SENSOR, SENSOR NETWORK, SEAT AND METHOD FOR THE DETECTION OF TRAIN SEAT OCCUPANCIES

摘要

The invention concerns a sensor for determining the occupancy of a seat (22) in a railway vehicle. It is proposed that the sensor comprises a switch (10), a piezoelectric element (12) being part of the switch (10) or being attached to the switch (10) and a wireless transmitter (14) which is designed for data transmission by using an electrical energy produced by the piezoelectric element (12).
