Problems solved by technology

A.Cirillo and others introduced an artificial skin film based on photoelectric technology, which can detect external forces in different directions such as normal and tangential directions, but it is the same as the first sensing film material, and can only detect the average force in a small area. Stress/strain, but cannot reflect the distribution of stress/strain in a large area and its change with time

Abstract

The invention provides flexible and elastic intelligent metal rubber based on gold nanoparticle-polyethylene and a preparation method of the rubber. The metal rubber consists of a polyethylene layer and a gold nanoparticle layer, wherein the polyethylene layer and the gold nanoparticle layer are alternately overlapped and closely and vertically arranged, the gold nanoparticle layer consists of spherical gold nanoparticles, and the particles are in conductive contact through electronic tunneling; the polyethylene layer is made of low-density polyethylene. According to the flexible and elastic intelligent metal rubber based on gold nanoparticle-polyethylene and the preparation method of the rubber, an ultrathin film can be prepared and can perceive film surface compressive stress/ strain, internal stress/strain distribution of a film coverage area and the capacity of the film with the change of time. Meanwhile, the film has good flexibility, can be better attached to a 3D curved surface, can work normally under a repeated deformation condition, has good stability and can still keep good elasticity, conductivity and resistance sensitivity to strain under the repeated deformation condition.
