A father who lost his arm in an accident six years ago has been given a new lease of life by a hitech bionic hand which is so precise he can type again. Nigel Ackland, 53, has been fitted with the Terminatorlike carbon fibre mechanical hand which he can control with movements in his upper arm. The new bebionic3 myoelectric hand, which is also made from aluminium and alloy knuckles, moves like a real human limb by responding to Nigel's muscle twitches. Incredibly, the robotic arm is so sensitive it means the fatherofone can touch type on a computer keyboard, peel vegetables, and even dress himself for the first time in six years.
