  • Patent number: 11541642
    Abstract: With applications such as soft robotics being severely hindered by the lack of strong soft actuators, the invention provides a new soft-actuator material—Electrically Actuated Hydraulic Solid (EAHS) material—with a stress-density that outperforms any known electrically-actuatable material. One type of actuator is fabricated by making a closed cell that acts as highly paralyzed version of a standard paraffin actuator. Each cell exhibits microscopic expansion, which is summed to produce macroscopic motion. The closed cellular nature of the material allows the system to be cut and punctured and still operate. It can be produced in a lab or industrial scale, and can be formed using molding, 3D printing or cutting.
