<p>In an evaluation method for a capacitive contact sensor with at least one transmitting and at least one receiving electrode, which are able to be brought into a capacitive coupling, at the at least one receiving or sensor electrode a measurement signal is tapped, which represents the temporal course of the coupling capacitance between the at least one transmitting electrode and the at least one receiving electrode and the temporal course of the capacitive load of the sensor electrode, respectively, a reference signal is created from the measurement signal, and at least one detection signal is created, when the reference signal meets at least one detection criterion. An evaluation device may be coupled with at least one transmitting electrode and at least one receiving electrode or with at least one sensor electrode of the capacitive contact sensor and is adapted to carry out the above evaluation method.</p> |
