Wrist Assistive Device

Visiting Researcher Project; Hiroshima University

Project Description

Developed in the BSYS group, Kurita lab, Hiroshima University (広島大学); Summer 2016.

Co-designed with Swagata Das. Advisor = Prof. Yuichi Kurita.


Assisting motions in the human body reduces muscular activation, and eventually, fatigue. Two students developed an assistive glove for a human wrist that was equipped with a set of pneumatic actuators. The actuators act like artificial muscles for supporting a user’s various motions, which include flexion, extension, and, pronation of the wrist. A series of experiments were carried out in order to verify the effectiveness and efficiency of the glove design by measuring EMG (electromyography) signals of relevant muscles, and positive results obtained. Accepted for presentation and live demo at AsiaHaptics 2016 (November in Chiba, Japan).

Project Details
  • Enables 3 types of motion: flexion, extension, & rotation.

  • Activated via onboard stretch sensors, ie triggered by initiation of user's own movement.
