Motor vehicle impact sensor, especially suited to detection of an impact with a pedestrian, comprises foam whose conductivity changes when compressed and that is integrated into the vehicle bumper or bodywork
Motor vehicle impact sensor, especially suited to detection of an impact with a pedestrian, comprises foam whose conductivity changes when compressed and that is integrated into the vehicle bumper or bodywork
Impact sensor has a compressible medium (1) the conductivity of which varies with compression. Thus the impact sensor output signal changes in proportion to the change in conductivity of the compressible medium in a manner that is characteristic of the impact force.
