1. A bi morph transducer, whose active areas comprise:

  • at least two sheets joined along an interface, one of said sheets being made from a dielectric polymer material carrying an excess of electric charge, andtwo electrodes for creating an electrical field across the thickness of said charged material, wherein the joining of said sheets prevents them from sliding against each other, the elastic characteristics of said sheets being differentiated for causing said active areas to bend under the action of said electrical field;

    one of said electrodes being located at said interface.
