the moving coil moves on the fixed coil, its output voltage changes its phase by 2ℼ. Because the resulting phase difference is proportional to the displacement, the amount of movement of the moving coil can be obtained from the measurement of the phase difference. Based on this, a two-dimensional sensor has been designed and simulated that can measure in both x and y directions. The simulation has been done mechanically-magnetically, that is, for moving the electrodes, the output phase difference has been obtained separately in both x and y directions.
