Computer-controlled artificial legs have aided in improving amputees' freedom of movement by mimicking the natural motion of their missing limbs. Now, a new robotic ankle promises to make this motion even more precise by dynamically adjusting to the terrain underfoot.

A low-cost, programmable, 3D-printed prosthetic hand may soon change the lives of amputees in Ecuador. The hand costs just US$270 to manufacture, making it a small fraction of the cost of a typical prosthetic of this type.

While there seems to be new applications popping up everyday, no industry is poised to benefit from this 3D printing in quite the way medicine is. The latest groundbreaking treatment involves an Indian cancer patient who has had his upper jaw replaced with the help of 3D printing.

Touch Bionics has unveiled the latest enhancements to its i-limb Ultra Revolution at OTWorld 2014 International Congress. Users can now set and assign different grips for different objects and configure the prosthetic hand via Android apps.
-
DARPA's recently announced Hand Proprioception and Touch Interfaces (HAPTIX) program aims to develop more lifelike prosthetic limbs that bring some sense of being part of the the wearer’s body, not something just strapped on.
-
Researchers at Michigan Technological University are developing a microprocessor-controlled prosthetic leg with an ankle that lets the foot tilt up and down and roll from side to side. It is said to allow for a more stable walking gait.
-
DARPA has instituted programs to improve neural interfaces and allow amputees to have better control of advanced prostheses in the near term.
-
Touch Bionic’s i-limb ultra revolution robotic artificial hand is linked to a smartphone app for greater control of the hand.
