First Claim
Patent Images
1. A composite comprising:
- a film made of a dielectric material and having a first surface and second surface, at least the first surface comprising a surface pattern of raised and depressed surface portions, anda first electrically conductive layer being deposited onto the surface pattern, the electrically conductive layer having a corrugated shape which is formed by the surface pattern of the film;
wherein the second surface is substantially flat.

Abstract
A composite for a transducer facilitates an increased actuation force as compared to similar prior art composites for transducers. In accordance with the present invention, the composite also facilitates increased compliance of the transducer in one direction and an improved reaction time as compared to similar prior art composites for transducers, as well as provides an increased lifetime of the transducer in which it is applied.

36. A composite comprising:
-
a film made of a dielectric material and having a first surface and second surface, at least the first surface comprising a surface pattern of raised and depressed surface portions; and a first electrically conductive layer being deposited onto the surface pattern, the electrically conductive layer having a corrugated shape which is formed by the surface pattern of the film; wherein the surface pattern forms wave crests and troughs extending essentially in the lengthwise direction and wherein the composite is substantially (i.e. at least 10 times) longer in a lengthwise direction than in a perpendicular crosswise direction.
