New technologies for in-flight pasteless bioelectrodes

Advances in development of in-flight electrophysiological-based systems such as G-LOC detectors, ECG-synchronized G-suits, and clinical monitors have dictated the need for pasteless electrodes that meet realistic operational demands and are suitable for the cockpit environment. New technologies appropriate for the design of bioelectrodes that meet these demands are described, including a stable dielectric electrode-skin interface material, miniaturized high-impedance electronics, and circuit fabrication methods. Design examples and resulting electrophysiological recordings are presented to demonstrate the new technologies.
