A solid gel electrode or an electrode with wet gel?
The many different examinations within clinical neurophysiology each have their special requirements for electrode characteristics. Therefore, the choice of electrode type must be based on the actual recording conditions. Solid gel electrodes are made of soft and flexible materials, which make them suitable for examinations of children as well as for use on the face near the eyes or ears. Furthermore, the electrodes are repositionable making them very cost-effective in cases, where registrations are made from different sites on the same patient, for instance in Nerve Conduction Studies. The adhesive strength of a solid gel is not as strong as that of the adhesive used on a wet gel electrode. This is, however, partly compensated by the fact that the electrode adheres across the entire surface and not just around the sensor. When using solid gel electrodes it is important to prepare the skin carefully before positioning the electrode. Wet gel electrodes achieve a faster electrical contac
