Artificial sensory nerve made of flexible organic electronics

Artificial sensory nerve made of flexible organic electronics
Stanford and Seoul National University researchers have developed an artificial sensory nerve system that can activate the twitch reflex in a cockroach and identify letters in the Braille alphabet. The work, reported in Science, is a step toward creating artificial skin for prosthetic limbs, to restore sensation to amputees and, perhaps, one day give robots some type of reflex capability.

Computer models improve function of prosthetic devices

Computer models improve function of prosthetic devices
Researchers have developed technology for decoding neuromuscular signals to control powered, prosthetic wrists and hands. The work relies on computer models that closely mimic the behavior of the natural structures in the forearm, wrist and hand. The technology could also be used to develop new computer interface devices for applications such as gaming and computer-aided design (CAD).

Prosthetic hand offers latest capabilities at lower price

Prosthetic hand offers latest capabilities at lower price
Engineers from the Italian Institute of Technology and Italy’s National Institute for Insurance against Accidents at Work (INAIL) have unveiled a prosthetic hand that they claim “gives the patient approximately 90% functionality of a natural hand.” The Hannes was designed to lower the price of advanced powered prostheses, while having a long battery life, a strong grip, and manipulation of individual fingers.

Successful implementation of prosthetic memory in humans

Successful implementation of prosthetic memory in humans
Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person’s own memory patterns to facilitate the brain’s ability to encode and recall memory. In the pilot study, published in the Journal of Neural Engineering, participants’ short-term memory performance showed a 35 to 37% improvement over baseline measurements.

Kinesthetic feedback improves control of prosthetic devices

Kinesthetic feedback improves control of prosthetic devices
Researchers at Cleveland Clinic have introduced a system that recreates so-called kinesthetic perception and significantly improves the dexterity of individuals using hand prostheses. Their technology involves vibrators that stimulate the muscles that are used to control the movement of prostheses. As the fingers of the device are opened and closed, vibrations are induced, the nature of which reveals to the user where their hand is.

Brain perceives prosthetic devices as real hands

Brain perceives prosthetic devices as real hands
The human brain can take advantage of brain resources originally devoted to the hand to represent a prosthetic limb, a new UCL-led study concludes. Among people with only one hand, the brain area that enables us to recognise hands can also recognise a prosthetic hand, particularly among those who use a prosthesis regularly, according to the Brain paper. The study provides the first account of how artificial limbs are represented in the brains of amputees.

Adaptive powered knee prosthesis assists amputees

Adaptive powered knee prosthesis assists amputees
North Carolina State University research into wearable robotics shows how amputees wearing these devices adapted when presented with a real-world challenge: carrying a weighted backpack. The results could assist device manufacturers and clinicians expand the utility of these important devices, and could help researchers develop smarter controllers that adapt to real-world demands.

Brain rewires itself to adjust to advanced prostheses

Brain rewires itself to adjust to advanced prostheses
  EPFL scientists from the Center for Neuroprosthetics have used functional MRI to show how the brain re-maps motor and sensory pathways following targeted motor and sensory reinnervation (TMSR), a neuroprosthetic approach where residual limb nerves are rerouted towards intact muscles and skin regions to control a robotic limb.

Flexible skin for prosthetics can sense shear force

Flexible skin for prosthetics can sense shear force
If a robot is sent to disable a roadside bomb — or delicately handle an egg while cooking you an omelet — it needs to be able to sense when objects are slipping out of its grasp. Yet to date it’s been difficult or impossible for most robotic and prosthetic hands to accurately sense the vibrations and shear forces that occur, for example, when a finger is sliding along a tabletop or when an object begins to fall.

Investigating the competitive neuroprosthetics market

Investigating the competitive neuroprosthetics market
The market for cochlear implants, retinal implants and neuroprosthetic limbs is expected to reach $18bn by 2028. The new IDTechEx Research report, Neuroprosthetics 2018-2028: Technologies, Forecasts, Players, covers this competitive landscape. An analysis of patent timelines and major developments alongside the most recent technologies is provided for major players in each respective category. These timelines are particularly useful in answering a number of interesting questions for this field.
