A process for manufacturing an electrochemical transducer, having at least one active element in the form of at least one film of a polymer material, comprises the following steps. First, clamping a polymer film between an inner set of jaws for delimitating a central area. Second, further clamping said polymer film between an outer set of jaws for delimitating a peripheral area surrounding the central area. And finally, shaping at least one of the areas by stretching.

A process for manufacturing an electromechanical transducer having at least one active element in the form of at least one film of a polymer material shaped so as to have a spherical skullcap at its center and at the periphery of the spherical skullcap the film is shaped as a truncated cone with rectilinear generatrices along the marginal radii of the spherical skullcap, said process comprising: clamping said polymer film between an inner set of jaws for delimitating a central area; further clamping said polymer film between an outer set of jaws for delimitating a peripheral area surrounding said central area; stretching said peripheral area by moving said inner set of jaws in relation to said outer set in order to form said truncated cone shape; and shaping said central area by driving a punch towards said central area in order to form said spherical skullcap.
