Design optimization methodology for dry EEG spikes array electrode

Monitoring bio-electric events is a vital practice which provides medical data required in many clinical and research applications. Improving the performance of portable and ambulatory recording devices requires developing stable biomedical electrodes suitable for long term recording. This paper introduces an optimization design methodology to improve the electrical performance of dry electrodes used in electroencephalography through optimizing the geometrical design while abiding by design constraints which guarantee biocompatibility and mechanical stability.
