i-LIMB Bionic Hand

Touted as a next-generation prosthetic device, the

i-LIMB Hand from Touch Bionics is a fully articulating bionic hand
that is commercially available right now.
Built with high-strength plastics, the hand is lightweight, strong, and
aesthetically pleasing.
Control signals are detected by two electrodes implanted under the skin,
then transmitted to a battery-powered processor which in turn
controls actuators and monitors gripping force.
Programmed grip patterns improve movements required in modern-day life
such as operating computer keyboards, ATM machines, and telephone dial
pads. Patients are also appreciating the life-like appearance of the
i-LIMB hand while at rest and in motion.
A patient
gallery and videos
