Recommended for workouts of 45 minutes or longer, the Nix Hydration Biosensor is a lightweight durable hydration monitor that quantifies when, what, and how much to drink to maintain proper hydration while analyzing your sweat moment-to-moment.

The rechargeable pod clips onto a single-use sweat patch before the start of each workout to read and transmit data to the Nix app. It integrates with your smartphone or watch to deliver personal hydration data in real time providing hydration intelligence to improve your athletic performance, safety, and wellbeing.

INFINIT Exclusive!  Quick Consult + Custom Blend Setup — Share your Nix hydration report through our Quick Consultation request form for personalized Custom Hydration blend recommendations.

We recommend wearing a patch during a sweat-inducing workout, ideally running or cycling, lasting at least 45 minutes in duration. After your workout is complete, a post-workout summary in the Nix App provides intel that can help inform your hydration strategy going forward.

Starter Kit includes a rechargeable pod, a charging case, charging cord, and 4 sweat patches (refills available here).

*You must be actively sweating for the device to gather data.


The hydration biosensor comes with a rechargeable pod (weights less than .5 ounces), a charging case, a cord, and 4 sweat patches.

Sweat patches measure just under 2.75 inches in diameter.

Made with medical grade, latex-free adhesive.

Patch should be disposed of after each workout and should not be worn more than once, as this can lead to inaccurate data.

Battery life lasts up to 36 hours.

Product Questions

I’m a 73 year old aircraft mechanic/tech in East/Central Florida where 6-months out of the year, humidity is greater than 90%, and heat index ranges from mid-90’s to 125! During the four hottest months, I average 1.25 gallons of water/diluted hydration drink per day and I’m still chronically dehydrated! Will this system help me during these hotter months?

Thanks for your question. Yes, the Nix Biosensor can definitely be used for workplace conditions that result in high sweat rates and electrolyte losses that lead to dehydration. The Nix Biosensor will help you determine how much you are sweating which will help you determine how much you need to drink to minimize the effects of dehydration. Let us know if you have any other questions.

Hello. Does this analyze the volume of sweat, salt concentration in sweat, or both? I understand that a person can sweat a lot but not necessarily lose salt.

Thank you

The Nix Biosensor measures your total and hourly sweat rate, your total and hourly electrolyte loss, and your electrolyte composition (mg/oz). It does not specifically measure sodium/salt loss but we can extrapolate the electrolyte loss to provide a sodium/electrolyte recommendation based on your results.

And yes, actual electrolyte composition can vary widely from person to person and you can be a heavy sweater but have a lower electrolyte loss. The Nix Biosensor would be a great way to find that out.
