Leveraging LSTM, tactile sensors, and haptic feedback to augment prosthetic control via grasp type prediction and grasp type feedback [PDF]

Scientific Reports
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.

Early Predictability of Grasping Movements by Neurofunctional Representations: A Feasibility Study

Applied Sciences, 2023
Human grasping is a relatively fast process and control signals for upper limb prosthetics cannot be generated and processed in a sufficiently timely manner. The aim of this study was to examine whether discriminating between different grasping movements

Control Methods for Transradial Prostheses Based on Remnant Muscle Activity and Its Relationship with Proprioceptive Feedback

Sensors, 2020
The loss of a hand can significantly affect one’s work and social life. For many patients, an artificial limb can improve their mobility and ability to manage everyday activities, as well as provide the means to remain independent. This paper provides an
