Abstract

A non-resistive contact sensor assembly includes an electric field sensor device, including a dry electrode component for receiving an electrical signal from an object of interest and a signal processing component for processing the electrical signal, and a casing in which the signal processing component is surrounded or embedded. The processing component may include communications capabilities.
