Meet Joule: a cool bracelet that lets you use caffeine patches to stay energized throughout the day and avoid crashes. It uses a transdermal caffeine patch that works similarly to nicotine patches. The caffeine is released gradually, so you don’t experience the negative effects of consuming too much caffeine.
The Joule bracelet delivers about 65mg of caffeine per patch. The patch does not affect your skin negatively in any way. More information is available here.
