Abstract

Three-dimensional micro devices usable as electromagnetic and magnetomechanical energy converters, as micromagnetic motors or generators, and methods for their production. The three-dimensional micro devices exhibit high efficiency even at dimensions on the microscale and below, and the method for production, as well as mass production, is simple and economical. Moreover, the three-dimensional micro devices at least include one three-dimensional device produced using roll-up technology. This three-dimensional device includes all functional and structural components for full functionality. At least one functional or structural component is an element that is at least partially freely movable at least partially within a surrounding element and is arranged such that it can be rotated at least around one of its axes.
