Bending transducer as an actuator, bending transducer as a sensor, bending transducer system

The invention relates to a bending transducer operated as an actuator, comprising a deflectable element, a micro-electromechanical transducer which extends along a centroidal line of the deflectable element and deflects the deflectable element in a first direction (161, 161b) when a first electrical signal is applied, and a second micro-electromechanical transducer which extends along the centroidal line and deflects the deflectable element in a second direction opposite the first direction when a second electrical signal is applied, wherein the centroidal line is located between sides of the first and the second micro-electromechanical transducers facing away from one another, and an electrical controller which is designed to modify the first electrical signal and the second electrical signal according to an input signal, such that a changing of the first electrical signal and a changing of the second electrical signal takes places in accordance with the electrical input signal, and the phases of the first and second electrical signals are shifted relative to one another. The invention also relates to a bending transducer operated as a sensor.
