Abstract

A sensor device includes a first electrode and a first signal generation device configured to apply an electrical signal to the first electrode such that the first electrode emits a first electrical field. The sensor device further includes a second electrode located at a first distance from the first electrode and configured to pick up the first electrical field. A third electrode and a second signal generation device configured to apply an electrical signal to the third electrode such that the third electrode emits a second electrical field is included in the sensor device.
