  • Electromagnetic soft actuators
    Patent number: 11448103
    Abstract: In one embodiment, an electromagnetic soft actuator includes a first soft outer member comprising a soft internal electrically conductive coil, a second soft outer member comprising a soft internal electrically conductive coil, and a soft inner shaft on which the first and second soft outer members are mounted, the first and second soft outer members being linearly displaceable along a length of the soft inner shaft, the soft inner shaft comprising a permanent magnet, wherein the first and second outer members linearly move under an electromagnetic force relative to the soft inner shaft and each other when an electric current is applied to the soft internal electrically conductive coils.
