Abstract
The present invention provides a self-sensing tweezer device for micro and nano-scale manipulation, assembly, and surface modification, including: one or more elongated beams disposed in a first configuration; one or more oscillators coupled to the one or more elongated beams, wherein the one or more oscillators are operable for selectively oscillating the one or more elongated beams to form one or more “virtual” probe tips; and an actuator coupled to the one or more elongated beams, wherein the actuator is operable for selectively actuating the one or more elongated beams from the first configuration to a second configuration.

A device for micro and nano-scale manipulation and assembly, comprising:
- one or more elongated beams disposed in a first configuration;
- one or more oscillators coupled to the one or more elongated beams, wherein the one or more oscillators are operable for selectively oscillating the one or more elongated beams;
- and
- an actuator coupled to the one or more elongated beams, wherein the actuator is operable for selectively actuating the one or more elongated beams from the first configuration to a second configuration;
- wherein the one or more elongated beams each comprise a tip portion that, when oscillated, defines a “virtual” probe tip of the elongated beam, wherein a shape of the “virtual” probe tip is defined by both a characteristic shape of oscillation of the tip portion and a geometry of the elongated beam.
