A team of researchers from China and Japan has developed a ultra-flexible brain implant electrode array.
It overcomes a major hurdle in brain-computer interfaces (BCIs): the physical mismatch between stiff metal electrodes and soft brain tissue, which typically leads to chronic inflammation and signal degradation.
The development comes from Tsinghua University’s Shenzhen International Graduate School, the University of Tokyo and the Chinese Academy of Sciences’ Shenzhen-Hong Kong Institute of Brain Science.
Researchers tested the flexible brain implant in animal trials. Interestingly, it achieved long-term signal clarity and safe, stable functionality over an 18-month period.
