Elastomer membrane enhanced electrostatic transducer
First Claim
1. A transducer, comprising:
- (a) opposed first and second conductive plates for application of an electrical potential therebetween; and
,(b) an elastomeric dielectric material disposed between said plates and in contact therewith;
said dielectric material having a plurality of pockets of approximate average depth "d" such that, for a gas existing within said pockets at a pressure "P", the product Pd is significantly less than the value required to achieve the minimum breakdown voltage of said gas.

Abstract
A transducer having opposed first and second conductive plates for application of an electrical potential difference therebetween. An elastomeric dielectric material such as neoprene rubber is disposed between the plates and in contact therewith. The dielectric material has a plurality of pockets of approximate average depth "d" such that, for a given gas maintained within the pockets at a pressure "P", the product Pd is significantly less than the value required to achieve the minimum breakdown voltage for the gas in the pockets. Alternatively, the elastomeric dielectric material disposed between the plates may take the form of a plurality of strips or nodules which separate the plates by a distance "d" as above.
