Joule is a bracelet that drip feeds you caffeine. Seriously

If you’re fed up with queuing and spending money on coffee, why not get your caffeine hit in wearable form? Yes, that’s the promise from this bracelet, which gives you a steady supply of caffeine all day.

It sounds like a terrible idea. As if the whole of western civilisation isn’t already wired and anxious enough without a constant supply of caffeine directly entering our bloodstream.

Nevertheless, it’s certainly intriguing. Joule takes a transdermal caffeine patch – think of it like a nicotine patch for coffee lovers. The equivalent of one cup of coffee is administered gradually over a period of about four hours, giving you a steady boost rather than the high followed by a crash that you usually get with caffeine.

It also means you won’t have to queue at the coffee shop, put on weight from drinking coffee, or spend too much money (it works out about $1 or 69p a day). If the equivalent of one cup of coffee lasts four hours, many people will also cut down their caffeine intake by using the bracelet. As long as they’re not drinking coffee on top of it, of course.

It looks like a short-term solution to us. Surely it’d make more sense to eat more healthily, cut down on caffeine and get more exercise? Though if you don’t have the time or the inclination for that, we can see the appeal.

It’s raised over twice its funding goal and still has 18 days left. Pledge $55 (£38) and it can be yours when it ships in July.
