Daniel Cooper09.03.2021Gatorade made a sweat patch to track your perspiration
The composition of your sweat can tell you a lot about what your body needs to recover after a workout. The problem is, it takes a lot of effort for anything to register on Gatorade's Gx sweat patch.
Cherlynn Low03.08.2021Wearable gauges fitness through stress hormones in your sweat
Cortisol (best known as the stress hormone) is handy for tracking your athletic performance and even spotting signs of disease, since it reflects how well your adrenal or pituitary glands are working. But there's a problem: measuring that often takes several days of lab work, by which point the info is no longer relevant. Scientists might have a much better option. They've developed a flexible, wearable sweat sensor (not shown here) that tracks cortisol levels with results in seconds -- that is, while it's at its most useful. It sounds straightforward, but the team had to overcome a major obstacle common to most biological sensors.
Jon Fingas07.20.2018Body sensor collects vital data by making you sweat
Medical sensors that sample your sweat are great, as they can accurately gather some of the data you'd get from blood without having to poke through your skin. There's just one problem: this usually means going for a run or otherwise doing something taxing to produce that sweat. However, researchers have an elegant solution. They've devised a relatively small sensor (about the size of a Band-Aid) that stimulates the sweat glands on a small patch of skin so that you can get sweat data without exerting yourself. The device uses a tiny electrical current (0.2mA) to send carbachol, a chemical found in eyedrops, into the upper layer of your skin. From there, it's just a matter of measuring the electrolytes concentrated in your sweat.
Jon Fingas08.06.2017A connected electrode could end the shame of sweaty palms
It's hard not to get sweaty walking around here at Computex in Taipei, but Tony Cueva Bravo had moist palms for another reason. The Peruvian entrepreneur suffers from hyperhidrosis, a condition that triggers excessive sweating, causing his hands to get frequently and uncomfortably moist. Hyperhidrosis can be off-putting and embarrassing, so Bravo did what any enterprising 24-year-old would do: He rounded up a team to find a fix and build a product to address it. Meet the Handrop, an orange-and-white potential game-changer that sits on your desk like a computer mouse.

Facebook Shouldn't Fact-Check Jessica Lessin, The New York Times How should Facebook combat fake news? The company isn't sure yet, but one tech journalist argues fact-checking isn't the answer. The Information's editor-in-chief Jessica Lessin penned an op-ed for The New York Times this week explaining why Facebook shouldn't take on the task of fact-checking news links that its users share on the site. From censorship to truth not always being black and white, this piece lays out why the social network allowing editors to decide what's newsworthy could impact privacy and journalism as a whole.

The Terminator may not feel remorse or pity, but does it even lift, bro? Researchers from the University of Tokyo have developed a robot called Kengoro that can sweat, helping it get through 11 minute push-up sessions that would normally fry the motors. Unlike a normal water-cooled radiator system, liquid flows into porous aluminum bones and then evaporates on the surface to cool the motors, in the same way that sweat cools a human.

What's the best way to promote a line of workout headphones? Well, if you're Urbanears, offering a "Limited Sweat Edition" that carries the perspiration of real human "movement makers" is how you go about it. The audio company teamed up with seven folks from fashion, music and sports on a group of sweat-soaked headphones that will be used to raise money for charity. Yes, it's pretty gross, but Urbanears is playing up the Hellas wireless headphones removable headband and earpads to remind you that said funk can be removed. And yes, you can buy a fresh pair if you prefer.

Kerry Davis01.28.2016Flexible sweat sensors monitor fluids while you exercise
Plenty of fitness wearables track fundamentals like your heart rate or step count, but there's so much more to your body than that. What about your fluid levels, for example? That's where UC Berkeley might help. It developed a flexible sensor that measures the electrolytes and metabolites in your sweat, along with your skin temperature. If you need to improve your diet, a quick run might reveal the truth.
Jon Fingas01.27.2016ISS astronauts mimic nature to turn urine into drinking water
Recycling water is key for astronauts on the International Space Station since sending water to the crew is heavy and expensive. The current systems work well and the tech is being used here on Earth in places where clean drinking water is in short supply. In an effort to increase efficiency, astronauts will test a new filtration system from Aquaporin Space Alliance. The so-called AquaMembrane employs nanotechnology and proteins to transform waste water (sweat and urine) into clean drinking water, proteins that regulate water in living things like human kidneys and bamboo shoots. Those aquaporin proteins are situated on a membrane and as water passes through tiny protein tubes, an electrostatic charge stops things like salt from getting through. The water flows continuously from side to side without using extra energy thanks to forward osmosis.
Billy Steele08.20.2015Scientists turn sweat into electricity with a temporary tattoo
What if running a 5K could do more than just burn calories? A team at the University of California San Diego have developed a temporary tattoo-like sensor that keeps tabs on exercise and converts sweat into electricity. The removable device monitors lactate: a substance that's present in perspiration and increases with more strenuous the activity. Athletes and some medical patients need to keep an eye on lactate levels for a range of reasons, but testing currently involves an invasive blood test during an exercise session. Here, an enzyme on the sensor collects electrons from lactate, and in turn, generates a modest electric current. What's more, the researchers turned those findings into a biobattery that's powered by the collected charge. The most energy produced by one person during the test was 70 microWatts per square centimeter of skin, but work is already underway to boost the system so that if can be used to power small gadgets like watches and heart-rate sensors.
Billy Steele08.13.2014Valve experiments with players' sweat response, eye-tracking controls for future game design
Valve has a surprisingly varied staff roster. Mike Ambinder is the company's very own experimental psychologist and he's been outlining some of Valve's work with biofeedback technology, including eye-motion controls for Portal 2 and perspiration-based gaming adjustments on Left 4 Dead. Mentioning these developments at the NeuroGaming Conference last week, Ambinder notes that both are still at an experimental stage, but that "there is potential on both sides of the equation, both for using physiological signals to quantify an emotion [and] what you can do when you incorporate physiological signals into the gameplay itself." In Left 4 Dead, test subjects had their sweat monitored, with values assigned to how much they were responding to the action. This data was fed back into the game, where designers attempted to modify (and improve) the experience. In a test where players had four minutes to shoot 100 enemies, calmer participants would progress normally, but if they got nervous, the game would speed up and they would have less time to shoot. When it came to the eye-tracking iteration of Portal 2, the new controls apparently worked well, but also necessitated separating aiming and viewpoint to ensure it worked. With Valve already involving itself in wearable computing, it should make both notions easier to accomplish if it decides to bring either experiment to fans. Venture Beat managed to record Ambinder's opening address at the conference -- we've added it after the break.
Mat Smith05.07.2013Thermaltake cures clamminess with $80 Cyclone Edition gaming mouse
Just when we needed a modern-day equivalent of sailing down the Nile while being fanned by Assyrian slaves, we get this: the Black Element Cyclone Edition gaming mouse, which has a 6,000 rpm rotor directed right at the point where slick skin meets plastic. Pictures of the device have been floating around the web for a while, but we've just heard from its creators -- TT eSports, Thermaltake's sub-brand for peripherals -- that it'll be available in US stores any day now (or officially, "in August") priced at $80. The patent pending design promises to keep noise down to a sub-environmental 21.7dB, while delivering an airflow of 2.6 cubic feet per minute -- which, if you're lucky, should be enough to not only keep your digits dry but also reach your palm. The fan can alternatively be removed, in which case you'll be left with a 6,500 dpi laser sensor, an adjustable weight of up to 22.5 grams, "military-grade" grip coating and an abundance of natural oils.
Sharif Sakr07.30.2012Epson joins fitness market with world's lightest GPS watch
In the world of electronics, the size of a device directly relates to its ability to pull ahead of the competition -- especially when it comes to fitness-tracking gadgets. The latest and greatest in this field has emerged from the most unexpected of places, with Epson, a company known for its printers and projectors, releasing the world's lightest GPS watch. This timepiece, specifically designed for runners, reportedly offers more accurate readings and better battery life (up to 12 hours on one charge) than competing products from Garmin, with acute data on distance, speed and pace, all due to its newly-designed 13mm-thick module. If sweat is an issue, the water-resistant casing offers protection against a full submersion of up to 50 meters -- you can wipe your brow with a sigh of relief. Pricing and availability on the company's latest concept is still unknown, but you can let your eyes do the jogging as you peruse the press release just past the break.
Joshua Tucker02.21.2012Scientists create sweat-monitoring underwear, break them in (video)
Biochip bracelets be damned -- nanoengineers at UC San Diego want to put sensors in your skivvies. Researchers have begun prototyping a pair of tighty-whiteys coated with the requisite carbon electrodes to make electrochemical computing a reality, as it turns out the nether regions are a prime place to measure chemicals excreted in one's sweat. Until recently, there was some question whether the enzyme sensor solution would handle the stresses of daily life, so to speak, but these briefs were up to the task -- subjected to a torturous gauntlet of bending and stretching, a treated elastic waistband was still able to adequately measure chemicals as required. Funded by the U.S. Office of Naval Research, project leaders envision "smart underwear" that measures a soldier's sweat for warning signs and automatically trigger an appropriate medical dosage. We think they might be getting a wee bit ahead of themselves, though -- we don't yet know how they handle detergent, let alone a quality color-safe bleach. Video after the break, but don't expect any footage of the underpants actually being worn.
Sean Hollister06.21.2010Your headphones' mic not working? Don't sweat it.
While I love the functionality of Apple's microphone-enabled headphones (both the Apple Earphones with Remote and Mic, which comes with the iPhone 3G S, and the iPhone Stereo Headset, which came with previous iPhones), I've found that the extra layers of functionality also bring extra layers of troubleshooting when they're not working right. For simplicity sake, I'll refer to said models as "iPhone headphones" in this post (non-volume control model pictured). The most common issues I've come across pertain to the microphone. Unlike most non-microphone enabled headphones, which use a standard two-ring TRS connector (tip, ring, sleeve), the iPhone adds an extra ring to support microphone functionality. This is what the hardcore audiophile refers to as TRRS (tip, ring, ring, sleeve). But if your pockets are consistently filled with lint and dust (or tater tots if you happen to store them there), that extra ring won't make full contact with the iPhone's headphone jack. Which means that you, unfortunately, will lose microphone functionality. One way to fix this is to remove any dust or lint trappings in the phone's jack. I've found that wrapping a toothpick with a thin layer of toilet paper and brushing it lightly against the walls of the headphone jack helps out a great deal. It's also important to not dip said toothpick in water or moisture. There's a moisture sensor in the iPhone's headphone jack. When exposed to moisture, it changes color and could potentially void your warranty. Also, the usual disclaimer in do-it-yourself scenarios apply: you're doing this at your own risk, so proceed with caution.

Alisha Karabinus09.28.2007Alexitimia robotic blob sweats when you touch it
Incorporating sweat sensors into gadgetry is nothing new, but an artist from Buenos Aires apparently felt that just detecting the liquid wasn't nearly good enough. The Alexitimia robotic blob was crafted by Paula Gaetano in order to showcase "creative intuition that permits both the artist and the viewer to leap over logic, whether scientific or artistic, and emotionally experience the problem laid out here of reconciling the wet domain of nature with the dry domain of electronics." Pretty far out, we know, but this creepy piece of blubber reportedly feels like rubber to the touch, and thanks to the integrated touch sensors, an internal water pump allows the pores to perspire in a zany attempt at showing affection. No word on whether this thing can blast out streams if your handling gets a little too rough for comfort, though.
