ABSTRACT:
A pressure sensitive field effect semiconductor device, which may be employed as a contactless switch is disclosed. The device employs at least one layer of an elastomer material which is also an electret to effectuate the conversion of a longitudinal pressure variation to an electrical variation and to create an electric field which regulates the conductivity of the current carrying channel.
