ABSTRACT:
A woven mesh of conductively coated stiff filaments is affixed between a first element deformable in response to an applied electronic signal and a second element which has substantially the same configuration as the first element and which may be electrically deformable also. The mesh serves as a center vane between two elements which allows the bender elements to move relative to each other. The bender is supported by peripheral tabs extending from the mesh. A bender structure is produced by coating a woven mesh of conductively coated filaments with an uncured solid epoxy. The mesh and two transducer elements are assembled together and heat and pressure applied to melt and then cure the epoxy, causing the conductive mesh material to make contact with and adhere to the faces of the transducer elements.
