Wireless Miniature Magnetic Phase-Change Soft Actuators.

ABSTRACT: Wireless miniature soft actuators are promising for various potential high-impact applications in medical, robotic grippers, and artificial muscles. However, these miniature soft actuators are currently constrained by a small output force and low work capacity. To address such challenges, a miniature magnetic phase-change soft composite actuator is reported. This soft actuator exhibits an expanding deformation and enables up to a 70 N output force and 175.2 J g^-1 work capacity under remote magnetic radio frequency heating, which are 10⁶ -10⁷ times that of traditional magnetic soft actuators. To demonstrate its capabilities, a wireless soft robotic device is first designed that can withstand 0.24 m s^-1 fluid flows in an artery phantom. By integrat
