Knee exoskeletons have gained increasing attention for gait training and intervention. The effectiveness of conventional rigid is degraded by bulkiness, high inertia, joint misalignment. soft configurations relax the constraints on knee joint, thus circumvent misalignment issue, reduce system size weight. However, sacrifice load sharing capability from support, also mechanical stop constraining working range to avoid unsafe hyperextension. This article presents a novel rigid-soft hybrid...
In this paper, we aim to investigate the effect of proprioceptive neuromuscular facilitation (PNF)-based rehabilitation for ankle plantar flexors spasticity by using a Robotic Ankle-foot Rehabilitation System (RARS). A modified robot-assisted system was proposed, and seven poststroke patients with hemiplegic spastic ankles participated in 3-month robotic PNF training. Their impaired sides were used as experimental group, while their unimpaired control group. intervention group started from...
In this paper, we present a powered bionic knee exoskeleton aiming at physical assistance and rehabilitation. The mechanical structure of the is based on anthropomorphic design, tibia rolling or sliding femur during joint movements. addition, proxy-based mode controller used to improve safety wearable device. Preliminary experimental results trajectory tracking dynamic response verify feasibility proposed exoskeleton.
Robotic platform-based ankle–foot rehabilitation systems have been proved effective in treating joint spasticity and/or contracture of stroke survivors. However, simple force or velocity limiters are not adequate, since they cannot explicitly guarantee slow and overdamped motions without overshoot. In this paper, we propose a proxy-based sliding mode control (PSMC)-based approach, to avoid unsafe behaviors robotic system. The proposed method has three advantages: (1) deteriorating tracking...
Swimming stroke classification and underwater motion analysis are important in swimming training. In this paper, we propose an IMU-based wearable sensing system for recognizing strokes analysis, focusing on lower-limb movements. The measures 12 channels of posture signals from the shank, thigh, foot two legs. Three competitive swimmers were recruited experiments. With a stroke-dependent quadratic discriminant classifier selected time-domain features, proposed can achieve satisfactory...
In this paper, we present the preliminary evaluation of gait assistance during treadmill walking with a powered bionic knee exoskeleton (BioKEX) which is intended for rehabilitation patients joint movement disorder. The BioKEX unilateral and light-weight wearable exoskeleton. anthropomorphic design that tibia rolls on femur flexion/extention implemented by gear meshing mechanisms. We applied finite-state machine based impedance control approach control. desired torque locomotion mode...
Wearable electrical textiles are of great value for future personalized healthcare applications. Herein, we report a 3-D meshed textile pressure sensor, using facile dip coating strategy, that combing the sensitive 2-D Ti3C2Tx MXene nanolayer with woven fibers. Based on cross-connected conductive network, sensor achieves simultaneously high sensitivity up to 81.9 kPa−1 and fast response time 30 ms in wide detection range (0–19 kPa) as well prominent durability more than 5000 cycles....
High mechanical loads generated during walking may accelerate the wear of knee joint. General exoskeletons mainly reduce joint load by applying pure torque assistance to force required extensor muscles. This study aims further early and middle stance phases through a gait intervention strategy that combines vertical assistance. Comprehensive experiments were conducted verify in reducing load. The results demonstrated significantly reduced maximum mean phases. Our studies indicated have...
This paper presents an underwater lower-extremity soft exoskeleton which could provide assistance to swimming motions. With this motivation, we designed called Powered Swimsuit assist the wearer in breaststroke with fins. The actuation system was embedded inside of a portable waterproof cabin fabricated on back swimsuit. assistive force applied bottom fins via cables. During propelling period stroke cycle, cables pulled ankle joints plantar flexion. Three competitive swimmers participated...
Real-time human intent recognition is important for controlling low-limb wearable robots. In this paper, to achieve continuous and precise results on different terrains, we propose a real-time training method six locomotion modes including standing, level ground walking, ramp ascending, descending, stair ascending descending. A system designed the purpose with an embedded BPNN-based algorithm. powered orthosis integrated two inertial measurement units used as experimental setup evaluate...
Locomotion intent recognition is essential for human-robot interaction to realize assistance control. In this study, we proposed a real-time locomotion method running on the exoskeleton control hardware, which can recognize current mode and detect transitions in advance. Signals from two inertial measurement units installed (one thigh part, other shank part) are used human intents, include three modes (level walking (LW), stair ascending (SA) descending (SD)) four (LW → SA, SA LW, LW SD LW)...
Proper steel model for reinforcing bar incorporating inelastic buckling is essential precise seismic analysis of reinforced concrete structures. Steel without considering will obviously overestimate the corresponding stress if rebar under cyclic loading and emerges in compressive loading.

A parameter...
Endometriosis (EM) is a common chronic inflammatory disease in women. Sampson’s retrograde menstruation theory the most widely accepted of EM pathogenesis. The periodic bleeding ectopic lesions an important pathological feature this disease, and occurrence progression are closely associated with iron overload caused by lesions. However, animal models that simulate menstrual-blood reflux hemorrhage from lacking. In study, we performed intraperitoneal injection endometrial fragments blood to...
