Pocket Breathalyser
If 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.
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.
