Abstract

The invention relates to a nano manipulator, which comprises a base body and a clamping structure, the clamping structure comprises two nanometer fiber actuators, the two nanometer fiber actuators are arranged on the base body in a spaced mode, and each nanometer fiber actuator comprises a composite structure body and a vanadium dioxide layer. The composite structure body comprises a carbon nanotube line and an aluminum oxide layer, the aluminum oxide layer coats the surface of the carbon nanotube line and is coaxially arranged with the carbon nanotube line, the vanadium dioxide layer coats the surface of the composite structure body, and the vanadium dioxide layer and the composite structure body are not coaxially arranged.

Description

technical field [0001] The invention relates to a nano manipulator, in particular to a nano manipulator based on carbon nanotubes. Background technique [0002] The working principle of the actuator is to convert other energy into mechanical energy. There are three ways to achieve this conversion: through electrostatic field into electrostatic force, that is, electrostatic drive; through electromagnetic field into magnetic force, that is, magnetic drive; using materials Thermal expansion or other thermal properties effect the conversion of energy, ie thermal actuation. [0003] Actuators that convert energy using the above-mentioned thermal drive are thermal actuators. Existing thermal actuators are usually polymer-based film-like structures, which can be actuated by raising the temperature of the polymer through an electric current and causing significant volume expansion. The principle of thermally actuated devices dictates that electrode materials must possess good elec...
