Abstract: A force or pressure transducer (200) is disclosed. In one embodiment, the transducer (200) has a substrate (230), a dielectric material (220), disposed on the substrate (230), a spacing member (240), and a resilient element (210) disposed on the dielectric material (220) and the spacing member (240). A portion of the resilient element (210) is separated from the dielectric material (220), and a portion of the resilient element (210) is in contact with the dielectric material (220). The contact area between the resilient element (210) and the dielectric material (220) varies in response to movement of the resilient element (210). Changes in the contact area alter the capacitance of the transducer (200), which can be measured by circuit means.
