Nix Hydration Biosensor | Sweat Analyzer + Personalized Hydration Data

Take the guessing game out of your hydration strategy. The Nix Hydration Biosensor is a first-of-its-kind wearable that analyzes your sweat and gives you personalized hydration data.

This simple stick-and-go patch monitors specific biomarkers in your sweat to measure fluid and electrolyte loss to give you personalized hydration metrics. It can send real-time notifications to your phone, watch or bike computer telling you when, what, and how much to drink.

Since launching at the end of 2022, Nix has made significant improvements to their software. They’ve drastically improved connectivity, reliability and ease of use. They are continuously improving their app to ensure reliability and app health updates.

The Experience

Firstly, the packaging is incredible and the biosensor has a surprisingly great build quality. It’s simple to set up and get activated before a workout. The pod clips onto a single-use, disposable sweat patch. Just attach the patch and go.

After testing the device, we found you will need to be pretty sweaty before getting a reading (note it takes ~25 minutes to get your first data update). We suggest you use the device during a high-intensity workout or a workout that is at least an hour because the patches are single-use, and your training could become expensive.

Another highlight is you can act quickly based on the real-time data and see how your sweat composition changes based on internal and external factors; this allows you to adjust what you are doing during your workout. You can opt to receive real-time fluid loss notifications during your workout if your phone is within Bluetooth range 

How Nix Biosensors Work:

• Input what type of workout you’re doing and where (indoors or outdoors), along with what you plan on drinking into the app.

• Once you start sweating (for me, it took quite a bit of sweat and ~25 min.), the patch measures and analyzes your fluid and electrolyte losses per hour.

• Your sweat and respiratory data is streamed to the Nix app and can be shared across your iOS or Android devices.

• After your workout is complete, a post-workout summary provides intel that is designed to inform your hydration strategy going forward. The data provided includes total fluid losses, total electrolyte losses, and sweat composition.

You can also access a list of hydration products organized by electrolyte composition and identify the option that best matches your needs.
