A "life changing" 3D printed hand has been created by scientists at the University of Bedfordshire for a boy born without fingers on his left hand.

The device, adapted from one created by a scientist in Africa, reads the signals in eight-year-old William's arm - which makes it fully controllable.

For the first time left-handed Will, who lives near Towcester, is able to hold a pen and draw a picture.

His mother Jo said: "He鈥檒l be able to do complex things like tie his laces, but also simple activities like holding a drink in one hand and an ice lolly in the other.

"I can鈥檛 thank these guys enough. What they're doing for William is life changing".
