Alcometer

f you drink alcohol don't operate a vehicle. But the reality is that people rely on their own sense of sobriety if they have a glass of wine at a restaurant or a couple of beers during a sporting event.
The fact that blood alcohol levels differ for every person is what inspired this invention.
The iBAC alcometer is a thumb-sized, portable, breathalyser spectrometer that measures your blood alcohol content similar to tests done at a laboratory.
Here's how it works.
It transmits the breathalyser reading to your smartphone via Bluetooth where an application containing your bio data (such as your weight and other physical characteristics) analyzes the results in about a minute.
It will measure your degree of sobriety, your alcohol burning rate and will even forecast when you will have a zero level of alcohol in your body.
