Abstract

Abstract Soft actuator is widely applied in soft grasp and artificial actuation. However, the characteristics of fast response and precise controllability are challenges for soft actuators. In this report, an ultrafast response and precisely controllable soft electromagnet actuator based on Ecoflex rubber film filled with neodymium-iron-boron is proposed. After optimizing the matrix and size of the actuator, the flexible magnetic actuator shows many merits including ultrafast response (<0.1 s), large elongation (<120%), excellent working stability, precision for long time working and customized designs. Based on customized patterns, different kinds of grippers have been made and they can realize the function of grasp and clutching of spherical and cylindrical objects. Furthermore, this actuator can be used on designed devices to build a pump system which can implement liquid injection and liquid blend. The proposed soft actuator has a great prospect in the practical application such as medical devices and soft robotics.
