    "abstract": "We describe the concept of a dry electrode sensor for biopotential\nmeasurement applications (ENOBIO) designed to eliminate the noise and\ninconvenience associated to the use of electrolytic gel. ENOBIO uses\nnanotechnology to remove gel-related noise, as well as maintaining a good\ncontact impedance to minimise interference noise. The contact surface of the\nelectrode will be covered with an array/forest of carbon nanotubes and will\nalso be tested with an Ag/AgCl coating to provide ionic-electronic\ntransduction. The nanotubes are to penetrate the outer layers of the skin, the\nStratum Corneum, improving electrical contact. We discuss requirements, skin\nproperties, nanotube penetration and transduction, noise sources, prototype\ndesign logic and biocompatibility. A future paper will report test results.",
