A multilayer composite and a method of making such

摘要

The invention provides a multilayer composite which comprises at least two composites. Each composite comprises a film made of a dielectric material and having a front surface and rear surface. The front surface comprises a surface pattern of raised and depressed surface portions. Furthermore, each composite comprises a first electrically conductive layer being deposited onto the surface pattern. The electrically conductive layer has a corrugated shape which is formed by the surface pattern of the film. The multilayer composite can be utilised for conversion between electrical and mechanical energies and can therefore be used as a transducer.
