Retractable Prosthesis for Transfemoral Amputees Using Series Elastic Actuators and Force Control
This addresses mobility challenges for transfemoral amputees with a novel design, though it appears incremental as it builds on existing actuator technology.
The researchers developed a cost-effective transfemoral prosthesis using series elastic actuators for accurate force control, achieving improved functionality with low impedance and a large dynamic range.
We present a highly functional and cost-effective prosthesis for transfemoral amputees that uses series elastic actuators. These actuators allow for accurate force control, low impedance and large dynamic range. The design involves one active joint at the knee and a passive joint at the ankle. Additionally, the socket was designed using mirroring of compliances to ensure maximum comfort.
