A MONOLITHIC FLEXURAL-BASED PROSTHETIC FOOT FOR AMPUTEE

A new type of compliant prosthetic ankle-foot for amputee is developed. While current elastic energy storage and return feet have been widely commercialized, those designs still haven’t fully taken advantage of compliant mechanisms. The design in this research would help to reduce the fabrication and assembly cost but still preserves the flexibility which is the key characteristic to improve amputee gait. A shape and size optimization scheme via genetic algorithm and finite element method is undertaken to design the device. Model stiffness and levels of energy stored could be easily regulated with the proposed design methodology.
