Abstract

A sensor system (20; 200; 300; 400; 500) accurately measures, with a high level of sensitivity, one or more vector components of a small electric field, through the use of multiple, relatively fixed sensors (30, 31; 230, 231; 330, 331; 430, 431; 530, 531), at least one of which constitutes a weakly coupled capacitive sensor (31; 231; 331; 431; 531). The sensor system (20; 200; 300; 400; 500) enables the electric field to be determined in a direction normal to a surface or along multiple orthogonal axes. Measurement of the electric field vector can provide improved resolution and characterization of electrical signals produced, for example, by organs within the human body (10).
