Special Issue Information

Dear Colleagues,

Recently, wearable and flexible sensors have attracted tremendous research interest due to their promising applications in health-care monitoring, human–machine interfaces, electronic skin (e-skin), and soft robotics. Such sensors are prominent in the non-invasive measurement of various physiological signals and biomarkers in biological fluids. However, the following questions remain: what is the current state of the art, and what is the prospect of wearable sensors? In this Special Issue, we focus on the recent advancements, current challenges, and new opportunities of wearable and flexible physical and electrochemical sensors. We invite emerging investigators, experts, and researchers working on physical sensors (e.g., pressure, strain, temperature, humidity, ECG, etc.) and electrochemical biosensors to contribute their insightful ideas through commentaries, perspectives, future outlooks, and reviews. We highly encourage authors to submit developments focused on novel sensing materials, transduction principles, sensor design strategies, and their unique applications in the formats of either full-length articles or communications. Looking forward to the prospects and attention to the key challenges, we expect that wearable and flexible sensor devices will continue to spark a greater impact in disease diagnosis, e-skin, prosthetic body organs, and body sensor networks.

Lower-limb rehabilitation exoskeletons offer a transformative approach to enhancing recovery in patients with movement disorders affecting the lower extremities. This comprehensive systematic review delves into the literature on sensor technologies and the control strategies integrated into these exoskeletons, evaluating their capacity to address user needs and scrutinizing their structural designs regarding sensor distribution as well as control algorithms. The review examines various sensing modalities, including electromyography (EMG), force, displacement, and other innovative sensor types, employed in these devices to facilitate accurate and responsive motion control. Furthermore, the review explores the strengths and limitations of a diverse array of lower-limb rehabilitation-exoskeleton designs, highlighting areas of improvement and potential avenues for further development. In addition, the review investigates the latest control algorithms and analysis methods that have been utilized in conjunction with these sensor systems to optimize exoskeleton performance and ensure safe and effective user interactions. By building a deeper understanding of the diverse sensor technologies and monitoring systems, this review aims to contribute to the ongoing advancement of lower-limb rehabilitation exoskeletons, ultimately improving the quality of life for patients with mobility impairments.
