摘要： An electric field sensor employs a capacitive pick-up electrode in a voltage divider network connected to a body emanating an electric field. The system is relatively insensitive to variations in the separation gap between electrode and body, reducing sensor motion artifacts in the output signal and stabilizing its low frequency response. The pick-up electrode may be positioned at a “stand off” location, spaced from intimate contact with the surface of the body. This is equivalent to providing low level capacitive values for the capacitive coupling between the pick-up electrode and the body whose electric field is to be monitored. Or a series limiting capacitor may be provided in the input stage. Human body-generated electrical signals may be acquired without use of conductive gels and suction-based electrodes, without direct electrical contact to the body, and even through thin layers of clothing.

摘要： A bio-electrode for conveying electrical signals to, or from a body is constructed with two components, a pre-laminated member and a re-usable electrode assembly. The pre-laminated member comprises a first substrate layer and a second electrolyte-containing layer. The substrate contacts the body and is constructed of a material that is biocompatible, hydrophilic and inherently electrically semi-conductive or conductive. The electrolyte-containing layer, which does not contact the body, is composed of an adhesive, electrolytic hydrogel. Small amounts of moisture and electrolytes from the hydrogel diffuse into the substrate thereby reducing and stabilizing the substrate's electrical resistance. The pre-laminated member can be used with existing re-usable electrode assemblies.
