  Magnetic programming soft machines has great development prospects in the
fields of minimally invasive medicine, wearable device and soft robot. However,
unrepeatable magnetization and low modulus limits their applications. So far,
there are few techniques that can make magnetic soft robots have adjustable
functions, mechanical and electrical properties. This paper presented a
magnetic functional elastomer based on liquid metal-NdFeB-Silicone composite
materials. This magnetoelastomer uses the phase transition characteristics of
liquid-metal and magnetic guided rotation of micro ferromagnetic particles to
realize reprogrammable magnetization and modulus. The elastomer's fabrication
method was given and the basic programmable properties were tested. Some robot
prototypes have also been manufactured to show how to respond to different
mission requirements by programming magnetization and modulus. Our research
provides a new path for the design and large-scale manufacturing of magnetic
soft robot.
