Keywords:Neural electrodes, Printed electronics, Polymer nanosheet

We developed neural electrodes composed of tens-of-nm thick polymer nanosheets and gold lines. Gold nanoinks were inkjet-printed on the surface of polymer nanosheets to form conductive lines (Width: 50 µm). Then, the electrodes were exposed by cutting the edge of printed gold lines with a razor. Neuronal activities were successfully recorded by injecting the neural electrodes covered with an insulating polymer into brain tissues.
