1. An apparatus comprising:

  • an interface layer configured and arranged to flex in response to an input signal presented to the interface in the form of pressure;

    a dielectric structure including an elastomeric material that is configured and arranged to exhibit a first dielectric constant and, in response to the pressure, to compress and thereby exhibit a changed dielectric constant corresponding to a state of compression of the elastomeric material; and

    a sense circuit configured and arranged to respond to the change in dielectric constant by providing an indication of the pressure applied to the dielectric.
