Chinese scientists create record-smashing brain implant electrode array thinner than hair

A China-led team of researchers has developed a powerful brain implant electrode array that is as soft as brain tissue, thinner than a strand of hair and more durable than anything before it.
In animal trials, a new flexible brain implant recorded neural activity with unprecedented long-term clarity and remained safely functional inside the body for 18 months.
The breakthrough addressed a major hurdle that had long held back brain-computer interfaces.
Invasive interfaces deliver the clearest and...
