tDCS Sponge Insert Replacements

These Sponge inserts by Caputron are used as replacement sponges and come in different sizes. The 2"x2" and 3"x3" square sponge inserts fit into their respective size electrodes from Caputron. The 1.5" round sponge inserts fit both the Brain Premier and BrainDriver electrodes. Pack comes with 10 sponge inserts. It is important to properly maintain electrode sponge inserts in order to obtain consistent and uniform current distribution throughout the tDCS electrode, this minimizes the chance of current “hotspots” where current may tend to concentrate at certain areas of the electrode sponge surface due to the constant wear and subsequent degradation of the sponge material through usage—this results in inconsistencies in current density distributions. As a result, it is advised that you replace your electrode sponge inserts every 3-4 uses. These sponges come dry. As soon as one applies saline solution to them, they immediately absorb the solution and expand. Th
