Electroencephalography (EEG) recordings can be used to help paralyzed patients by replacing functionality of damaged neural connections
through the aid of a brain–computer interface. Conventional electrodes used for EEG require long skin preparation due to the
impedance of the outermost layers of skin. On the contrary, dry spiked electrodes allow overcoming of impedance problems and can be
suitable for long-term measurements. This paper describes microfabrication and packaging of micropatterned dry electrodes built with deep X-ray lithography, electroplating and soft lithography. Preliminary measurements performed with electrodes having different geometries
are also described.
