CAPACITIVE SENSOR FOR A COLLISION PROTECTION DEVICE

摘要

The invention relates to a capacitive sensor (2) for detecting an object, in particular for detecting the event of a collision in a mobile vehicle part. The sensor (2) comprises an electrode array (4) having at least one sensor electrode (6). The sensor (2) further comprises a signal generating circuit (7) located upstream of the at least one sensor electrode (5) for generating a transmission signal (SE), wherein the signal generating circuit (7) generates the transmission signal (SE) as a pulse signal having a trapezoid or triangular temporal pulse shape.
