Description

technical field [0001] The invention relates to a nanomanipulator, in particular to a nanomanipulator 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: converting into electrostatic force through electrostatic field, that is, electrostatic drive; converting into magnetic force through electromagnetic field, that is, magnetic drive; Thermal expansion or other thermal properties enable the conversion of energy, ie thermal actuation. [0003] An actuator that uses the above-mentioned thermal drive for energy conversion is a thermal actuator. Existing thermal actuators are usually film-like structures with polymer as the main body, and the temperature of the polymer is increased by electric current and leads to obvious volume expansion, so as to realize the actuation. The principle of thermally actuated devices determines that electro...
