Sensor system for measuring an electric potential signal of an object

摘要: The invention generally pertains to reducing artifact noise signals present when non-invasive capacitive-type signal measurements are taken of static electric fields produced by an object (10) interest. According a first preferred embodiment the invention, given is reduced minimizing potential difference between ground point (G1) sensor circuitry and (10). second change in due motion (30, 40; 30', 40'; 230; 330; 430; 530; 630) field minimized impact changes coupling source.
