Designing a Variable-Stiffness Prosthetic Foot for Different Walking Terrains
Quick fact
Variable-stiffness prosthetic feet can change their stiffness in milliseconds, allowing amputees to walk on stairs, slopes, and uneven ground without changing the foot or making conscious adjustments.
Why this is interesting
Most prosthetic feet are stiff, yet they must work on stairs, slopes, and uneven trails. How do variable-stiffness feet adapt to each terrain?
