Your Sweat Could Soon Charge Your Phone

Written on August 20, 2014 at 10:09 am , by

Major #fitnessgirlproblems: when your struggling smartphone never seems to stay charged past the one-mile mark, leaving you music-free and potentially data-less. The solution? It could be those beads of sweat you’re forming.

A team of researchers at the University of California San Diego have created a sticky, temporary tattoo that acts as a bio-battery and uses lactate to generate power. Where does the battery get lactate? Right from your sweat.

“We’re trying to use our own body to generate power,” says Wenzhao Jia, Ph.D., postdoctoral researcher at the University of California San Diego who led the project. “This happens when sweat contacts the bio-battery, and it’s less toxic than a [standard] chemical battery.”

But there’s one caveat: if you tend to be a heavy sweater, you can’t assume your device will be ready for an Instagram spree. “You won’t necessarily be creating more power,” explains Jia. In fact, it’s the other way around. The harder your body works, the more lactate it produces. In other words: “The fitter ones produce less power; the less fit make more,” she says.

While this form of power serves up some motivation to push through that last set, Jia says she and the team still have a long way to go before the bio-battery becomes powerful enough to charge electronic devices. Still, it’s an interesting development we’ll anxiously be tracking. Who needs wall outlets these days, anyway?

The Fitness Gear You Don’t Have (But Really Need)

When we think of Bluetooth chips, we usually don’t think of them in relation to water bottles. And when we think of yoga mats, we usually don’t think sensors and LED lights will be involved. But with personal trainers continually developing new ways to crank our calorie burn, and nutritionists creating new recipes that are easier, tastier and healthier, it’s no wonder the products meant to streamline our journey to a healthy lifestyle are nearly lapping the experts in innovation. These soon-to-be available high-tech gadgets are meeting—and potentially exceeding—our expectations, and you better believe they’re on our wish lists! Check ‘em out:

Dehydration affects nearly half of us, which is how the creators of BluFit came up with its concept. It’s a glass water bottle that syncs with your phone to keep track of how much water you need (based on weight, age, humidity levels, etc.) and how much water you drink. When it’s time to grab another sip, BluFit alerts you via sound and light to drink up. Not near your water bottle? It’ll alert your phone, too. The rechargeable battery lasts for about six days, so you’ll be good to make this little guy your running buddy or your staple between gym sessions.

A yoga class in the comfort of your own home? Sign us up! That’s basically what the Tera mat provides. Also a wool carpet, the mat uses sensors to identify where you are on the mat and guide you where to go next based on each workout you do. You can even tailor the workouts to help you reach your personal fitness goals. The mat syncs with the Tera app to record and analyze your movements, while the app itself provides step-by-step guides for completing each movement correctly. You can also use the mat for Zumba, Pilates or Thai Bo. Versatile, convenient and stylish? Talk about every fit girl’s dream!

Look and Train Like an Olympian

Although the Olympics are officially over, we can’t help but miss all of the excitement (and inspiration!) this year’s athletes brought to our televisions. We may not have the stroke of Missy Franklin or speed of Allyson Felix but we can still try to train and outfit ourselves like our favorite champions. If you’re still burning with Olympic fever, we have the best games gear that will encourage you to go for whatever “gold” you set.

Patriotic Pool Wear – Swede Arne Borg became the first Olympic Gold Medalist to win in a Speedo back in 1932. Since then, the world’s top-selling swimwear brand has been lapping competition with their innovations. This summer, Speedo outfitted the entire US swim team with the latest performance technology, the Fastskin3, which improves hydrodynamics and reduces drag. Not looking to make the $595 investment? The 2012 Team Speedo Collection commemorates the Olympic games utilizing their Endurance+ training suit fabric. This stretch technology and cut lasts 20% longer than traditional suits for a more affordable $82!

“Dimples,” a Good Thing – According to a recent British study, sneaks with “dimples,” or fabrics replicating the texture of a golf ball, resulted in an overall better aerodynamic performance. We think the Reebok DMXRide, Nike Zoom, Nike Free and Nike100km are all great examples of the running shoe design found to affect both energy consumption and finishing time. Looking to strut your stuff in kicks clad in stars and stripes? Check out the gold-worthy Saucony’s commemorative Women’s Jazz Low Pro Medal collection and ASICS Red, White & Blur Limited Edition Gel-Bur33!

Break PRs – Track events often come down to hundredths of a second and that means sprinters, especially, need lightweight spikes to help their traction. Puma’s Usain Bolt evoSPEED Sprint LTD Spikes are flexible, while offering optimum grip, stability and Jamaican pride. Tyson Gay, who took home silver in the Men’s 4x100m relay, preferred the adiZERO Prime SP by Adidas, which weighs in at just 3.5 ounces thanks to the seamless upper SpringWeb.

Have a Ball!Arguably one of London’s biggest nail biting match-ups was when reigning champs Kerri Walsh and Misty May-Treanor took on fellow Americans, Jennifer Kessy and April Ross, in the final women’s beach volleyball match. You, too, can bump, set and spike like the fab ab duo with Kerri’s favorite Oakley shades, the Commit SQ in Black, known for its lens clarity. The official Olympic Volleyball game ball is now also available by Mikasa.
