Remote Magnetomechanical Nanoactuation.

A novel approach to nanoactuation that relies on magnetomechanics instead of the conventional electromechanics utilized in micro and nanoactuated mechanical systems is devised and demonstrated. Namely, nanoactuated magnetomechanical devices that can change shape on command using a remote magnetic external stimulus, with a control at the subnanometer scale are designed and fabricated. In contrast to micro and nanoactuated electromechanical systems, nanoactuated magnetomechanical remote activation does not require physical contacts. Remote activation and control have a tremendous potential in bringing vast technological capabilities to more diverse environments, such as liquids or even inside living organisms, opening a clear path to applications in biotechnology and the emerging field of nanorobotics.
