A new Tornoto Star article presents a good overview of the latest developments in prosthetics including a $25,000 bionic leg made by Victhom Human Bionics that allows above-the-knee amputees to walk normally again. Another advanced prosthetic limb described is Otto-Bock's C-Leg which uses an intelligent microcontroller to adjust the leg's movements to compensate for rough terrain and even stairs. Also mentioned is Victhom's work on artificial exomuscles that could replace the electric motors now used in bionic limbs with power-saving active biomaterials.
