Abstract
The invention relates to an arrangement for detecting body parts by absorbing an electric near field. Various, particularly capacitive methods exist for detecting an approaching human body. Most of said methods operate on the principle that an electrode emits an alternating electric field, the distribution of which changes towards the environment when a body or body part approaches, and said change is detected by means of suitable electronics. The detection arrangement according to the invention is used for detecting objects, particularly moving limbs, that approach or are present in an observation zone and comprises a transmitter electrode device for inducing an alternating electric field in the observation zone or the surrounding area thereof, a receiver electrode device for detecting an electric field in the observation zone or said surrounding area, and an isolating electrode device for shielding part of the field that extends between the transmitter electrode and the receiver electrode.
