DESIGN


DESIGN


Inspiration

Inspired by the neon wristbands often distributed at the entrances of bars, music festivals, and venues, the RXN wristband is an affordable, functional design that fits seamlessly into existing systems.

PROBLEM

The RXN wristband seeks to reduce America’s fourth highest preventable cause of death. An estimated 88,000 individuals die each year from alcohol-related causes. Nearly a third of all US traffic-related deaths involve a driver under the influence.

SOLUTION

To design an alcohol biosensor that can be manufactured so cheaply that it can be given away by bars, music festivals, event organizers, and venues. To improve the cultural landscape surrounding drinking and encourage a climate of personal and social responsibility.

FOR BUSINESSES

We intentionally designed the RXN wristband as the perfect sidekick for bars and music festivals. We know how important it is to keep customers safe. The RXN wristband is designed with both cost and function in mind. Our customizable production system allows us to produce large quantities, quickly and at low cost.

How does this thing work?!

We use a naturally-produced enzyme that detects ethanol - the primary alcohol found in beer, wine, and spirits. It's the secret ingredient that we use to instantaneously and non-invasively measure BAC.

Why We Ferment

In order to produce our RXN wristbands at scale, we produce our enzymes using a fermentation process very similar to brewing beer. That's why we can produce so many RXN wristbands so quickly. Once we have all of our ingredients, we use a unique fabrication technique to produce each and every RXN wristband from natural, sustainable materials.

Safety and The Environment

One of the major design considerations going into this product was whether or not to make it reusable. There are many pros and cons to either approach; however, the one consideration we all agreed upon was user safety. Ultimately, by making the RXN wristband single-use we are better able to ensure consistent and reliable quality control, which translates to less false positives and negatives and a safer experience for our users. All components of the RXN wristbands are 100% biodegradable and are primarily derived from natural and sustainable bioprocessing techniques.

FAQ


FAQ


Seriously...does this thing work?

Yes! Since we use biological (rather than electronic) components in the design the RXN wristband doesn't need batteries. Additionally, the Ember team has confirmed through (highly enjoyable!) product testing that the RXN wristband works.


What's the shelf-life?

Up to 10 days at room temperature.


How long does it Glow?

Up to 8 hours after activation.


What about safety?

We've spoken with hundreds of potential users throughout our design process. We think we've identified and addressed the most common safety concerns through industrial design solutions that will be implemented in the final version of the RXN wristband:

  • No, it won't hurt you!
  • The design of the RXN wristband intentionally discourages "race-to-get-drunk" drinking games. It does this by turning "on" or "off" and will not glow brighter, nor indicate a change in any way, in response to increased alcohol use.
  • The final industrial design of the RXN wristband will allow users to discreetly know they are intoxicated without publicly broadcasting it to everyone around.
