The National Science Foundation (NSF) Engineering program has awarded the University of Notre Dame a $357,240 project grant to develop innovative prosthetic limb technologies. This collaborative research project between Notre Dame and Brigham Young University aims to integrate optimal function and compliant mechanisms for improving the capabilities and accessibility of lower-limb powered prostheses.
The key objectives are to: 1) create a robust optimization framework to design parallel springs that can reduce motor torque requirements, enabling lighter, quieter, and more energy-efficient prosthetic components; and 2) develop a design framework for compliant mechanisms with optimal load-deflection profiles to reimagine existing rigid prosthetic parts. The research will result in an open-source compliant ankle design to complement the NSF-funded open-source leg. The project team will also engage with prosthetic users, manufacturers, and clinicians to incorporate feedback into new designs. Outreach activities include organizing a conference workshop, developing curriculum for a graduate course on wearable robotics, and hosting a summer STEM program for local middle school students. This 3-year award began on September 1, 2024.
