You Probably Use Most Of These Things Every Day, and They Wouldn’t Exist Without NASA

Artificial Limbs

NASA made it possible for someone to walk again even after losing a leg. Coupled with innovations in shock absorption and robotics, NASA paved the way for prosthetic limbs to act like real arms and legs. At the outset, prosthesis were created using plaster and corn starch to create molds. However, the plaster molds were heavy and easy to break. To make matters worse, once the molds were broken, they were impossible to repair.

So instead of plaster, ET insulation was used. The ET worked a lot better with machines compared to plaster when producing prosthesis. Plus, the foam material that covered the ET was less expensive. The foam was also used to create molds for the fitting of artificial limbs. Because of this, it was less expensive to make artificial limbs. And since they were less expensive to make, patients were paying less in medical expenses.
