The invention relates to a microelectromechanical drive for moving an object, having electrostatic bending actuators, wherein each electrostatic bending actuator has a cantilever having at least one active element which has a layer stack forming at least one capacitor positioned offset to a center-of-gravity-plane of the cantilever which leads alongside a longitudinal axis of the cantilever from a supported end of the cantilever to a loose end, which is averted from the supported end of the cantilever and which has a contact area for engaging with the object.The microelectromechanical drive can be used to displace any target objects from nanoscopic to macroscopic sizes that are within the force-displacement configurations of the electrostatic bending actuators. The microelectromechanical drive is suited to act as an inchworm drive.
