Medical plastics are bringing us a step closer to the bionic human. Electro-active polymeric materials, which behave like muscle fibre when an electrical current is applied, are expected to shape the future for artificial muscles and organs.
A good example is the Touch Bionics i-LIMB Hand. A first-to-market prosthetic device with five individually powered digits. This replacement hand, using high-strength plastics, looks and acts like a real human hand.
The i-LIMB Hand is controlled by a unique, highly intuitive control system that uses muscle signal (generated by the muscles in the remaining portion of the patient's limb) to open and close the hand's life-like fingers.
