  • Electroactive polymer transducer
    Patent number: 7969070
    Abstract: An electroactive polymer transducer comprising a membrane formed of an approximately rectangular electroactive polymer portion surrounded by two electrodes, at least two points of the membrane being connected to rigid supports, and comprising at least one deformable element for limiting the deformations that the membrane may undergo, the limiting element having a meandering form and being connected to the membrane in several approximately distributed points.
