Abstract
A pressure sensor is disclosed which includes a transmit electrode adapted to be operatively connected to a signal generator, a receive electrode adapted to be operatively connected to a signal receiver and signal processor, and a variably resistive conductive deformable element. The transmit electrode, the receive electrode and the variably resistive conductive deformable element being positioned in proximity to each other such that a pressure event proximate to the variably resistive conductive deformable element causes a change in coupling between the transmit electrode and the receive electrode, and a signal transmit on the transmit electrode as received on the receive electrode is changed in at least one of magnitude or phase in relation to and as a result of a pressure event.
