Nigel Ackland, who lost his arm in an accident six years ago, has been given a new lease of life by a hi-tech bionic hand which is so precise he can type again. Mr Ackland, 53, Royston, Cambs has been fitted with the Terminator-like carbon fibre mechanical hand which he can control with movements in his upper arm. The new Bebionic 3 Myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Mr Ackland's muscle twitches. The muscles twitches in his upper arm are detected by sensors that trigger one of 14 pre-programmed grips, mirroring human movements. The different grip patterns include a clenched fist, a pointed finger and a pincer and a lighter and heavier according to how the user tenses their upper arm. The robotic arm is so sensitive it means he can touch type on a computer keyboard, peel vegetables and even dress himself for the first time in six years.
