Abstract
A three-dimensional (3D) untethered mobile actuator having the following parts: (a) a substrate having two or more magnetized panels, and (b) a frame that connects the magnetized panels, the magnetized panels being made of a polymer with embedded permanent magnetic particles, each magnetized panel of the 3D untethered mobile actuator having a magnetic moment in a different direction than a next neighboring panel, and the 3D untethered mobile actuator having a structural configuration that changes between a substantially flat structural configuration in the absence of a magnetic field, and an actuated structural configuration when under influence of a magnetic field. Methods of manufacturing and using the 3D mobile actuator and a system that includes the 3D mobile actuator are provided.
