A step toward better brain implants using conducting polymer nanotubes

September 30, 2009 | Source: PhysOrg.com

Brain implants developed at the University of Michigan are coated with nanotubes made of poly(3,4-ethylenedioxythiophene) (PEDOT), a biocompatible and electrically conductive polymer that has been shown to record neural signals better than conventional metal electrodes.
