Special Issue Information

Dear Colleagues,

This Special Issue aims to explore the latest advancements in the synthesis and characterization of hybrid hydrogels, which have emerged as versatile materials with a wide range of applications across fields such as biomedicine, tissue engineering, and environmental science or agriculture. Contributions that highlight novel synthesis techniques, including the generation of bioinspired hybrid hydrogels that are incorporated with functional additives to enhance their performance, are of significant interest. This Special Issue welcomes colleagues from the field of polymer and materials science to present original experimental studies or review papers; these can include synthesis studies, research on physico-chemical, mechanical, morphological, and drug or fertilizer release, as well as studies on biological characterization.

Papers that present recent developments in the synthesis and characterization of hybrid hydrogels using radiation processing, a technique that enables precise control over hydrogel properties to be achieved, are also welcome. Studies involving environmentally friendly hybrid hydrogels that encourage the sustainable development of agriculture may also be included in this Special Issue.

Abstract
Magnetic hydrogel soft robots have shown great potential in various fields. However, their contact dynamic behaviors are complex, considering stick–slip motion at the contact interface, and lack accurate computational models to analyze them.

Magnetic hydrogel soft robots have shown great potential in various fields. However, their contact dynamic behaviors are complex, considering stick–slip motion at the contact interface, and lack accurate computational models to analyze them. This paper improves the numerical computational method for hydrogel materials with magneto-mechanical coupling effect, analyses the inchworm-like contact motion of the biomimetic bipedal magnetic hydrogel soft robot, and designs and optimizes the robot’s structure. In the constitutive model, a correction factor representing the influence of the direction of magnetic flux density on the domain density has been introduced. The magnetic part of the Helmholtz free energy has been redefined as the magnetic potential energy, which can be used to explain the phenomenon that the material will still deform when the magnetic flux density is parallel to the external magnetic field. The accuracy of the simulation is verified by comparing numerical solutions with experimental results for a magnetic hydrogel cantilever beam. Furthermore, employing the present methods, the locomotion of a magnetic hydrogel soft robot modeled after the inchworm’s gait is simulated, and the influence of the coefficient of friction on its movement is discussed. The numerical results clearly display the control effect of the external magnetic field on the robot’s motion. Full article
