It may sound like science fiction, but the caffeine bracelet is very real.

The new bracelet called Joule is a crowdfunded startup project on Indiegogo which is the closest existing thing to an IV drip of coffee. Joule works along the same concept as a nicotine patch; an FDA-approved transdermal caffeine patch is placed in a slot on the inside of the bracelet and the caffeine is absorbed directly into the bloodstream through the skin. Each Joule patch lasts about four hours and contains roughly the same amount of caffeine as a medium cup of coffee (about 65mg).

Joule starts working as soon as it comes into contact with the skin, and the caffeine is absorbed faster through this transdermal method than through oral administration such as drinking coffee. Due to the slow release and constant flow, the Joule bracelet can help users avoid the infamous caffeine slumps and jitters that come with coffee consumption.

At $29 for the bracelet and starter kit of 30 patches, it can help caffeine lovers save on the considerable expense of ground coffee and single-serving coffee or tea pods. Refills for the patches will cost about $27, so the creators estimate the total will come to less than $1 per day. To top things off, there’s even a watch version you can get for a pledge of $99 if you’re into that.

“Joule was created to help caffeine consumers emphasize the highs of their caffeine consumption experience while eliminating the lows,” Adam Paulin, a cofounder of Joule, told Tech Insider. “All while looking stylish.”

The Joule strap is unisex, sweat-proof, and hypo-allergenic, and adjustable to fit any wrist size. Right now it is made of a silicon material and comes in pink, black, and blue. Other ingredients in the caffeine patches include flaxseed oil, bladderwrack seaweed, and several amino acids. The adhesive patches are made with guarana extract, which has a caffeine concentration roughly twice that of coffee beans. Bustle characterizes the possible advantages of the Joule bracelet.

“Also consider the other perks: it won’t have you running to the bathroom every 15 minutes (#guilty), it won’t be acidic on your stomach, and it won’t yellow your teeth the way coffee does. Plus you won’t be holding a fist up to your vengeful gods every time you open the office fridge and see that someone finished off the last of the milk you typically drown your coffee products in.”

The creators of Joule also emphasize the problem of multi-tasking while drinking coffee or tea, particularly when performing tasks like exercising, typing, walking, or riding public transportation. It also contains no calories and won’t stain teeth. Though if you’re hesitant to give up that hot morning cup of joe, it can be safely combined with your usual coffee, tea, or energy drink and still help avoid crashes later.

“As you might imagine, we feel that the Joule Caffeine Bracelet is perfect for anyone who relies on coffee or energy drinks to supply energy for alertness and getting things accomplished,” Joule says on their page.

Joule managed to raise $4,168 of its $15,000 goal in just the first 23 hours. There are 22 days left for Joule’s campaign, and they offer several perks in exchange for pledges. They promise that many new formulations are still on the horizon should the project succeed in getting funding, including weaker and stronger doses of caffeine.

The bracelets won’t be ready to ship until July, but they are currently available for preorder on Joule’s Indiegogo page.
