Game Changing New Technology

Nix Hydration Biosensor. The first of its kind.

Nix Hydration Biosensor

No more trial and error to identify your optimal hydration strategy. Our revolutionary hydration biosensor platform quantifies fluid and electrolyte losses moment-by-moment and sends notifications to your phone, watch, or bike computer to tell you exactly when, what and how much to drink. So you can focus on what really matters - your workout.

Scientific: Evaluates the biomarkers in your sweat, like a portable lab without the needles.

Personalized: Analyzes your sweat moment to moment, not a generic calculation.

Actionable: Quantifies when, what, and how much to drink in real-time during your workout.

Convenient: Integrates with your phone, watch, or bike computer. Lightweight and easy to use.

Lightweight Electronic

Our revolutionary hydration biosensor weighs less than 0.5 ounces and is similar in size to a Garmin watch face. The electronic pod is durable, reusable, and built to last. The pod clips onto a single-use sweat patch and transmits data to your phone, watch, or bike computer every second.

With battery life of up to 36 hours, this biosensor can withstand your longest training sessions and help you reach your peak performance.

Innovative Sweat Patch

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.

The patch is single-use only.
