To order, or not to order another margarita? How many have you had, two, or three maybe? Should you call a cab home maybe? All of these questions would be much easier to answer if you only had a simple way to concretely measure just how much alcohol is flowing through your bloodstream. Would a breathalyzer work? Of course. Would you feel comfortable whipping out a breathalyzer in the middle of cocktail hour? Not likely.

So ultimately you must rely on your good judgment to gauge how inebriated you might be. Unfortunately, alcohol and good judgment are rarely seen together. Enter Evan Strenk. His new company Milo Sensors is betting on your discomfort. The flagship product of his tcompany is a revolutionary new wearable called “Proof”, which claims to monitor BAC on your wrist in real time, and discretely. The device is able to monitor your vitals and BAC by detecting various chemicals you secrete in your perspiration. The sensors on the wristband measure these chemical levels and provide you with an instant readout on your wearable, or on your smartphone through their user friendly app.

The wristband operates using disposable cartridges. You put on your wristband, load a cartridge before you head out for the night, and that’s that. After the evening is over, you simply eject and dispose of the cartridge until your next use. The device can also be configured to alert you when your BAC has reached a predetermined value so you can better track your drinking as the night progresses. On paper it sounds like a fantastic idea. However, before I place my pre-order, I’m going to need a bit more…..proof.
