Biomimetic rigid-soft finger design for highly dexterous and adaptive robotic hands.
Science advances
Apr 23, 2025
In dexterous robotic hand design, achieving high mobility and adaptability comparable to human hands remains an ongoing challenge. Biomimetic designs mimicking the musculoskeletal structure have shown promise yet face difficulties in preserving key k...
Encoding mechanical intelligence using ultraprogrammable joints.
Science advances
Apr 23, 2025
Animal bodies act as physical controllers, with their finely tuned passive mechanical responses physically "encoding" complex movements and environmental interactions. This capability allows animals to perform challenging tasks with minimal muscular ...
Reversible kink instability drives ultrafast jumping in nematodes and soft robots.
Science robotics
Apr 23, 2025
Entomopathogenic nematodes (EPNs) exhibit a bending-elastic instability, or kink, before becoming airborne, a feature previously hypothesized but not substantiated to enhance jumping performance. Here, we provide the evidence that this kink is crucia...
Design and Implementation of a Soft-Rigid Hybrid Gripper with Bionic Ligaments and Joint Capsule.
Soft robotics
Apr 22, 2025
Dealing with grasping tasks in unstructured environments, existing soft grippers often exhibit a lack of static stability, while rigid-soft hybrid grippers display limited compliance due to the fixed connections at the joints. To address the challeng...
A wearable ankle-assisted robot for improving gait function and pattern in stroke patients.
Journal of neuroengineering and rehabilitation
Apr 22, 2025
BACKGROUND: Hemiplegic gait after a stroke can result in a decreased gait speed and asymmetrical gait pattern. Normal gait patterns and speed are typically the ultimate goals of gait function in stroke rehabilitation. The purpose of this study was to...
Deep learning-aided segmentation combined with finite element analysis reveals a more natural biomechanic of dinosaur fossil.
Scientific reports
Apr 22, 2025
Finite element analysis (FEA), a biomechanical simulation technique capable of providing direct mechanical visualization for CT-based digital models, has been extensively applied to fossil image datasets to address key evolutionary questions in paleo...
From marker to markerless: Validating DeepLabCut for 2D sagittal plane gait analysis in adults and newly walking toddlers.
Journal of biomechanics
Apr 18, 2025
The use of 3D marker-based motion analysis systems is considered the gold standard for tracking limb movements. However, these systems are expensive, limited to laboratory settings, and difficult to apply when studying paediatric populations. Therefo...
3D-printed programmable bistable mechanisms for customized wearable devices in tremor attenuation.
Journal of the mechanical behavior of biomedical materials
Apr 17, 2025
This research proposes a computational framework for designing a compliant bistable mechanism and fabricating it using 3D printing for customized medical applications. The proposed method reduces upper limb tremors, taking advantage of the nonlinear ...
Sticking the landing: Insect-inspired strategies for safely landing flapping-wing aerial microrobots.
Science robotics
Apr 16, 2025
For flying insects, the transition from flight to surface locomotion requires effective touchdown maneuvers that allow stable landings on a variety of surfaces. Landing behaviors of insects are diverse, with some using more controlled flight approach...
Neuro-Modulation Analysis Based on Muscle Synergy Graph Neural Network in Human Locomotion.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Apr 16, 2025
The coordination of muscles in human locomotion is commonly understood as the integration of motor modules known as muscle synergies. Recent research has delved into the adaptation of muscle synergies during the acquisition of new motor skills. Howev...
