本文报道了一种用于凝胶片的精细磁性图案化工艺。最近，已经开发了韧性凝胶材料，其被称为双网络凝胶（DN-凝胶）。作者采用了一种非常强硬的DN-凝胶软致动器分散精细的磁性颗粒。该材料不仅具有较高的强度和延伸率，而且具有较高的抗剪切强度。作者还提出了一种新的工艺，利用激光局部加热的磁性微图案化过程中的这种材料。分辨率比报道的传统磁性软致动器更精细。我们对凝胶材料进行了拉伸试验，并显示了机械性能。我们还尝试在磁性凝胶片上扫描激光，以获得磁各向异性的微观图案。最后，我们展示了爬行运动的磁性图案化的凝胶片。
This paper reports a fine magnetic patterning process for a gel sheet. Recently, tough gel materials have been developed which are known as double-network gels (DN-gels). Authors employed an extremely tough DN-gel for soft actuators by dispersing fine magnetic particles. The proposed material showed not only high strength and large elongation but also high anti-cutting strength. Authors also proposed a new process for a magnetic micro patterning process for this material using local heating by laser. The resolution was finer than reported conventional magnetic soft actuators. We performed tensile tests of the gel material and showed mechanical properties. We also tried to scan laser on a magnetic gel sheet for micro patterning of the magnetic anisotropy. Finally, we demonstrate crawling motion of a magnetic patterned gel sheet.
