Hannes

(project ref. number: PR19-PAS-P1)

 

The Hannes hand prosthesis, available from 2019, is a device capable of reproducing approximately 90% of the functionality of a natural hand.

It allows the user to grasp objects, adapting to the shape and external resistances, making gestures more fluid.

All of this, compared to other similar devices, with a cost of 30% less and higher performance, in terms of versatility, aesthetics and battery life that can last up to a whole day. The integration of the prosthesis in a complete upper limb prosthetic system will soon be available.
