Abstract
A planar sensor for sensing lateral displacement and shear measures the displacement of a small ferromagnetic or diamagnetic target that is positioned and allowed to move laterally over a series of specially shaped and orientated planar coils. The coils are preferably multi-layer printed circuit boards (PCB) that contain the planar windings and in other embodiments can be fabricated using flexible PCBs or using micro electromechanical (MEMS) assemblies. The target displacement is constrained to a general area and in multiple lateral directions (measuring shear).
