A bracelet with a transdermal caffeine patch will allow you to absorb caffeine through the skin on your wrist. Each caffeine patch is equivalent to one cup of coffee and lasts for four hours. The Indiegogo page for the bracelet already raised almost $40,000 — 257% more than the original goal of $15,000.
