How It Works


Designed to be comfortable so that you can wear it all day and night. Ideal for those who want discreet options for monitoring and tracking their alcohol consumption.


A first-of-its-kind enzymatic sensor detects the presence of alcohol on the surface of your skin, after your body has consumed, processed, and released it through the skin. Once activated, the cartridge lasts for 24 hours.


Check your progress as often as you like with the ION™ App. Receive your sensor readings, such as Clear or Signal Detected, with frequent syncing.

ION™ uses patented non-invasive enzymatic alcohol sensing technology.  Cartridges can be replaced daily to overcome the fouling issues that have plagued previous generations of alcohol biosensors. To take a deep dive into how we are able to use enzymatic chemistry to obtain an unprecedented signal-to-noise-ratio, check out our peer-reviewed scientific journal article in the journal "Sensors".

Does ION detect BAC?

No, ION does not measure BAC. Each cartridge measures alcohol that has diffused through the skin. The app provides statuses such as 'clear' for no consumed alcohol or 'signal detected' for consumed alcohol.

I'm interested in getting ION for a loved one- will I be able to see their info and get alerts?

Yes, if they consent to share data with you,. you can see their data on your personal phone via the ION App. 

Can I remove the device myself?

Yes, the ION™ Wearable can be removed as needed to fit your schedule, for example for swimming or showering. There is a patented skin proximity sensor so the app will log 'insufficient skin contact' if the wristband is removed from the wrist.

Will anyone else be able to see my data?

At the moment, the wearer or owner of the main account can choose who they want to share to support group accounts.


Cartridge Features

Skin proximity sensors

Each cartridge has 2 sensors to measure skin proximity

small form factor

Each cartridge is the size of a small coin

Easy click activation

Fold the clamshell closed until it makes a 'click' sound to activate! Enzymes are active for 24 hours once activated. 

6 month shelf life

ION cartridges are stable for 6 months until activated.

NIH awarded

ION™ has been developed with support from more than $2 million in federal government grant funding from the National Institutes of Health (NIH).

From raw data to signal detected

ION™ uses proprietary machine learning and AI to convert the raw alcohol sensor signals created by our sensor cartridges into an easy-to-read Signal Detected or Clear. Click on any day in the ION™ Calendar* to see your history for that day with 30 minute resolution.

Continuous monitoring

ION does not have set 'testing windows' that may interrupt your activities while you are on the go or in public. Just change the cartridge once per day, any time you like, and ION™ wristband detects signals for you every step of the way. Take a break to jump in the pool or shower while your wristband charges and syncs at the same time. Just leave your wristband plugged in for up to 45min and press sync in the ION™ App.

Skin Proximity Sensing

Two skin proximity sensors in each cartridge monitor that the alcohol sensor is against the skin. Removing the wristband results in a status of “insufficient skin contact” for that 30-minute interval.
