PALS Foam neurostimulation electrodes combine the same revolutionary patented stainless steel knit fabric and hydrogel construction as standard PALS electrodes, but PALS foam electrodes include a soft foam top. The patented conductive stainless steel knit fabric provides the ultimate in flexibility and conformity while ensuring optimal current distribution. PALS Foam electrodes feature Axelgaard’s patented multi-layer MultiStick hydrogel, which provides comfort and multiple applications to the skin.
