  • Low-voltage soft actuator capable of linear motion in air
    Patent number: 12245512
    Abstract: The present invention relates to an actuator including: a first ionic polymer layer disposed on underside of a first electrode layer; a second ionic polymer layer disposed on top of a second electrode layer; and a porous conducting interlayer disposed between the first ionic polymer layer and the second ionic polymer layer.
    Type: Grant
    Filed: November 22, 2021
    Date of Patent: March 4, 2025
    Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATION
    Inventors: Moon Jeong Park, Hyeon Seong Ham, Dipankar Barpuazary
  • SENSOR-INTEGRATED ACTUATOR, AND HAPTIC FEEDBACK SYSTEM USING SAME
    Publication number: 20240321067
    Abstract: Haptic interaction system remotely operated by human hand through real-time haptic feedback, and a sensor-integrated iEAP actuator included in the system are provided, in which when a gripper including the sensor-integrated iEAP actuator that operates in conjunction with the user's finger movements comes into contact with an object, changes in signal of the sensor included in the sensor-integrated iEAP actuator are transmitted to the user as haptic feedback in real time, thereby enabling stable gripping without a visual sensor.
