ABSTRACT:
A freely hanging drape sensor distinguishing between weak and strong activation of the sensor includes a piezoresistive cellular material and standoff layer for providing an analog signal correlated with the strength of an activating force, as well as an on-off function. The drape sensor can be used in conjunction with moving objects, such as electrically operated doors to provide safety door edges. Alternatively, the drape sensor can be used as freely hanging curtains to detect objects moving into contact therewith.
