Abstract
Integrated printing of magnetic soft robots with complex structures using recyclable materials to achieve sustainability of the soft robots remains a persistent challenge. Here, we propose a kind of ferromagnetic fibers that can be used to print soft robots with complex structures. These ferromagnetic fibers are recyclable and can make soft robots sustainable. The ferromagnetic fibers based on thermoplastic polyurethane (TPU)/NdFeB hybrid particles are extruded by an extruder. We use a desktop three-dimensional (3D) printer to demonstrate the feasibility of printing two-dimensional (2D) and complex 3D soft robots. These printed soft robots can be recycled and reprinted into new robots once their tasks are completed. Moreover, these robots show almost no difference in actuation capability compared to prior versions and have new functions. Successful applications include lifting, grasping, and moving objects, and these functions can be operated untethered wirelessly. In addition, the locomotion of the magnetic soft robot in a human stomach model shows the prospect of medical applications. Overall, these fully recyclable ferromagnetic fibers pave the way for printing and reprinting sustainable soft robots while also effectively reducing e-waste and robotics waste materials, which is important for resource conservation and environmental protection.
