TF8 Knee and Ankle Powered Prostheses
Please note: I currently have a manuscript in preparation, upon publication I will followup with far more information in this section.
My PhD has been the design, build, and control of a novel powered knee and ankle prosthesis. The technology is based on a series elastic actuator exploiting the biomimetic feature of series elasticity to extend the power delivery capacity of the motor as well as reduce overall energy consumption per stride. My process included feeding gait data through dynamic equations in a kinematically clamped manner, to search for the optimal configuration of motor, spring, gear ratio, and eventually also included searching for optimal linkage geometry with the objective of achieving minimal energy consumption for each stride of walking gait.
So far 7 people have used the actuator as an ankle and one has used it as both a knee and ankle.
