Problems solved by technology

However, the current research is mainly based on the deformation of the film produced by photobending, which is then used as the power of the actuator. Usually, the lighting device is also an additional platform, so that the integration and miniaturization of photobending actuators or robots cannot be truly realized.
[0005] So far, there have not been any related reports on conductive substrates based on photobendable polymer materials.

Abstract

The invention discloses a photoinduced bending flexible electro-conductive baseplate and a preparation method thereof. The photoinduced bending flexible electro-conductive baseplate comprises a photoinduced bending flexible substrate and an electro-conductive layer, wherein the photoinduced bending flexible substrate is made of a photoinduced bending polymer material, and the electro-conductive layer is attached onto the surface of the photoinduced bending flexible substrate. The flexible baseplate simultaneously having the photoinduced bending capability and the electro-conductive capability is prepared, so that the integration and the microminiaturization of a photoinduced bending actuator and a light source can be realized, and the wide application and the quick development of a photoinduced bending material in the field of artificial muscles can be accelerated.

Description

technical field [0001] The invention belongs to the field of bionic technology, and in particular relates to a photoinduced bending flexible conductive substrate and a preparation method thereof. Background technique [0002] Since the middle of the 20th century, people have become more and more aware of the importance of the inspiration of nature for the development of new materials and technologies, thus proposing the concept of bionics and establishing the discipline of bionics. With the development of research, bionics has become a frontier and focus of natural science. Since the beginning of the 21st century, with the continuous deepening of robot development and people's strong demand for intelligent mechanical systems, artificial muscles, which are the key to driving robots and intelligent mechanical systems, have become the focus of bionics research. Muscle is a biologically contractile tissue with the functions of information transmission, energy transmission, wast...
