ETH Zurich Engineers Represented Exo-Muscles For Hands 

ETH Zurich engineers have developed Myoshirt, a wearable hand exo-muscle that can compensate for conditions and injuries that affect the upper body. The first tests gave positive results.

The vest and cuff combination uses sensors to detect your intended movements and fires a motor that shortens the cable that runs along your muscles. Basically, you get extra tendon which provides extra strength and endurance.

A dozen volunteers could perform the exercises much longer than usual, with a 60 percent increase in endurance for a person with muscular dystrophy and a threefold increase in a person with a spinal cord injury.  According to scientists, even people without injuries worked out 30 percent longer.

But you are unlikely to be able to wear such a long time – the Myoshirt drive and a bulky external control unit weigh about 4 kg. The team is working on making the device smaller.
