Summary
A team of researchers from China and Japan has developed an ultra-flexible brain implant electrode array that maintains 94% signal clarity after 18 months of implantation. The material boasts an electrical conductivity of 2,512 S/cm, enabling it to detect faint neural signals. Tested on rabbits over 550 days, the implant showed minimal inflammation and no significant immune response, suggesting strong biocompatibility for potential long-term brain-computer interface applications.

· 4 pulledIt has an electrical conductivity of 2,512 S/cm, letting it catch the faintest whispers of cellular thought.
For over 550 days, the freely moving animals broadcast crystal-clear neural activity.
Even after 18 months, the signal-to-noise ratio remained at 94 percent of its day-one clarity.
When the researchers examined the brain tissue using histological staining, they found almost no inflammation, no angry immune response.
