Abstract
1,105,206. Pressure sensitive devices. TELEFONAKTIEBOLAGET L. M. ERICSSON. 25 May, 1966 [25 May, 1965], No. 23491/66. Heading H1K. [Also in Divisions G1 and H4] A pressure-sensitive device comprises an insulated gate field effect transistor the insulated gate region comprising a piezo-electric layer and a normal dielectric layer so that stress on the piezo-electric layer can exert field effect conductivity control on the channel. Fig. 2 shows a high resistivity P-type silicon substrate containing source and drain N-type regions with electrodes S and D; an oxide layer 7 overlies the source-drain channel and a piezo-electric layer 9 of lead-zircon-titanate or barium titanate with electrode G extending over the oxide layer. A pin K is used to apply pressure to piezo-electric layer 8, the resulting electric field exercising field effect control over the source-drain current. The device may be encased in a sealed casing with pin K in contact with a diaphragm either directly or via a spring or " bouncing putty " (i.e. material with time dependent elasticity properties), and may be used as a microphone or pressure transducer. In a further embodiment a resilient arm co-operates with pin K to provide a pressure controlled switch. The piezo-electric layer may be vaporized on to the dielectric layer or a thin tablet of the material may be glued thereto.
