Ultrathin electrode spun from a single carbon fiber can record neurons in living animals.
From
Technology Review – Connecting a human brain to a computer is as much a materials science problem as a biology one. What kind of interface is delicate enough not to damage nerve tissue, but resilient enough to last decades?
Researchers have come up with what they call a “stealthy neural interface” made from a single carbon fiber and coated with chemicals to make it resistant to proteins in the brain.
The new microthread electrode, designed to pick up signals from a single neuron as it fires, is only about 7 micrometers in diameter. That is the thinnest yet developed, and about 100 times as thin as the conventional metal electrodes widely used to study animal brains.
