DEVICE FOR DETECTING AT LEAST ONE BODY PART OF A PERSON IN A DEFINED LOCATION

摘要

The invention relates to a device for detecting at least one body part of a person in a defined location, comprising at least two ultrasound-based sensors, the distance of an object to the sensor being determinable by means of the ultrasound-based sensors and the distances determined by the sensors being usable to determine the position of the object, or at least one pressure-sensitive sensor which detects the pressure exerted by a body part. Each ultrasound-based sensor or pressure-sensitive sensor comprises an electromechanical film, a grounded electrode being applied to one side of the electromechanical film and a sensor electrode being applied to the side of the electromechanical film opposite the grounded electrode.
