Researchers in the US have developed a new way to connect tiny electronic circuits to the human brain. John Rogers of the University of Illinois at Urbana-Champaign and colleagues have developed a high-quality biocompatible interface from silk substrates containing electronic components that can “wrap” itself around biological tissue. The system allows electrical activity of living tissue to be measured with unprecedented precision, without damaging the tissue in any way.
