Active Prosthetic Limbs

History of Prosthetic Limbs
 Prosthetic limbs have been around for 3000 years.
 Typically made of iron or wood.
 Served no real purpose.
 Insertion was crude.
 Until recently, prosthetics
utilized hooks.
Hook Hands
 Hooked prosthetics are
controlled manually.
 Incorporate a pulling
system.
 Very limited in function.
The First Commercial Active Prosthetic
 Touch Bionics I-Limb Ultra™
 Developed by David Gow of the Scottish National
Health Service and built by Touch Bionics™
 Major advance on previous hooked limbs.
 Became commercially available in 2007.
How It Works
 Sensors are imbedded in the arm.
 Impulses from the brain are read.
 A microprocessor controls each finger individually.
 Determines the amount of force necessary to grasp
an object.
