Previous generation EXG systems required 3 adhesive electrodes per channel. Common brand conventional electrodes retail for about $0.25 per electrode – $0.75 for one channel of EXG. Somaxis Patches are also $0.75 for one channel of EXG (or less, depending on volume).
Patches are extremely convenient and intuitive to apply. Any muscle group of sufficient size may be measured, anywhere on the body.
Patches are made from hypoallergenic materials including water-based hydrogels of the same high quality as is used in fetal ultrasound hydrogels. Patches have a two year shelf life, are rated for single use, and are individually labelled with expiration dates.
