Inventors have unveiled a solution for caffeine fans which will say farewell to stained teeth, coffee breath and wasted lunch breaks queuing at Starbucks.
A new caffeine bracelet is set to revolutionise the way we turn to a cuppa for a boost - instead feeding us the stimulant through our skin.
The Joule comes as a durable silicone bracelet or a watch, and works using a process called transdermal administration of chemicals.
It is similar to how Nicorette patches work.
The caffeine would be embedded in an adhesive patch which would provide a controlled release "through the user's skin as their body heat melts away the thin layers of formulation", Joule explains on its Indigogo crowdfunding site .

Although transdermal delivery only works with chemicals with molecules small enough to penetrate skin, caffeine is both fat soluble and small, so it's ideal for this purpose.
Don't worry about getting too jumpy.
"Joule has roughly the same caffeine content as a cup of coffee but administered over four hours so the amount being taken up by your blood stream will not be a shock to your system any means if you already enjoy caffeine regularly," they explain.
But don't worry - if you're a cafetiere bore of you just like brewing up, you can use Joule together with the traditional cuppa.
Currently the campaign has raised almost £30,000, more than 280%
Invented by Adam Paulin - a personal trainer with a B Sc Hons in neuroscience and psychology and launched together with Alex Kryuk, a medical doctor with a Ph D in medicine, Joule could be changing the way we meet mates for a coffee and a catch up from here on.
