The CYBERLEGs Beta-Prosthesis is an active transfemoral prosthesis that can provide the
full torque required for reproducing average level ground walking at both the knee and ankle …

A systematic review of the mechanical design of powered ankle–foot prostheses developed
from 2000 to 2019 was conducted through database and manual searches. A total of ten …

An emerging approach to design locomotion assistive devices deals with reproducing
desirable biological principles of human locomotion. In this paper, we present a bio-inspired …

Despite the increasing interest in using powered ankle-foot orthoses for assistive purposes,
their development and benchmarking still present core challenges. Powered orthoses have …

A Body and/or Caudal Fin (BCF) fish modulate its body stiffness by mechanisms consisting
of antagonistic muscles. The mechanisms can be considered as Redundant Planar …

The present manuscript describes the combined effect of using a parallel spring in
conjunction with a variable-stiffness actuator to reduce the torque and power requirements …

The use of active prostheses for lower limb replacement brings new challenges like power
optimization, energy efficiency and autonomy. The use of series and parallel elasticity is …

Joint mechanical impedance, which describes the instantaneous relationship between
kinematic perturbations and the resulting torque response, plays an important role in the …

The addition of active components to prostheses has the potential to extend the capabilities
and reduce metabolic energy consumption of users when compared to current prosthetic …

Inspired by the bionic characteristics of ankle and calf skeletal muscles, a novel ankle-foot
prosthesis (AFP) with variable stiffness mechanisms (VSMs) is proposed to assist transtibial …
