Abstract
An occupancy sensor has three layers. The bottom layer contains two electrodes, and a resistive element between the electrodes. The middle layer is a spacer. The top layer is a third electrode, divided into two parts. When a person sits on the sensor, both parts of the third layer contact the resistive element. This causes current to flow through all of the electrodes. Accordingly, occupancy can be detected by measuring current flow through the electrodes. The device additionally provides heating via the resistive element. The sensor can be arranged in a vehicle seat.
