Inchworm biomimetic structure and manufacturing process based on magnetically driven flexible thin film actuator

Abstract

An inchworm biomimetic structure and manufacturing process based on a magnetic-driven flexible thin-film driver. The flexible film driver and the foot structure are bonded to the silicone mold through adhesive materials, and the magnetic poles of the magnetically driven flexible film driver on the head and abdomen are opposite; the manufacturing process is to first prepare the silicone film, then prepare the foot structure, and then Carry out the preparation of the magnetically driven flexible film driver, and finally prepare the bionic structure of the inchworm; the present invention utilizes the magnetic drive characteristics of the magnetically driven flexible film driver to realize the controllable driving of the inchworm-like structure under the control of the magnetic field, and its manufacturing process adopts a photolithography-based , molding and spin-coating techniques, to achieve accurate and controllable manufacturing of some structures, and to realize the organic unity of simple driving conditions, rapid response and large deformation.

Description

technical field [0001] The invention belongs to the technical field of bionic manufacturing in micro-nano engineering, and in particular relates to a bionic structure and manufacturing process of an inchworm based on a magnetically driven flexible film driver. Background technique [0002] The thoracic and caudal feet of the inchworm can tightly grasp the attachment surface without damaging the attachment surface, and have high adaptability to the material and shape of the attachment surface; Quickly and freely switch between types to provide driving force for crawling; inchworms rely on two pairs of feet and trunks to achieve arbitrary climbing and walking on branches and trunks, with high mobility and good concealment; many advantages make inchworms a Key research objects in the field of bionic soft robotics research. [0003] At present, the mainstream drive methods used in the bionic field of inchworms are electric drive and thermal drive. Among them, the electric driv...

Problems solved by technology

Among them, the electric driving method mainly uses two kinds of driving materials, ionic electroactive polymer and non-ionic electroactive polymer. The ionic electroactive material needs to be packaged before driving, which reduces its flexibility and is not conducive to deformation; Active polymers often require high driving voltage, which greatly limits their application range

The thermal driving method relies on the driving force generated by the thermal deformation of the driving material, so the response is slow
