MATRIX ELECTRODE DESIGN FOR THREE-DIMENSIONAL E-FIELD SENSOR

摘要

An electrode arrangement has a transmitting electrode configured to generate a quasi-static alternating electric field which extends into an observation area, a first electrode extending in a first direction and configured to be connected to an evaluation device as a receiving electrode, and a second electrode extending in a second direction different from the first direction wherein for evaluating disturbances of the quasi-static alternating electric field an enhanced sensitivity profile is obtained by combining the first and second electrode.
