Students Create $20 Prosthetic Leg -- and It Works!
Students in the school's Biomedical Device Design and Evaluation program started the JaipurKnee Project, and challenged themselves to create a fully-functioning prosthetic leg that could be manufactured for a very low price. Clearly, they were successful, creating the above, fully-functioning appendage for just $20 in parts and production costs.
In order to improve upon the sorts of limbs currently used in developing countries, the team first studied high-end titanium knee joints, which cost anywhere from $10,000 to $100,000. It then explored standard materials found in cheap prosthetics around the globe, and, eventually, came up with the design for a self-lubricating knee joint made from an oil-filled nylon polymer, significantly cutting production costs.
The team's main goal is to produce and distribute some 100,000 joints over the next three years -- hopefully for even less than the current price of $20 a pop. [From: DVICE]
