Published in 2019 at "Nature"

DOI: 10.1038/s41586-019-1234-z

Abstract: Humans can feel, weigh and grasp diverse objects, and simultaneously infer their material properties while applying the right amount of force—a challenging set of tasks for a modern robot1. Mechanoreceptor networks that provide sensory feedback… read more here.

Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-92651-z

Abstract: Performing grasping tasks with prosthetic hands is often a slow and clumsy affair, requiring heavy reliance on visual feedback, greatly limiting the use of prosthetic hands in daily life activities. Automating the grasping tasks via… read more here.

Published in 2022 at "Journal of Neural Engineering"

DOI: 10.1088/1741-2552/ac9e1c

Abstract: Objective. Advanced myoelectric hands enable users to select from multiple functional grasps. Current methods for controlling these hands are unintuitive and require frequent recalibration. This case study assessed the performance of tasks involving grasp selection,… read more here.
