摘要 |
A tactile capacitive sensor (11,13,24,30) is disclosed, in particular for detecting an obstacle in the path of an actuating element (7) of a vehicle (1), which comprises an inner electrode (15,25) that can be set to a measurement potential, a screen electrode (16,26) that can be charged to a ground potential, separated from the inner electrode (15,25) by an elastic, electrically insulating material (18), and an analysis circuit (42) connected to the inner electrode (15,25) for detecting a capacitance between the inner electrode (15,25) and the screen electrode (16,26). Such a sensor has a low sensitivity to external interference fields. |
