Abstract

Small-scale electromagnetic soft actuators are characterized by a fast response and simple control, holding prospects in the field of soft and miniaturized robotics. The use of liquid metal (LM) to replace a rigid conductor inside soft actuators can reduce the rigidity and enhance the actuation performance and robustness. Despite research efforts, challenges persist in the flexible fabrication of LM soft actuators and in the improvement of actuation performance. To address these challenges, we developed a fast and robust electromagnetic soft microplate actuator based on a laser-induced selective adhesion transfer method. Equipped with unprecedentedly thin LM circuit and customized low Young’s modulus silicone rubber (1.03 kPa), our actuator exhibits an excellent deformation angle (265.25°) and actuation bending angular velocity (284.66 rad·s−1). Furthermore, multiple actuators have been combined to build an artificial gripper with a wide range of functionalities. Our actuator presents new possibilities for designing small-scale artificial machines and supports advancements in ultrafast soft and miniaturized robotics.

利用飞秒激光制造的高性能液态金属电磁致动器

小型电磁软致动器具有响应速度快、控制简单的特点，在软机器人和微型机器人领域具有广阔的发展前景。使用液态金属（LM）替代软致动器内部的刚性导体，可以降低刚性，提高致动性能和鲁棒性。尽管开展了大量研究工作，但在灵活制造液态金属软致动器和提高致动性能方面仍存在挑战。为了应对这些挑战，我们开发了一种基于激光诱导选择性粘附转移方法的快速、坚固的电磁软微孔板致动器。我们的致动器配备了前所未有的超薄 LM 电路和定制的低杨氏模量硅橡胶（1.03 kPa），具有出色的变形角度（265.25°）和致动弯曲角速度（284.66 rad-s-1）。此外，我们还将多个致动器组合在一起，构建了一个具有多种功能的人工抓手。我们的致动器为设计小型人工机械提供了新的可能性，并为超快软机器人和微型机器人技术的发展提供了支持。
