High-throughput fabrication of soft magneto-origami machines

Abstract

Soft magneto-active machines capable of magnetically controllable shape-morphing and locomotion have diverse promising applications such as untethered biomedical robots. However, existing soft magneto-active machines often have simple structures with limited functionalities and do not grant high-throughput production due to the convoluted fabrication technology. Here, we propose a facile fabrication strategy that transforms 2D magnetic sheets into 3D soft magneto-active machines with customized geometries by incorporating origami folding. Based on automated roll-to-roll processing, this approach allows for the high-throughput fabrication of soft magneto-origami machines with a variety of characteristics, including large-magnitude deploying, sequential folding into predesigned shapes, and multivariant actuation modes (e.g., contraction, bending, rotation, and rolling locomotion). We leverage these abilities to demonstrate a few potential applications: an electronic robot capable of on-demand deploying and wireless charging, a mechanical 8-3 encoder, a quadruped robot for cargo-release tasks, and a magneto-origami arts/craft. Our work contributes for the high-throughput fabrication of soft magneto-active machines with multi-functionalities.

High Throughput Fabrication of Flexible Top-Driven Sensing Probe

“…A detailed fabrication process of the FIP is shown in Figure S8 . Here, an efficient process method of high-throughput fabrication [ 41 ] was developed that can acquire a large number of different experimental samples in a short period of time. By the above preparation process, a large number of FIPs with different magnetic response properties can be fabricated.…”

4D Printing of Humidity‐Driven Seed Inspired Soft Robots

“…The emerging field of soft robotics has attracted increasing attention for its ability to build shape-changing intelligent machines, DOI: 10.1002/advs.202205146 taking advantage of the adaptability and deformability properties of the materials involved. [1][2][3][4][5][6][7][8] In environmental applications, a soft robot should be able to move, grow and/or evolve, adapting its morphology to the environmental stimuli and biodegrade at the end of its life cycle. [9,10] Furthermore, the increase in energy demand in the field of robotics requires a new class of Embodied Energy autonomous robots, [11] which use environment renewable energy to perform their functions with spatialtemporal continuity.…”

Bio-inspired magnetic-driven folded diaphragm for biomimetic robot

“…Apart from the advanced magnetic property designs, the advanced magnetic stimuli, such as the rotational magnetic field and robot-controlled electromagnet, have been made effort to conduct the locomotion of magnetically soft robots 33 – 35 . Meanwhile, many kinds of magnetic-driven soft actuators have been reported, including the origami structure 22 , 30 , 36 – 38 , but most of them can only achieve the changes in shapes 30 , angles 36 , and/or lengths 38 , and cannot realize the relatively large inside-volume changes with high strength, which may limit their potential practical application as soft actuators (drivers), such as the micro-pump. Besides, to mimic the deformation of some tissue species, such as the heart and muscle, their surface should be expanded or compressed during the deformation process 39 , 40 .…”
