The Incredible Bebionic Mytoelectric Hand
“The Bebionic myoelectric prosthesis weighs about as much as a natural hand (0.88 – 1.32 lbs) and is controlled by small electrical signals in the body. These are generated by muscle contractions and can be measured with electrodes on the skin – the same way as an ECG in heart diagnostics. Two electrodes integrated into the prosthesis shaft detect the myoelectric signals and forward them to the control electronics. These signals are amplified and used to activate the five small electric motors (one for each finger) that move the fingers and thumb – the hand opens or closes itself. As a result, the strength of the muscle contraction controls the speed and the gripping force: a weak signal generates a slow movement; a strong signal generates a quick movement.” MORE
