“Bionic” arm exoskeleton concept for rehabilitation and strength augmentation

http://titanarm.com/about

Titan Arm is an untethered, powered, upper body exoskeleton concept for use in rehabilitation and therapeutic applications, which can also augment strength.  It is under development and not yet ready to be brought to market, but is being designed by students at The University of Pennsylvania.  It straps directly to a user’s right arm to help lift heavy objects. Its inventors believe that it will be useful in aiding physical rehabilitation, both for people who have suffered upper body injuries and for those with pre-existing muscular-skeletal disorders.  The bionic limb can lift approximately 40 pounds of weight, and is predominantly made of aluminum and steel components, and powered by a DC battery.
