3D Upper-extremity ExoNET: Improved Passive Exoskeleton for Gravity Compensation and Motor Rehabilitation
Although passive designs may appear simple, their lightweight, low cost, and user-friendly configuration make them highly practical for use beyond controlled laboratory settings. Min imal setup, easy donning and doffing, and low maintenance allow both patients and clinicians to operate on them with …

Quantifying the Reliability of Performance Time and User Perceptions Obtained from Passive Exoskeleton Evaluations
… and reduce quality of life for those afflicted. Passive exoskeletons (EXOs) have emerged as a potential intervention to reduce worker exposures to WMSD risk factors. As EXO adoption is rising, EXO manufacturers are designing and producing new EXOs in accordance with growing demand. However, there …

Investigating the Relationship Between Objective and Subjective Measures of Physical Demand During Passive Exoskeleton Use
Passive exoskeletons hold promise in reducing the risk of work-related musculoskeletal disorders, however further research is essential before widespread adoption can occur. This study explores the feasibility of using subjective measures of physical demand in place of costly and less practical …

Simulation and Design of Two Tool Support Arm Exoskeletons with Gravity Compensation
We present and analyze two arm exoskeletons based on a pantograph linkage that allow for the support of 89~N (20~pounds) at the user's hand. Using a pantograph linkage allows for a constant force to be created at the hand in any orientation when a constant vertical force is supplied to the other …

Design and Evaluation of a Flexible Exoskeleton for Lifting
A flexible and passive exoskeleton is presented in this paper. The exoskeleton uses carbon fiber beams to provide an energetic return to its wearer and relieve their lower back muscles. The design of the exoskeleton and potential elastic mechanisms are described, and the results of biomechanical …

Design of a quasi-passive parallel leg exoskeleton to augment load carrying for walking
… suggest that it may be possible to build a leg exoskeleton to reduce the metabolic cost of walking while carrying a load. A quasi-passive, leg exoskeleton is presented that is designed to assist the human in carrying a 75 lb payload. The exoskeleton structure runs parallel to the legs, …

Development of Passive Lower Back Exoskeletons
The design of two passive back lift assist exoskeletons are presented in this thesis. The first exoskeleton uses carbon fiber as an energy storage medium while the second system utilizes a series system comprised of a gas spring and metal coil spring. The first exoskeleton was successfully tested …
