Shoulder motion is essential for daily activities, yet accurate quantification outside laboratory settings remains challenging. Existing wearable systems either accumulate drift over extended recordings or rely on elaborate calibration protocols that...

Combining wearable inertial measurement units with soft strain sensors enables stable, long-duration monitoring of shoulder motion. With only brief calibration, this hybrid approach corrects drift in inertial sensing, enabling reliable tracking of complex...

Stroke-induced abnormal upper extremity (UE) joint coupling limits independent joint control and impairs functional arm use. While previous studies have predominantly evaluated UE joint coupling within the plane of motion (in-plane) and its effect on...

Objective: Gait-assistive technology has the potential to benefit millions, but adoption is limited by challenges in tuning assistance to simultaneously provide biomechanical benefits and satisfy patient and clinician preference. In this study, we...

Actuators for wearable robots are difficult to design due to the competing requirements of minimizing weight and form factor while achieving desired performance requirements. Current solutions often rely on a “one-size-fits-all” approach utilizing...

Background: Assistive technology offers an important means of compensating for lost upper extremity function in adults with progressive neuromuscular diseases (NMD), enabling participation in daily activities, supporting independence, and promoting...

Accurately estimating kinetic metrics, such as braking and propulsion forces, in real-world running environments enhances our understanding of performance, fatigue, and injury. Wearable inertial measurement units (IMUs) offer a potential solution to...

Introducing engineering design early in science education can be a path toward inspiring young students to develop feelings of belonging in STEM. For some educators, robotics kits are seen as a classroom-ready platform for teaching engineering design...

Amyotrophic lateral sclerosis is a progressive neurodegenerative disease affecting upper and lower motor neurons that control voluntary muscles. With no known cure, clinical care is focused on symptom management to maximize function and quality of life...

Portable wearable robots offer promise for assisting people with upper limb disabilities. However, movement variability between individuals and trade-offs between supportiveness and transparency complicate robot control during real-world tasks. We address...

Nearly all soft wearable robots rely on textiles to distribute actuation forces to the human body; however, the mechanical hysteresis of these materials significantly complicates device control. If not properly accounted for, this history-dependent...

Static aerodynamic surfaces are inherently limited in their ability to adapt to dynamic velocity profiles or environmental changes, restricting their performance under variable operating conditions. This challenge is particularly pronounced in high-speed...
