1. A method for fabricating electroactive polymer transducers, the method comprising:

  • providing an electroactive polymer film comprising an elastomeric dielectric polymer having an elastic modulus of less than about 100 MPa;

    forming an array of electrodes on the electroactive polymer film;

    sandwiching the electrode array between a top and bottom array of frame components to form an array of electroactive polymer transducers; and

    applying an array of negative spring rate biasing mechanisms onto the array of electroactive polymer transducers,wherein the array of negative spring rate biasing mechanisms are configured to impose a negative spring rate bias on the electroactive polymer film, andwherein the negative spring rate biasing mechanisms comprise a central hub mechanically coupled to an output disc and two opposing leaf spring flexures extending between the central hub and a frame side of an electroactive polymer transducer.
