Unpowered Knee Exoskeleton Reduces Quadriceps Activity during Cycling
Engineering, 2018 Cycling is an eco-friendly method of transport and recreation. With the intent of reducing the energy cost of cycling without providing an additional energy source, we have proposed the use of a torsion spring for knee-extension support.

Reducing the energy cost of human walking using an unpowered exoskeleton [PDF]
Nature, 2015 Walking is the most commonplace of activities, yet we know remarkably little about it and no robot has yet reproduced the grace and poise of a human walk. Steven Collins et al. now show that the attachment of a simple mechanical exoskeleton to the foot and ankle results in a 7 reduction of the metabolic energy expended in walking.

Reducing the metabolic energy of walking and running using an unpowered hip exoskeleton [PDF]
Journal of NeuroEngineering and Rehabilitation, 2021 Background Walking and running are the most common means of locomotion in human daily life. People have made advances in developing separate exoskeletons to reduce the metabolic rate of walking or running. However, the combined requirements of overcoming

Modeling and Simulation of an Unpowered Lower Extremity Exoskeleton Based on Gait Energy [PDF]
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Aiming at the problem of how to store/release gait energy with high efficiency for the conventional unpowered lower extremity exoskeletons, an unpowered lower‐limb exoskeleton is proposed. In the current study, the human motion model is established, and the change rule and recovery/utilization mechanism of gait energy are illustrated. The stiffness and

A Review of Wearable Back-Support Exoskeletons for Preventing Work-Related Musculoskeletal Disorders [PDF]
BiomimeticsLong-term manual material handling (MMH) work leads to the trend of the younger onset of work-related musculoskeletal disorders (WMSDs), with low back pain (LBP) being the most common, which causes great trouble for both society and patients.
