Using magnetic beads implanted into muscle tissue within the amputated residuum of animals, researchers have created a more precise way to control prosthetic limbs.
Researchers have developed a new method of restoring movement sensation for upper limb amputees. The researchers used small robots to vibrate muscles in order to 'turn on' movement sensations.
Researchers record the neural activity of monkeys as the plan to reach in order to design better neuroprosthetics.
A newly developed robotic thumb imprints how the hand is represented in the brain. Using the robotic thumb, researchers reported improvements in conducting dexterity tasks, such as building with blocks. Additionally, those who trained to use the additional thumb began to feel as though the digit was a part of their body.
A prosthetic arm that is attached to the bone and controlled by electrodes implanted in nerves and muscles can operate more precisely than conventional prosthetic limbs. Researchers improved the neuroprosthetic hand by integrating tactile sensory feedback, so the patient can "feel" items.
Researchers have developed a new electronic skin that can allow amputees to perceive touch sensations via their prosthesis. The technology, dubbed e-dermis, can recreate the sense of touch and pain by sensing stimuli and relaying impulses back to peripheral nerves.
Reconnecting muscle pairs during surgery following amputation provides patients more sensory feedback from the limb, researchers report.
Findings allow for the development of an autonomously updating brain-machine interface, which is able to improve on its own by learning about its subject without additional programming. The system could help develop new robotic prosthetics, which can perform more naturally.
Researchers have harnessed nature and biology to create a robotic finger that looks, feels and functions like a real finger.
University of Exeter researchers report people with prosthetic arms are not able to experience the 'size-weight' illusion as strongly as those without missing limbs.
