Breakthrough in Brain-Computer Interfaces Restores Touch to Prosthetic Users

Researchers achieve stable and nuanced tactile sensations in prosthetic limbs through advanced brain stimulation techniques.

Scientists have developed brain-computer interfaces (BCIs) that enable prosthetic users to experience touch, including edges, shapes, and motion.
Electrodes implanted in the brain's sensory regions evoke precise, stable sensations, improving the usability of prosthetic limbs over years of testing.
Participants in the study could distinguish complex tactile inputs, such as letters and moving sensations, by interpreting signals from overlapping electrode stimulation patterns.
The research marks a significant step toward prosthetics that integrate natural-like touch, enhancing dexterity and confidence in everyday tasks.
Future advancements could extend this technology to other sensory restoration applications, such as post-mastectomy touch reconstruction.
