Abstract
A multi-dimensional position sensor includes at least three curved triangular-shaped sense inductors and a movable shaft that incorporates a conductive material. The distance of the movable shaft from the sense inductors varies as the shaft is moved in a two-dimensional plane. The variation in distance causes a variation in the inductance of each of the triangular-shaped inductors and this variation in inductance may be used to determine the physical position of the movable shaft through means of triangulation calculations.
