Abstract Occupational back exoskeletons and exosuits aim to reduce low injuries in the workplace. For these technologies be adopted, it is important that they provide biomechanical benefits wearer do not disrupt job performance. To address this challenge, here we developed a lightweight, soft, active exosuit can autonomously control virtual impedance apply differing assistance during lowering lifting. In usability tests, participants rated as easy learn use reported feeling confident while wearing it. an experiment involving hour-long order picking task demonstrated reduced peak median muscle activations by 18% 20%, respectively. Despite complexity of movements required, such walking, bending, navigating around obstacles lifting boxes from under rack, our controller impressive robustness with only 14 mistriggers out 9600 lifts (0.1%). The results research suggest technology has potential highly usable solution aid warehouse workers real-world settings.

Soft robotic exoskeletons have emerged as a transformative solution for rehabilitation and assistance, offering greater adaptability comfort than rigid designs. Myoelectric control, based on electromyography (EMG) signals, plays key role in enabling intuitive adaptive interaction between the user exoskeleton. This review analyzes recent advancements myoelectric control strategies, emphasizing their integration into soft exoskeletons. Unlike previous studies, this work highlights unique challenges posed by deformability compliance of structures, requiring novel approaches to motion intention estimation control. Key contributions include critically evaluating machine learning-based prediction, model-free methods, real-time validation strategies enhance outcomes. Additionally, we identify persistent such EMG signal variability, computational complexity, algorithms, which limit clinical implementation. By interpreting trends, need improved acquisition techniques, robust frameworks, enhanced learning optimize human-exoskeleton interaction. Beyond summarizing state art, provides an in-depth discussion how can advance ensuring more responsive personalized exoskeleton assistance. Future research should focus refining schemes tailored architectures, seamless protocols. is foundation developing intelligent that effectively support motor recovery assistive applications.

In highly mobile workplaces, wearable walking-assistant devices reduce muscle fatigue in workers’ lower extremities and increase energy efficiency. our study, we verify this following the development of an ultralight hip exoskeleton for industrial workers. Ten healthy male adults participated their activity, fatigue, expenditure were compared with without a device while walking on treadmill going up stairs. While assistive device, gastrocnemius decreased by 79.5%, oxygen uptake per minute 7.9% 7.4%, respectively. climbing stairs tibialis anterior 83.5%, average activity rectus femoris, semitendinosus, muscles significantly, 14% 12.9% minute, We confirm that helps wearer lower-limb use metabolic more efficiently. The results study are intended as basic data to expand exoskeletons at sites improve performance.

Heavy lifting operations frequently lead to upper limb muscle fatigue and injury. In order reduce fatigue, auxiliary force for limbs can be provided. This paper presents the development evaluation of a wearable exoskeleton (ULE) robot system. A flexible cable transmits torque is connected by bypassing shoulder. Based on K-nearest neighbors (KNN) algorithm integrated fuzzy PID control strategy, ULE identifies handling posture provides accurate active automatically. Overall, it has quality being light easy wear. unassisted mode, wearer’s minimally affect range movement. The KNN uses multi-dimensional motion information collected sensor, test accuracy 94.59%. Brachioradialis (BM), triceps brachii (TB), biceps (BB) electromyogram (EMG) signals were evaluated 5 kg, 10 15 kg weight conditions five subjects, respectively, during lifting, holding, squatting. Compared with without assistance assistance, average peak values EMG BM, TB, BB reduced 19–30% whole process, which verified that developed could provide practical under different load conditions.

Soft pneumatic actuators (SPAs) have applications in various domains due to their compliance, low cost, and lightweight characteristics. Herein, a geometric origami design for 3‐degree of freedom (DoF) SPAs is presented, which enables manufacturing using 3D printing at one go without any support structure. The proposed method uses general parameterization that works multiple types cylindrical patterns (Kresling, Miura, Yoshimura, Accordion). It shown 3‐DoF actuator capable bending extension can be constructed by superimposing two create separation chambers inside the module. In addition, parameters are chosen reduce strain during deformation maximize output forces actuator. manufactured, its motion force profiles experimentally characterized. designed bend from length operation vary between initial length.

Wearable strain sensors have transformed the real‐time monitoring of health conditions and human–machine interactions. However, recently developed wearable exhibit several limitations. For example, when a sensor is designed with high sensitivity to detect strain, it struggles accurately measuring deformation low‐stiffness materials like skin. Additionally, finding optimal balance between sensitivity, durability, hysteresis, range in design challenging. To address these challenges, Buckled, Ultrasoft, Crack‐based, Large EpiDermal (BUCKLED) developed. This integrates benefits soft structure engineering crack‐based sensing mechanisms ensure skin measurements. The BUCKLED exhibits significant improvements compliance (18 500 mm N −1 ), stretchability (100%), hysteresis (2%), durability (10 000 cycles 100% strain), force () owing its buckled shape, confirming ability subtle movements enhanced accuracy. sensor's allows measure objects, ensuring reliable performance. Furthermore, tunability demonstrating effectiveness applications such as respiratory monitoring, facial expression recognition, silent speech interfaces. Consequently, proposed versatile holds great potential for wide applications.
