1. A non-resistive contact sensor assembly, comprising:
- (a) an electric field sensor device, including a dry electrode component for receiving an electrical signal from an object of interest by capacitively coupling with the entity;
(b) a cover in which the electric field sensor device is surrounded or embedded;
(c) a conductive casing which is part of the cover;
(d) a biasing structure, disposed on the outside of the cover, that is adapted to press the conductive casing against a surface of the object interest when biased by a belt;
(e) wherein the conductive casing is electrically isolated from the dry electrode component; and
(f) wherein the conductive casing is electrically grounded via a ground connection to a power cable of the assembly.

Abstract
A non-resistive contact sensor assembly includes an electric field sensor device, a cover, and a biasing structure. The electric field sensor devices has a dry electrode component for receiving an electrical signal from an object of interest by capacitively coupling with the entity. The signal processing component is surrounded or embedded in the cover. The biasing structure is disposed on the outside of the cover and is adapted to press the dry electrode component against a surface of the object interest when biased by an external structure.
