Having identified a new, simpler way to study neural activity, researchers believe they are on track to creating a compact, low power and potentially wireless brain sensor that could make thought-controlled prosthetic limbs ubiquitous.
Sensory signals transmitted from a prosthetic leg to the nervous system helps amputees perceive their prosthetic limb as part of their body. The new neurofeedback helps them perceive the new limb as significantly lighter.
DARPA's HAPTIX program seeks to provide amputees with natural touch sensations.
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.
Researchers are one step closer to developing a prosthetic arm that can recreate a sense of touch through a direct brain interface.
