Rice University scientists have found that the carbon nanotube fibers they developed for aerospace are superior to metal and plain-carbon electrodes for deep brain stimulation for neurological disorders such as Parkinson’s and for brain-machine interfaces to neural circuits in the brain.
The individual nanotubes measure only a few nanometers across, but when millions are bundled in a process called wet spinning, they become thread-like fibers about a quarter the width of a human hair.
Strong as metal but soft as silk and highly conductive
“We developed these fibers as high-strength, high-conductivity materials” for aerospace applications, where strength, weight and conductivity are paramount, said co-developer Matteo Pasquali, a chemist and chemical engineer.
“Yet, once we had them in our hand, we realized that they ...
