An electromechanical device comprising: first and second electrodes each comprising a metal layer; an active layer comprising at least one ferroelectric polymer and disposed between the first and the second electrode. The first electrode and the second electrode each comprise an interface layer comprising poly(3,4-ethylenedioxythiophene). Each interface layer is interposed between the active layer and the corresponding metal layer. The invention further relates to a method for manufacturing such a device.
