Embodiment 1

[0048] A bionic micro-clamp driven by vascularized artificial muscles, including a bionic micro-clamping mechanism 1, a vascularized helical artificial muscle 2, an electrode assembly 3, a concave base 4 and a cell culture solution 5;

[0049] The material used in the bionic micro-clamping mechanism 1 is SU-8 (3050), and the SU-8 (3050) layer with a thickness of 500 microns is formed according to the two-dimensional in-plane shape of the micro-clamping mechanism through a standard soft photolithography process. Cured on thin glass (thickness: 0.1 mm). Then the thin glass is peeled off to form a three-dimensional bionic micro-clamping mechanism 1 .

[0050] Described bionic micro-clamping mechanism 1 is made up of U-shaped section 11 and bionic micro-clamp arm section 12, and the bottom of U-shaped section 11 is a semicircular ring structure, and the inner radius of the ring is 750 microns, and the ring width (outer diameter minus inner diameter) size) is 700 microns. Two arm...

Abstract

The invention relates to a bionic micro clamp based on vascularized spiral artificial muscle driving, and belongs to the technical field of artificial micro clamp devices. The bionic micro clamp comprises a bionic micro-clamping mechanism, a vascularized spiral artificial muscle, an electrode assembly, a concave base and a cell culture solution, the bionic micro-clamping mechanism is composed of aU-shaped section and a bionic micro-clamp arm section, the bottom of the U-shaped section is fixed in the concave base, and the bionic micro-clamp arm section extends out from the top of the U-shapedsection; grooves are symmetrically formed in the two sides of the U-shaped section; the vascularized spiral artificial muscle is formed by winding microfibers in the grooves; biological microfibers and micro-channels are arranged in the microfibers; skeletal muscle cells are wrapped in the biological microfibers, and the electrode assembly provides voltage for the skeletal muscle cells; and during use, the cell culture solution is injected from ends of the microfibers and flows out from the other ends of the microfibers. The micro clamp supplies nutrition to skeletal muscle cell populations in a perfusion mode through the micro-channel and drives the bionic micro-clamping mechanism to be opened / closed by electrically stimulating the skeletal muscle cell populations to expand / contract.

Description

technical field [0001] The invention relates to a bionic micro-clamp driven by vascularized spiral artificial muscles, which belongs to the technical field of artificial micro-clamp devices. Background technique [0002] Micro pincers are one of the common structures of shrimps, crabs, scorpions and other organisms in nature. Hundreds of millions of years of evolution have given the micro pincers of the above-mentioned organisms the advantages that current artificial systems cannot match, such as small size but high energy conversion efficiency Wait. Although the current artificial micro-clamp device has high operating precision, the internal operation mechanism is still mainly purely mechatronic. Miniaturization of the overall device is realized. [0003] In order to further improve the energy conversion efficiency of mechatronic micro-tweezers and at the same time realize the micro-bionic structure of artificial micro-tweezers, the research of life-like tweezers is curre...
