In this brave new world of mind-altering headgear and body-monitoring smart clothing, there seems to be no such thing as a wearable we won't consider. Enter Joule, a coffee serving bracelet which uses transdermal caffeine patches to 'deliver' caffeine to your body in doses lasting up to four hours.

It's not exactly a smart bracelet but it is very connected self. The idea is that you get a constant and even supply of caffeine throughout the day to avoid energy spikes and crashes, mood swings and blood sugar issues. Plus Joule's Indiegogo campaign, which is already a third of the way to raising its $15,000 goal, lists not having to wait in line as another perk of the product.

The actual caffeine is administered similar to a nicotine patch, according to Joule's page - it is released through your skin on the inside of your wrist, body heat melts away unnecessary layers and the caffeine can make its way through to your blood stream. Another supposed benefit? No more stained teeth.

In theory, the Joule bracelet could be used the same way as a nicotine patch, to help you cut down on coffee or fizzy drinks if you've been advised to. Chances are though that this will only fuel our obsession with coffee.

Joule is available to back on Indiegogo now for $29 for a starter kit which includes 30 days of replacement patches. Further packs of patches cost $27 each and estimated delivery is July 2016, worldwide.

How we test

A fan of thoughtful design, innovative apps, and that Spike Jonze film, she is currently wondering how many fitness tracker reviews it will take to get her fit. Current bet: 19.

Sophie has also written for a host of sites, including Metro, the Evening Standard, the Times, the Telegraph, Little White Lies, the Press Association and the Debrief.

She now works for Wired.
