At the forefront of this technology is the myoelectric prosthetic.

Myoelectric prosthetics have a number of advantages over body-powered prosthetics.

Since it uses a battery and electronic motors to function, the myoelectric artificial limb does not require any unwieldy straps or harnesses to function.

Instead, it is custom made to fit and attach to the remaining limb (whether above the elbow or below) with maximum suspension using suction technology.

Modern prostheses enable replacements of limbs lost to injury or disease.Their heavy weight is primarily due to the fact that the myoelectric artificial limb contains a battery and motor inside, and unlike the body-powered prosthetic, it does not use any harnesses to counter-balance the weight across the body.This is an admitted trade-off for a more natural appearance.As well, though the user experiences direct control and feedback through its mechanical operation, the process can be fatiguing.Externally-powered artificial limbs are an attempt to solve this physical exertion through using a battery and an electronic system to control movement.The most advanced versions of these prosthetics are incredibly natural and on par with purely cosmetic limbs.The primary disadvantages of this kind of prosthetic are currently their weight and cost.While it is currently more expensive than other kinds of prosthetics, it also offers the best quality in regard to both cosmetics and functionality.Like the problem of weight, it is estimated that the cost will eventually diminish as the technology becomes cheaper to reproduce.Sleek, elegant and cutting-edge in both design and technology, the bebionic range pushes the boundaries of multi-articulating myoelectric hands.14 selectable grip patterns and hand positions enable you to perform a huge number of everyday activities with ease. The Axon Hook is a high-performance, robust terminal device and compliments the Michelangelo Hand perfectly.
