DrinkMate is a tiny, plug-in-alcohol device for Android devices that can be plugged into smart phones, and smart devices that add phone functionality through built-in sensors are constantly pouring into the market, many of which are supported by crowdfunding methods. Now another competitor in this field, the BlowMate Inflatable Alcohol Tester, wants to extend the capabilities of Android smartphones and is currently raising funds on the crowdfunding platform Kickstarter with a target of US$40,000. It is expected that the product will Into the market in December.
The 1.8-inch long device can be plugged into the phone's micro-USB port for use with a matching application. When the user blows into it, the semiconductor-based sensor displays the blood alcohol content (BAC) rating on the screen. DrinkMate does not require a mouthpiece. The user only needs to blow air into the air intake. This design helps to ensure the compact structure of the product and the hygiene of the equipment.
We've seen blew breath alcohol detectors for smartphones before, such as the larger Alcohoot that we reported last year for iPhones. However, DrinkMate is a lot smaller and much cheaper, which is the track following Moore's Law.
DrinkMate also claims to have higher accuracy, with a measurement accuracy of ±0.01% when the BAC level is 0.02%. Obviously this feature is the key to this device, but after all this is just a prototype, so this statement remains to be tested. DrinkMate's sensors have a maximum measurable blood alcohol concentration of 0.20%, but if you're already drunk to that extent, you're less likely to be conscious about using this gadget, let alone find your car key.
In addition to the level of precision, in real life, there are a wide variety of drinks, and users may not follow the best inspection process. It remains to be seen how DrinkMate will perform well in an unpredictable, real-world environment. Maybe in the future, a matching application will be needed to avoid misleading readings. This application can track potential user errors, such as ensuring that they wait long enough for alcohol testing after the last drink to avoid inaccurate Rating (concentration is based on mouth alcohol).
The makers of DrinkMate in Washington, DC, said that the basic idea behind the device is to generate a visible, sharable BAC review to create more peer pressure among drinkers so that they can guarantee each other’s Safety. This is a commendable goal, but there is also the risk of encouraging the opposite behavior - so the tone of the application is very important. The design of current applications is very simple, but producers say they will add more features every week.
