The invention relates to bimorph electromechanical transducers made from polymer material. It specifically relates to a transducer comprising a plurality of superimposed dielectric sheets for forming a bimorph structure, whose deformations are controlled in linear manner by a voltage. None of the sheets is piezoelectric. The linearity of operation is obtained because at least one of the dielectric sheets carries a permanent electric charge. The invention is applicable to the construction of microphones, telephone receivers, loudspeakers, as well as to the construction of optical components, whose precise, small displacements it is desired to control.
