Abstract:
The invention relates to a dielectric transducer structure comprising a body of elastomeric material that is provided with an electrode arrangement on each of two boundary surfaces lying oppositely to one another. At least one boundary surface comprises a corrugated area that comprises heights and depths. The aim of the invention is to improve the compliance to elastic deformations of the dielectric transducer structure. To this end, the heights and depths are arranged in both perpendicular directions of the boundary surface.
Abstract:
The invention provides an elastomer transducer for converting between electrical energy and mechanical energy. The transducer comprises a composite material with a body (2, 4) and a film (3) of an elastomer material, the body comprising at least an electrically conductive portion and an anisotropic body, in the anisotropic body, fibers are arranged in a pattern to provide inferior flexure resistance and an anisotropic compliance to stretch in a first direction.
Abstract:
The invention provides an elastomer transducer for converting between electrical energy and mechanical energy. The transducer comprises a composite material with a body and a film (3), the body comprising at least an electrically conductive portion and an anisotropic body (2). In the anisotropic body, voids (5, 6) provide an inferior flexure resistance and an anisotropic compliance to stretch in a first direction. The film comprises an elastomer material which could be at least partly embedded in the voids.
Abstract:
The invention provides a transducer for converting between mechanical and electrical energies. The transducer comprises an EAP laminate with a layer (2) of an elastomer material arranged between two electrode layers, each electrode layer comprising a layer (5) of a plastically deformable material, e.g. metal or a thermoplastic material, and a layer (6) of an electrically conductive material. Due to the layer of plastically deformable material, the electrode layers can be shaped into various shapes which can provide anisotropic characteristics of the transducer.
Abstract:
The invention provides a valve with an orifice (6) and a power actuated valve structure (7) for varying a flow area of the orifice. The valve structure provides two way communication so that the orifice may be changed by application of a bias voltage between two conductive layers arranged on opposite sides of a film of a dielectric elastomer material (2), and such that a pressure in the orifice may deflect the film and thereby cause a change in capacitance of the capacitor structure defined by the conductive layers and the film.
