Abstract

1418673 Electrostrictive transducers RION KK 4 Dec 1972 [3 Dec 1971] 55945/72 Heading H4J A mechanical to electrical transducer element 10 comprises a body of a vulcanized elastomer having mixed therewith an electrically conductive material in distributed form. The elastomer is selected from chloroprene rubbers, nitrile rubbers, isoprene rubbers, chlorosulphonated polyethylene elastomers fluoro-elastomers, which all include polar substituents in the side chains thereof, and butadiene elastomers having no polar substituents in the side chains thereof. The electrically conductive material may be carbon black or graphite. Specifically the conductive material is channel black or furnace black in an amount of 5 to 40 parts per 100 parts by weight of the elastomer. When such transducer elements have a field of 300 volt A.C. applied across them they exhibit electrostrictive properties. One such element is shown (Fig. 1) used in a mechanical to electrica 1 transducer. A brass HT electrode 12 is attached to one face of the transducer element and this electrode is insulated by a block 14 from a metallic shield 18 which acts as the second electrode of the transducer. A damper element 20 of for example foamed urethane covers part of the shield 18 and acts as a contact surface for a mechanical force applied in the direction A. An A.C. output voltage is generated at terminals 22 in response to such an impact. Fig. 2 (not shown) illustrates a similar transducer which acts as a vibration pick-up device. Such transducers may be used as electrical to mechanical transducers.
