Electrically driven artificial muscle and preparation method thereof

Abstract

The invention discloses an electrically driven artificial muscle and a preparation method thereof. The electrically driven artificial muscle is based on liquid metal and comprises liquid metal flexible electrodes capable of being sprayed or printed, electroactive polymer materials and flexible packaging materials; the liquid metal flexible electrodes are arranged on the surfaces of the electroactive polymer materials and include the positive electrode and the negative electrode; and the liquid metal flexible electrodes and the electroactive polymer materials are wrapped with the flexible packaging materials, so that the liquid metal flexible electrodes are protected. The electrically driven artificial muscle can bend or deform in other modes under the effect of an extra electric field; compared with an existing artificial muscle structure made of platinum or golden materials, the process steps of the scheme provided by the invention are fewer, cost is lower, and no dangerous compound is needed; and the electrically driven artificial muscle has broad application in the fields of medical instrument designing, industrial product manufacturing, robot and the like.

Description

technical field [0001] The invention belongs to the technical field of artificial muscles, and in particular relates to an electrically driven artificial muscle and a preparation method thereof. Background technique [0002] By simulating the movement of organisms, achieving high efficiency and high flexibility in engineering design has always been a hot spot in the field of mechanical engineering. Most of the various movement modes of organisms are realized through muscle contraction and stretching, so artificial muscles have become one of the hot areas in scientific research. Similar to the muscle tissue of a living body, the most important feature of the artificial muscle is that it can produce bending or contraction movement under the action of external electrical excitation, and output a certain force while generating deformation, and place the artificial muscle at the joint of the machine that needs to move , with the control module, it can realize the set action or c...

AI Technical Summary

Problems solved by technology

[0007] The traditional ionic polymer-metal composite materials need to use materials such as platinum or gold and their compounds to make artificial muscles. The method of chemical deposition is relatively complicated, and the heating and other operations involved in the process are also dangerous.
