Abstract
A system for sensing movement comprising an elongate object having a restrained end and an unrestrained end which is free to move in at least two degrees of freedom in response to an applied force, the unrestrained end of the elongated object being configured to move in response to the applied force. An electrically conductive element is disposed on the elongate object and is configured to cooperate with the elongate object in producing a signal usable to determine the magnitude and direction of the movement of the unanchored end due to the applied force. Sensing circuitry is electrically coupled to the electrically conductive element and is configured for processing the signal from the electrically conductive element so as to determine a magnitude and a direction of deformation and produce a signal indicative of the magnitude and direction.
