Abstract
This invention addresses the need for efficient dry skin electrodes. Robust, flexible Mixed Ionic Electronic Conductor (MIEC) electrodes were prepared by an aqueous solution route resulting in electrically conductive networks of carbon nanotubes (CNTs) and ionically conductive elastic matrix. The flexible electrode was characterized in terms of conductivity, ionic charge transfer resistance, and water uptake. The flexible electrode maintained low resistance even after multiple cycles of 50% extension and contraction.
