Abstract

Sensors, sensing arrangements and devices, and related methods are provided. In accordance with an example embodiment, an impedance-based sensor includes a flexible dielectric material and generates an output based on pressure applied to the dielectric material and a resulting compression thereof. In certain embodiments, the dielectric material includes a plurality of regions separated by gaps and configured to elastically deform and recover in response to applied pressure.
