Abstract

Robots have a profound impact on human production and life, which have been developed by leaps and bounds in recent decades. As the higher and higher requirements for operations in complex environments, researchers continue to develop wireless driven miniature robots. In this paper, the ratio and deformation properties of PNIPAM and PEGDA hydrogels were researched, and the microcrawls and microgrippers with 3D structure were prepared through secondary curing technology. They have light stimulus response and magnetic response characteristics, and can be reversibly transformed from 3D to 2D structure to complete crawling and transportation functions. This research offers a reference for the fabrication and programmable actuation of intelligent materials. It holds certain promise in the domains of transportation and bionics.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
