When you're out on the town, checking alcohol levels in your blood with a breathalyzer probably isn't part of the programme, but there is a way to do it discretely, if you wish so.
California-based Milo Sensors is creating the next generation of wearable biosensors that gain blood-level insights in a non-invasive way. Proof will able to detect alcohol molecules right through your skin via enzyme-based electrochemical sensor. The sensor momentarily converts alcohol into an electrical current, but the entire point of this supersoft wristband is to continuously track a wearer's blood alcohol level, so one knows right where one stands at all times. Powered by a rechargable battery and equipped with a disposable cartridge, it can automatically track alcohol content for 12 hours straight. It uses smart LED and vibration alerts to notify the wearer of increasing alcohol levels, as per pre-selected BAC levels.
With this information, people can hopefully make better decisions about driving home or having someone come and pick them up. In such a case, Proof is a potentially life-saving wearable for a smarter night out.
Proof is expected to go on sale later in 2017. It will cost you between $100 and $150.
