Epicore Biosystems Launches Discovery Patch Sweat Collection System

PR Newswire

"Digital health solutions developer Epicore Biosystems has announced that it is launching its Discovery Patch® Sweat Collection System (“Discovery Patch System”). The platform consists of a wearable microfluidic patch that captures eccrine sweat directly from the skin during exercise, environmental exposure, and pharmacologic modes of sweat induction. Sweat is transferred from the microfluidic patch to clean lab storage containers using a sweat extraction apparatus designed to rapidly collect and prepare sweat samples for biochemical analysis."

'Sweat Sticker' Diagnoses Cystic Fibrosis on the Skin in Real Time

Northwestern University Engineering News

Epicore Biosystems, alongside a Northwestern Engineering-led research team has developed a novel skin-mounted sticker that absorbs sweat and then changes color to provide an accurate, easy-to-read diagnosis of cystic fibrosis within minutes. While measuring chloride levels in sweat to diagnose cystic fibrosis is standard, the soft, flexible, skin-like “sweat sticker” offers a stark contrast to current diagnostic technologies, which require a rigid, bulky, wrist-strapped device to collect sweat.

After developing the sweat sticker at Northwestern, the researchers validated it in clinical pilot studies involving cystic fibrosis patients and healthy volunteers at the Cystic Fibrosis Center at the Ann & Robert H. Lurie Children’s Hospital of Chicago. The sticker showed enhanced performance in collected sweat volume and equivalent accuracy to traditional platforms. The research and study findings were published March 31 as the cover feature article in the journal Science Translational Medicine.

Gatorade's Gx Sweat Patch delivers hydration, fitness guidance to athletes' phones

Mobi Health News

It's a concept that Gatorade first teased nearly five years ago before formally announced a partnership with Northwestern University and spinoff lab Epicore in 2018. Called the Gx Sweat Patch, the one-time use wearable is worn on the forearm during exercise to collect measurements and inform personalized fitness and nutrition recommendations. Gatorade is the latest to take a run at the connected fitness consumer. The PepsiCo brand launched today a sweat-tracking wearable patch and accompanying fitness monitoring app platform designed to help athletes track their workouts, hydration, salt concentration and other fitness-relevant metrics.

"The Gx Sweat Patch is the first of its kind soft, wearable, microfluidic patch," Roozbeh Ghaffari, CEO and cofounder of Epicore Biosystems and a research professor at Northwestern University's Biomedical Engineering Department.

Gatorade made a smart patch that measures your sweat and hydration


Alongside Epicore Biosystems, sports drink maker Gatorade is launching its first ever wearable device, the Gx Sweat Patch. The patch is a one-time-use wearable that analyzes sweat to provide athletes with insights about their athletic performance and hydration levels.

“Ultimately our goal is to bring the advanced science and services we provide elite athletes to anyone who’s looking to improve their performance,” said O’Brien. He says democratizing lab-based sweat testing allows everyday athletes to get one step closer to the pros.

New Flexible Skin Patch Can Help Track Your Health Through Sweat

VeryWell Health

Just a drop of sweat can reveal a lot about a person’s body. Now, understanding some key components of your biochemistry can be as easy as slapping on an adhesive patch and swiping it near your smartphone.

In a paper published this week in Proceedings of the National Academy of Sciences, a team of researchers announced the development of thin, flexible patches that can collect and analyze small quantities of sweat in real-time.

A Sweat Sensing Patch Aimed at Athletes Takes on COVID-19

IEEE Spectrum

Epicore Biosystems has been working on wearable sweat sensors for athletes. Now the startup aims to use the patches to fight the coronavirus pandemic

Epicore’s sweat-sensing technology may have several roles to play in the response to the coronavirus pandemic, including monitoring patients’ electrolyte levels and fatigue and non-invasively measuring their sweat cytokine levels. Physicians could use that information to predict cases in which COVID-19 will become life-threatening. And—if the technology were built into an N95 respirator mask—it could also track the health and fatigue of medical staff.

It’s Too Late to Undo Climate Change. We Need Tech in Order to Adapt

IEEE Spectrum

A raft of companies are developing tech to help us live in a warmer world.

One of the biggest risks in a warming world is that both outdoor workers and their equipment will overheat more often. Epicore Biosystems is building wearable microfluidic sensors that monitor people for dehydration or high body temperatures. The Epicore sensors are already being used for athletes. But it’s not hard to imagine that in the near future there’d be a market for putting them on construction, farm, and warehouse workers who have to perform outside jobs in hot weather.

Gatorade Gx Sweat Patch TV Commercial, 'Push the Game Forward' Featuring Jayson Tatum

Aired First on TNT

Best-in-class athletes like Jayson Tatum are always looking to push their game forward, Gatorade says, and that is where it comes in. The drink maker partnered with Epicore Biosystems to develop a first-of-its-kind wearable, the Gx Sweat Patch, which measures personalized sweat rate and composition. When athletes know what they sweat out, Gatorade says, they better know what to put back in.
