David Sengeh, a doctoral student at Massachusetts Institute of Technology (MIT), Cambridge, has won a $15,000 Lemelson-MIT National Collegiate Student Prize Competition (NCSPC) award. Sengeh is designing a socket that improves comfort and mobility for lower-limb prosthetic users. His approach, which uses quantitative and human data, merges magnetic resonance imaging (MRI) and 3D printing for customized prosthetic interfaces that reduce socket pressure. Prototypes have been tested by veterans and civilian patients, including amputees from the Boston Marathon bombings. Sengeh’s NCSPC award was given in the “Cure it!” category for technology-based inventions that can improve healthcare.
