Krista Donaldson: The $80 prosthetic knee that's changing lives
Prosthetic limbs are expensive and complex, and they must be fit to each individual -- yet having a replacement for a lost limb can mean the difference between working and not, having a social life and not. So, Krista Donaldson and her team at the nonprofit design firm, D-Rev, are attacking the problem on several fronts, from re-engineering the moving parts, to exploring way-new materials that replace expensive titanium, to forming deep local partnerships for distribution and maintenance around the world.
We've made incredible advances in technology in recent years, but too often it seems only certain fortunate people can benefit. Engineer Krista Donaldson introduces the ReMotion knee, a prosthetic device for above-knee amputees, many of whom earn less than $4 a day. The design contains best-in-class technology and yet is far cheaper than other prosthetics on the market.
