Signal stabilization in a dielectric sensor assembly

摘要

A non-resistive contact sensor assembly includes an electric field sensor device, including a dielectric component for receiving an electrical signal from an object of interest and a signal processing component for processing the electrical signal, a voltage regulator for controlling voltage to the dielectric component and the signal processing component, and a common ground reference for the dielectric component and the signal processing component.

1. A non-resistive contact sensor assembly, comprising:
an electric field sensor device, including a dielectric component for receiving an electrical signal from an object of interest and an A/D converter for converting the electrical signal received from the object of interest to a digitized signal; circuitry interconnecting the dielectric component and the A/D converter and including a layer, directly below the dielectric component, that is substantially ground fill, the circuitry shielding the A/D converter from the dielectric component and serving as an internal partition providing an electrical field barrier against the dielectric component; and a fastening for fastening the non-resistive contact sensor assembly to an organism for measurement of characteristics of an organ of the organism.
