A bending transducer includes a deflectable element, a microelectromechanical transducer extending along a centroid fiber of the deflectable element deflecting the deflectable element in a first direction when a first electrical signal is applied, and a second microelectromechanical transducer extending along the centroid fiber deflecting the deflectable element in a second direction opposite to the first direction when a second electrical signal is applied, the centroid fiber being located between sides of the first and second microelectromechanical transducers facing away from each other, and an electrical control configured to vary the first and second electrical signals depending on an input signal such that a change of the first electrical signal and a change of the second electrical signal depends on the electrical input signal, and the phases of the first and second electrical signals are shifted relative to each other. A bending transducer operated as sensor is also presented.
