The proprietary Nix patch detects electrochemical biomarkers in your sweat.

Once you start sweating, your sweat rate, electrolyte loss rate, and sweat composition are measured in the flow channel. The patch sticks onto the surface of the skin with kinesiology tape for flexible adhesion and comfort.


Each  patch is single-use only.
