The AEEG electrolyte paste is a mixture of carbon powder and liquid binder that must be mixed by hand to achieve a uniform consistency. It is a combination of liquid binder with carbon powder that must be mixed manually to create a uniform texture. The resulting carbon paste is then packed into an electrode holder for use in a standard electroencephalography (EEG) head cap.
In EEG recordings there are several alternatives to traditional conductive past, but the performance of those materials hasn't been tested over a long period. Researchers conducted a study in which they compared the effectiveness of a carbon paste that was used to reduce artifacts from pediatric EEG recordings with traditional conductive tape. The results show that a new alternative is more effective at improving electrode impedance*. It also has better resistance to changes in skin temperatures and perspiration, which are critical for long-term EEG recording.
The electrode paste has traditionally been made from coal tar pitch, a by-product of the production of metallurgical ironmaking coke. CTP has been shown to contain carcinogenic components and could be restricted for some industrial applications in the future, but is still widely used as an electrode paste adhesive. The use of biocarbons as an alternative to fossil-derived coal pitch could be used in electrodes and refractory products, and reduce their environmental impact. The replacement of coal tar pitch in industrial carbon electrodes poses a material engineering challenge. It is necessary to tailor the rheological characteristics of the binder so that it flows and fills the electrode casing as the mass gradually bakes into a solid.
This study was designed to test an alternative carbon paste formulation that combines the benefits of CTP with a non-toxic, low-allergenic, biodegradable, vegetable oil based binder. The resulting formula is also easy for users to work with, and it provides a significant improvement in impedance compared to the traditional paste.
The LIC2(r) Electrode Cream is an ideal alternative to traditional conductive paste, which can be messy and is difficult to remove from the skin after application. LIC2 (r) is gentle for the skin, and it contains no alcohol. It's ideal for children. It can be used for areas that are inflamed or itchy and not suitable for traditional electrodes.
In the present study, 115 individuals were randomly assigned into either a collodion (traditional paste) or a traditional paste group. The average number electrodes with artifacts for the conventional paste was 8.2 second, which was comparable to that of the collodion. This study shows that changing to an alternative paste for electrodes can reduce artifacts in long-term AEEG recordings of pediatric patients. This improvement is more noticeable in recordings over 24 h.
