Taking the Guess out of Hydration


Because athletes don’t have a way of effectively monitoring their hydration status during a workout, they often misunderstand how easily and quickly it can occur.

Managing hydration is complicated by a high degree of variability in sweat rates. It is obvious that each individual sweats at a different rate based on individual factors like gender, body mass and fitness level, among other factors. But for any individual athlete there are a number of additional variables that impact sweat rate from weather conditions to the intensity of the workout, to the amount and types of clothing or equipment worn. The same athlete can have different sweat rates for the same activity on any given day.

Given the lack of a consistent, reliable hydration management system, people must rely on difficult, unfeasible or unreliable hydration methods.


Our lightweight biosensor continuously measures sweat throughout your workout and sends personalized notifications to your phone, watch, or bike computer in real-time to tell you when, what, and how much to drink, ensuring that you stay properly hydrated.

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.


Nix Biosensors seem to be a fairly intuitive concept given the technology and accessibility currently available. This was one of the first ideas that came to my mind when reading the prompt as well. It’s small, lightweight, easy to use and connects with your smartphone. But my question is if a wearable device such as this, which reminds me a lot of those used to monitor diabetes, is possibly too invasive for the average person. I’m not sure I could see most people applying and wearing a sensor like this everyday that makes no effort to blend into a normal outfit or appearance. It works for short workouts and for athletes but nothing past this. I do like the app interface though.
