Abstract:
A sensor (10) is capable of detecting linear acceleration in the three Cartesian directions and the angular acceleration about three Cartesian axes. The sensor (10) has a conductive layer (32) that is free to move or rotate in any direction. A first, second, and third set of conductors are used to sense and quantify the acceleration of the conductive layer (32). The sensor (10) can also be operated as a closed loop system with the addition of a fourth set of conductors.
