Abstract
In accordance with one embodiment, a sensor includes a fibrous region contacting at least two electrodes. The fibrous region has an electrically conductive coating. The fibrous region has a resistance and when the fibrous region is compressed, the resistance changes. In another embodiment, a method of making a pressure responsive sensor includes providing a compressible material, applying a conductive coating to the compressible material to provide a coated compressible material having a resistance, and placing the coated compressible material in contact with at least two electrodes, wherein when the compressible material is compressed, the resistance changes.
