Summary: Body weight support overground walking training is widely used in gait rehabilitation, but existing systems are not suitable for the clinical environment due to their large workspace, complex structure, and high installation cost. In this study, a self-paced treadmill system with optimized body weight support was proposed, which showed cost/space effectiveness and more accurate measurement performance compared to motion sensor.

Summary: This study aims to investigate the effects of serial BLTT on spatial aspects of backward and forward walking in chronic post-stroke individuals with residual walking impairment. The results show an overall improvement in BLTT and overground walking speeds, bilateral step lengths, and single-support center of pressure distances over six training sessions. Additionally, there were weak positive associations between changes in BLTT speed, BLTT paretic step length, and overground forward walking speed.

Summary: Robotic rehabilitation is an effective solution for recovery from neuromuscular diseases and assists physical therapists in high-intensity and repetitive training. The main challenge in utilizing rehabilitation robots is the high cost of technology and maintenance. To address this issue, a low-cost and highly transparent robotic therapy orthosis, powered by a single pneumatic artificial muscle, is introduced. A novel control approach combining admittance control and compliant controls enables smooth movement and a new assist-active modality named Patient Activated Assistance (PAAM) improves patient engagement. The performance of the orthosis is verified using electromyogram measurements. This study suggests that the proposed low-cost robotic orthosis could be a valuable solution for robotic rehabilitation, particularly in low-middle-income countries.

Summary: Lithium-sulfur (Li-S) batteries have advantages in terms of high theoretical specific capacity, rich sulfur resources, low production cost, and environmental friendliness, making them promising rechargeable energy storage devices. However, the shuttle effect of polysulfide hampers their commercialization by causing passivation of the anode, decreased capacity and efficiency, and reduced cycle stability. To address this issue, modifying the separator surface and introducing functional modified layers are effective strategies. Additionally, catalyzing the polysulfide conversion reaction can also hinder the migration of polysulfides. This review provides an overview of separator modification, functionalization, and catalysis in Li-S batteries, and prospects the future research trends in the field.

Summary: In this work, a ZnO1-x/Ti3C2 composite with rich oxygen vacancies was prepared by a hydrothermal process and subsequent annealing in a hydrogen atmosphere, showing high responses to low concentrations of NO2 at room temperature. The excellent sensing properties of the ZnO1-x/Ti3C2 composite are attributed to the presence of abundant oxygen vacancies and the formation of a ZnO1-x/Ti3C2 Schottky barrier. The composite also demonstrates high selectivity to NO2 compared to other gases. This study provides new insights into enhancing the room-temperature gas sensitivity of MOS-containing composites by constructing oxygen vacancies and heterojunctions.

Summary: The selection of an actuation system for assistive robotic exoskeletons involves careful consideration of various design factors, including lightweight and power-efficient requirements. This paper explores the exploitation of actuation redundancy in a study comparing the design optimization of rigid and elastic systems. A multi-factor optimization technique is developed for a redundant elastic actuation system, evaluating different actuator choices to determine the optimal motor and transmission system combination. The results show that the optimal redundant actuation system significantly reduces power requirements, with the variable parallel elastic actuators (V-PEA) outperforming variable series elastic actuators (V-SEA) in the case study.

Summary: Currently, there is a lack of objective and precise evaluation methods for assessing hand function in stroke patients. To address this, we proposed a new assessment method that utilizes hand movement data collected from the Leap motion device. By analyzing and ranking the selected sensitive metrics, we were able to determine the most sensitive kinematic metrics to distinguish differences in hand function between normal individuals and stroke patients. The experimental results showed that the proposed method was effective, scientifically objective, and could assist with the evaluation of hand function in stroke-induced hemiplegia.
