Abstract (en)
[origin: WO2008135696A2] The invention relates to a device for an automobile, the device including a membrane used both as an actuator and a sensor. The device is to be integrated in a member of the vehicle bodywork. It comprises an outer wall (4) defining an opening (6), a chamber (2) having a variable volume, and at least one membrane (8) capable of being moved by a reaction of the material of which the membrane (10) is made to the application of an electric voltage. The membrane (8, 10) is used both as an actuator and a sensor.
