A sensor measuring by capacitance, in particular for the detection of a trapping of objects or body parts by motor driven devices, comprising an arrangement of a number of electrodes on a support and means of measurement of a capacitance or a capacitance change, is disclosed. The sensor is of a planar film-like embodiment with a support made from a film material for the arrangement of the electrodes. Furthermore, a capacitive sensor system, for detection of a clamping situation of objects or body parts with motor driven devices having several sensors of the above type, is disclosed, whereby on an activation of several of the sensors a trapping situation is recognised. |
