WEARABLE SWEAT INTELLIGENCE
Know WhatYou Lose.
See how much fluid and sodium you are estimated to lose during exercise. NAESIA is developing wrist-worn sweat sensing to help you understand your training.
Whole-body estimates · illustrative session
PRECISION SENSING. PERSONAL INSIGHT.
YOUR BODY. YOUR CONDITIONS.
Every athlete sweats differently.
Training intensity, conditions and your own physiology affect how you sweat. Compare workouts to learn what changes for you.
Sweat rate
Follow the estimated rate of fluid loss across your body as the workout progresses.
ESTIMATED · L/hSodium loss
Track estimated sodium loss in grams, alongside the amount of fluid you lose.
ESTIMATED · mg or gYour sweat profile
Compare sessions to see how your sweat response varies across workouts and conditions.
PERSONAL · OVER TIMEMEET THE SYSTEM
Small wearable. Clearer data.
A fresh cartridge collects the sample. A reusable reader captures the signals. The app helps you follow losses during training and review them afterwards.
The cartridge REPLACEABLE
A microfluidic cartridge collects sweat at the skin and measures sodium in that local sample.
The reader REUSABLE
Reusable electronics read the sample’s signals and send local sweat measurements to the app.
LESS FRICTION. MORE UNDERSTANDING.
Ready. Set. Know.
01Attach
Connect a fresh cartridge and fit the wearable against your skin.
02Move
Start the workout in the app and train as you normally would.
03Sense
Fresh sweat enters the microfluidic cartridge as you exercise.
04Understand
Follow estimated fluid and sodium losses, then review the session afterwards.
COASTAL LONG RUN
Live workout
Whole-body estimate
DURING TRAINING. AFTER TRAINING.
Understand your losses.
Follow estimated fluid and sodium losses during your workout. Afterwards, compare them with what you drank to support hydration and recovery planning.
- Sodium concentration measured in the local sample
- Estimated whole-body fluid and sodium losses
- Session results to support recovery planning
Measured locally: sweat sodium concentration and channel flow information.
Estimated for your whole body: sweat rate, fluid loss and sodium loss.
SMART HYDRATION ALERTS
A checkpoint. With context.
Account for what you drink as well as what you lose. Compare your estimated net fluid deficit with a configurable percentage of starting body weight.
2.00 L sweat loss − 0.50 L intake
≈ 1.50 kg estimated net loss · 2.0%A 2% checkpoint is an advisory setting, not a universal medical danger threshold. NAESIA does not directly measure body mass or diagnose dehydration. Starting weight and a complete intake log are required. Unknown additional changes are labelled as a partial estimate.
SMART HYDRATION ALERTS
Hydration checkpoint
Of starting body weight · model-derived
Illustrative estimate · other changes assumed zero.
Advisory checkpoint reached.
Your estimated fluid deficit has reached 2% of your starting body weight. Review your hydration status and fluid intake.
BEYOND A SINGLE WORKOUT
Find your rhythm. Then your patterns.
Compare a long run in the heat with an easy session in cooler weather. See how fluid loss and sodium loss differ, rather than assuming they always rise together.
A different day. A different story.
Five simulated sessions show different conditions and sweat responses.
