prosthetics

Researchers and clinicians make small muscle grafts into the arms of amputees to amplify the signals from their peripheral nerves, which then direct the movement of a robotic hand.

A 3-D printed prosthetic hand moves by reading the signals in forearm muscles.

See amputee Amanda Kitts manipulate objects using nervous impulses to control an early prototype of her advanced artificial limb.

Scientists recreate proprioception for people with artificial arms using a perceptual illusion.

The device could one day help enable prosthetics deliver richer touch information to users.

Artificial photoreceptors made of nanowires help restore blind animals’ sensitivity to light.

Scientists are analyzing how factors such as the length and stiffness of artificial limbs affect performance in athletes with amputations.

Alena Grabowski, a University of Colorado Boulder researcher, discusses her motivations for studying the interface between biology and mechanics in prosthetic devices.

New surgical techniques may help amputees feel more enmeshed with their artificial limbs.

Researchers create an artificial nerve that could be the forerunner of neural prosthetics.

A quadriplegic 28-year-old man senses touch via stimulation of electrodes implanted in his somatosensory cortex.

A new flexible sensor can detect touch and generate electrical pulses that signal intensity of pressure to mouse neurons in vitro.

Until recently, auditory brainstem implants have been restricted to patients with tumors on their auditory nerves.

Researchers network the brains of three monkeys to create a “living computer” that can steer an image of a robotic arm toward a target.

A new light-sensitive nanotube-based film could pave the way to more flexible and durable retinal implants.

Linking the human nervous system to computers is providing unprecedented control of artificial limbs and restoring lost sensory function.

Artificial limbs and their wearers achieve more sensitive communication thanks to engineering advances.

Melvin Glimcher, inventor of the prosthetic “Boston Arm,” which moves in response to electrical signals from the wearer, has passed away at age 88.

The agency OKs the first prosthetic arm controlled by neural signals from the user’s muscles.
