Abstract

Eine Vorrichtung zur Erfassung eines Objekts umfasst eine Spule zur Erzeugung eines magnetischen Feldes im Bereich der Spule, eine erste Elektrode zur Erzeugung eines elektrischen Feldes im Bereich der Elektrode und eine Auswerteeinrichtung zur Erfassung des Objekts auf der Basis einer Beeinflussung des magnetischen Feldes oder des elektrischen Feldes. Dabei ist eine Trenneinrichtung zum Unterbinden eines Stromflusses durch die Spule vorgesehen, um als Elektrode die Spule zu nutzen.
