  • Publication number: 20240141929
    Abstract: This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.

  • Patent number: 10854450
    Abstract: The present disclosure describes patterned devices and methods for repairing substrate lattice damage in a patterned device. The patterned device includes a substrate, an alternating conductor and dielectric stack atop the substrate, a channel hole extending through the alternating conductor and dielectric stack to the substrate, and an epitaxial grown layer at a bottom of the channel hole and a top surface of the substrate. A part of the substrate in contact with the epitaxial grown layer has a dopant or doping concentration different from an adjacent part of the substrate. The method includes forming a channel hole in an insulating layer atop a substrate, forming an amorphous layer in a top side of the substrate below the channel hole, heating to crystallize the amorphous layer, and growing an epitaxial layer on the crystallized layer in the channel hole.

  • Patent number: 10722745
    Abstract: Systems and methods for a muscle signal-driven cycling system for persons with disability for rehabilitation are provided. A system comprises integrating both motor power and muscle power to facilitate rehabilitation cycling-based exercises. By using the intensity of real-time muscle activity signals as inputs, a motor applies either assistive or resistive force to rotate a gear at different speeds to facilitate or impede the cycling motion, and the electrical pulses from an electrical stimulation device can be provided to stimulate target muscles to generate muscle contraction to support the continuous cycling movement.
