    摘要: Polymer blends having improved electromechanical responses and mechanical properties for use in electromechanical application are disclosed. In particular, polymer blend including at least one electrostrictive terpolymer, e.g., poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) (P(VDF-TrFE-CFE)) or a derivative thereof, and at least one fluoropolymer, e.g., PVDF or derivative thereof such as PVD-TrFE are disclosed. The polymer blends advantageously have a transverse strain, i.e., a strain perpendicular to the applied electric field direction, that is about 1.5% or higher (as measured at 100 MV/m) while also having an elastic modulus of no less than about 400 MPa (as measured at 30° C. and 1 Hz by dynamic mechanical analyzer).

    摘要: An adaptive lens comprises an actuator and a lens, the lens being mechanically coupled to the actuator so that energization of the actuator adjusts a focal point of the lens. The actuator may comprise a multilayer stack of electromechanical polymer (EMP) layers, having electrodes configured to apply an electric field across each EMP layer. The actuator may be operable to move and/or deform a lens, so as to adjust the focus properties of the lens. In some examples, the actuator has an annular shape, supporting a lens within the inner radius of the annulus. The lens position may be adjusted in an axial direction. In other examples, the actuator may be mechanically coupled a surface of a deformable lens, either directly or through another element of a lens structure. A strain applied to the lens modifies a curved surface of the lens, hence modifying the focal length of the lens.
