The Airy Arm is a device that provides users with the inability of moving their hand, this exact ability. It is 3D printed and utilizes cables that pull the fingers open and shut as the elbow bends and straightens. It allows for those with paralyzed hands to regain the use. It is developed by Elizabeth Jackson, a student of Jon Schull (e-NABLE founder). She is still working to improve the design but so far it works very well.
