Biologically inspired design and development of a variable stiffness powered ankle-foot prosthesis (2019)
Journal Article
Dobson, A., Wei, G., & Ren, L. (2019). Biologically inspired design and development of a variable stiffness powered ankle-foot prosthesis. Journal of Mechanisms and Robotics, 11(4), https://doi.org/10.1115/1.4043603

Recent advancements in powered lower limb prostheses have appeased several difficulties faced by lower limb amputees by using a Series-Elastic Actuator (SEA) to provide powered sagittal plane flexion. Unfortunately, these devices are currently unable... Read More about Biologically inspired design and development of a variable stiffness powered ankle-foot prosthesis.
