Prosthesis allows amputees to walk in heels

We've seen some interesting prostheses over the years, from 3D-printed legs to devices for kids with superhero aesthetics. A project from researchers at the Johns Hopkins University is a little different, providing a prosthesis to help women with lower limb amputations to walk in high heels. It's an effort that could have a huge positive impact on peoples' lives, from female veterans to the fashion conscious.Read More

Lego-compatible prosthetic arm lets kids' imaginations run wild

For Colombian designer Carlos Torres, how to best tackle the low self-esteem and social isolation felt by child amputees is about more than finding the the most advanced prosthetic money can buy. His IKO Creative Prosthetic System is aimed at unleashing the creative expression of those with missing limbs, and to do so he's enlisting every child's favorite building blocks. The result is an artificial limb where kids can swap robotic grippers for laser-shooting spaceships whenever the opportunity arises.Read More

Shape-memory wire simulates muscle in high-precision artificial hand

Whether they're on robots or amputees, artificial hands tend to be rather complex mechanisms, incorporating numerous motor-driven cables. Engineers from Germany's Saarland University, however, have taken a different approach with their hand. It moves its fingers via shape-memory nickel-titanium alloy wires, bundled together to perform intricate tasks by working like natural muscle fibers.Read More

Prosthetic arm takes alternate route to mind control

Researchers from the Medical University of Vienna have developed a technique that allows amputees to control a robotic prosthesis with their mind when there's no neural connection left to exploit between the brain and the part of the hand that remains. Called "bionic reconstruction," the procedure was applied to three patients who were able to successfully use the prosthesis to undertake routine activities, thereby improving their quality of life.Read More
