Human musculoskeletal systems are complex systems whose primary functions are to support and move the human body. Understanding the underlying fatigue mechanism of the musculoskeletal systems and devising its interface with external environment have significant indications in rehabilitation engineering and sports science. This disseratation first proposes a novel method for monoitriong the internal state, i.e. muscle fatigue, of the musculoskeletal system. The method tackles the challenge of limited measurable signals in monitoring biosystems by the fusion of data-driven and physics-based modeling methods. Desirables properties were achieved by the proposed fatigue metric including stronger monotonic trends and lower noise levels. The dissertation then proposes a softening interface of the human musculoskeletal system to improve its interaction with external environments, using structurally optimized constant force mechanisms. The softening interface was demonstrated in footwear designs, which significantly improved several critical performance metrics, including increased energy return and reduced peak force. The findings from this dissertation have significant indications in understanding the underlying fatigue mechanism and interface design of the musculoskeletal systems.
Haihua Ou received his B.S. and M.S. degree in University of Michigan – Shanghai Jiao Tong Unvieristy Joitn Institute from Shanghai Jiao Tong University in 2015 and 2018 respsectively. Now, he is a Ph.D. candidate student at the UM-SJTU Joint Institute, supervised by Prof. Shane Johnson. His current research focuses on the condition montiroing and interface design for the human musculoskeletal system.
