Ever wake up from the night before with a bit of a sore head and think never again?  Yeah, us too.

But thankfully hangovers could soon be a thing of the past due to a brand new gadget which tells you when to stop drinking before you reach a hangover-earning state.

The new Bactrack Skyn wristband measures the amount of ethanol coming from your skin using an electrochemical sensor in a non-invasive way and sends an alert to your smartphone when that level has reached a certain point.

The world's first wearable alcohol monitor not only collects data about the levels of alcohol in the blood but also stores and interprets that information before sending it to a smartphone which will alert the wearer of the band’s findings.

The owner’s phone can be set to buzz when their blood alcohol content is approaching a figure like 0.04% to warn them to slow down.

According to Bactrack Skyn's website, the device could also be used by the family members of alcoholics as a warning that sobriety has been broken.

Because the wristband measures blood alcohol levels continuously in real time, it can tell you when you’ve had enough to drink before you even realise you have.

Bactrack Skyn was recently awarded $200,000 from the National Institute of Health in the US and will be available for purchase later this year.
