Unpowered Knee Exoskeleton during Stair Descent
2021 7th International Conference on Mechatronics and Robotics Engineering (ICMRE), 2021This study developed an unpowered knee exoskeleton which used the custom-built spiral spring to convert negative work to assist knee extension during stair descent. The optimization of the function angle and the stiffness of spiral spring were conducted to get the optimal parameters.

Reducing the Energy Cost of Human Running Using an Unpowered Exoskeleton
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2018 In this paper, we present a new perspective to design an unpowered exoskeleton for metabolic rate reduction in running. According to our studies on human biomechanics, it was observed that having a torsional spring that applies torque as a linear function of the difference between two hips angles ( -angle), compared with a local spring which applies ...

Regulating Metabolic Energy Among Joints During Human Walking Using a Multiarticular Unpowered Exoskeleton [PDF]
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2021 Researchers have found that the walking economy can be enhanced by recycling ankle metabolic energy using an unpowered ankle exoskeleton. However, how to regulate multiarticular energy to enhance the overall energy efficiency of humans during walking remains a challenging problem, as multiarticular passive assistance is more likely to interfere with ...

Development of an unpowered ankle exoskeleton for walking assist
Disability and Rehabilitation: Assistive Technology, 2018Aim: Assistive technologies traditionally rely on either powered actuation or passive structures to provide increased strength, support or the ability to perform specific functions. At one end of the spectrum are powered exoskeletons, which significantly increase a user's strength, but require powerful actuators, complex control systems and heavy power

Innovative Design for Portability of Unpowered Military Load Exoskeleton Robot
2018 IEEE International Conference on Information and Automation (ICIA), 2018For the poor portability of the unpowered military load exoskeleton robot, an innovative design strategy of exoskeleton portability based on TRIZ is proposed. An innovative design process model of exoskeleton based on conflict solving theory is established, and its convenient and portable function has been implemented.

Kinematic Analysis and Simulation of a Novel Unpowered Exoskeleton with Parallel Topology
2019 IEEE 9th Annual International Conference on CYBER Technology in Automation, Control, and Intelligent Systems (CYBER), 2019this paper proposes a novel unpowered structure to enhance the load-carrying ability for a person. Firstly, the kinematics model is built by the close-loop method; the analysis of the position problems of the exoskeleton with double closed kinematic chains are gotten. Then, the relation between each angel are depicted by MATLAB.
