Abstract
Methods and systems for detection of an electric field generated by the human/animal body can include providing a passive antenna system for detecting changes in the ambient electric field due to interaction of the ambient with the charges generated by the human/animal body, and a high impedance sensor that is fixed to the encapsulated wire antenna. The result is a passive human/animal detection system without any moving parts. The antenna can be an encapsulated wire, and the wire length can be chosen according the desired application. For systems that are intended to detect the presence of a human being or animal, the encapsulated wire can have a length of one hundred feet or more, and a grid of wires can be used for detection within an Area of Interest (AOI).
