Previewed at TED: Microfluidics sweat analysis from Gatorade


The old adage decrees it takes ‘blood, sweat and tears’ to be the best in your athletic field. But Epicore Biosystems reckons one of those fabled fluids is much more important than the others – and the start-up has developed a patch to capture and analyse your sweat.

It has developed wearable technology to capture sweat, analyse the unique biomarkers within it and offer custom hydration recommendations based on it. The goal is to ensure athletes are drinking enough fluids – and the right kinds of fluids – at half-time to maintain peak levels throughout the game.

Inside the Lab Where Gatorade Is Transforming Itself Into a Tech Company


When you think of Gatorade, you probably picture a neon orange or yellow sports drink. But the company is trying to carve out a niche for itself in another increasingly important aspect of fitness: technology.

Or, more specifically, technology that measures your sweat. Gatorade's sweat patch--which it's currently testing at its Sports Science Institute in Bradenton, Florida, and hopes to roll out to consumers next year--can be worn by athletes during practice or workouts to help them track hydration and nutrients they've lost through perspiration. Xavi Cortadellas, Gatorade's head of innovation and design, says that information will help them refuel more effectively, which, in theory, should provide them with an extra edge on the field. It's a key part of the company's plans for providing athletes with access to comprehensive information about their performance.

Previewed at TED: Microfluidics sweat analysis from Gatorade


Imagine if, after your next workout, you could see not only how much you sweat, but what you sweat — and how to replenish what’s missing. That’s the promise of a new sweat analysis patch from Gatorade, shown in preview form at TED2019.

How it works: You place the small, flexible patch on your arm before a workout. Then the microfluidics inside the patch get to work.

An Underwater Skin Sensor Lets Swimmers Track Their Sweat


SPORTS TEAMS COLLECT sweat to analyze athlete performance, while companies market sweat replacement drinks and sweat-removal clothing to help keep sprinters, cyclists, and tennis players happy. But so far, swimmers have been left high and dry.

Today a team of researchers announced they have built a small, flexible, wireless sensor that sticks to a swimmer’s skin, allowing athletes to measure how much they need to drink during a workout or race. The device picks up sweat secretions from a person’s skin and channels the fluid into a chemical reagent mixed with food dye. It then turns the patch different colors corresponding to a person’s chloride levels—much like a pH strip for sweat. It also measures body temperature and sweat loss rate.

Your Sweat Will See You Now

New York Times

A new generation of devices instead aim to analyze sweat for many chemicals at once, producing a real-time snapshot of the wearer’s health or fitness. These devices also fit intimately against the skin, and are comfortable for anyone, from premature babies to the elderly. One version is already being advertised by Gatorade.

Serena Williams talks about her new tech-infused Gatorade ad

Fast Company

Back in late 2015, Gatorade was developing a new system of products to help athletes evaluate, measure, and replace the types of electrolytes their bodies need most. Measurement was done by a bandage-like patch that monitors sweat rate and type, while a variety of small pods that differed in electrolyte type could be mixed with water in specially designed sport bottles. All this was designed to give athletes the best possible advantage through the most efficient hydration. Now three years later, Serena Williams is rocking the patch and pod combo in a new ad campaign called “You Fuel Us, We Fuel You.”

LEO Science & Tech Hub Partners with Epicore Biosystems to Explore Wearable Skin Sensors to Improve Dermatologic Treatment Regimens

Business Wire

CAMBRIDGE, Mass.--(BUSINESS WIRE)--LEO Science & Tech Hub, the Boston-based R&D innovation unit of LEO Pharma, has announced a new partnership with Epicore Biosystems focused on exploring the use of a non-invasive, wearable sweat sensor to measure prognostic biomarkers in real time, monitor patient response and inform treatment decisions. The initial project will include a proof of concept study in collaboration with engineers and dermatologists at Northwestern University’s Center for Bio-Integrated Electronics and Feinberg School of Medicine’s Department of Dermatology to establish baseline measurements and milestones to validate the clinical relevance of the approach for patients with atopic dermatitis (eczema).

Gatorade, Northwestern University partner on sweat-reading hydration patch

mobihealth news

Gatorade’s efforts to conquer dehydration have again entered the digital realm. Twice reports that the sports drink company and Northwestern University have developed a low-cost wearable skin patch that displays various colors to conveniently let the wearer know when they need to take a drink.

The patches were developed and introduced in 2016 by Northwestern University McCormick School of Engineering professor John A. Rogers, who told Twice that the devices could make their way to retail within a year, and potentially at a price point of just $3. These patches, which were also profiled last month by Northwestern University’s communications publication, Northwestern Now, can measure chloride loss, glucose, lactate, pH levels, and concentrations of heavy metals in the wearer’s sweat.

Skin-interfaced systems for sweat collection and analytics

Science Advances

Recent interdisciplinary advances in materials, mechanics, and microsystem designs for biocompatible electronics, soft microfluidics, and electrochemical biosensors establish the foundations for emerging classes of thin, skin-interfaced platforms capable of capturing, storing, and performing quantitative, spatiotemporal measurements of sweat chemistry, instantaneous local sweat rate, and total sweat loss. This review summarizes scientific and technical progress in this area and highlights the implications in real time and ambulatory modes of deployment during physical activities across a broad range of contexts in clinical health, physiology research, fitness/wellness, and athletic performance.

Super-Absorbent Polymer Valves and Colorimetric Chemistries for Time-Sequenced Discrete Sampling and Chloride Analysis of Sweat via Skin-Mounted Soft Microfluidics

Small Journal

This paper introduces super absorbent polymer valves and colorimetric sensing reagents as enabling components of soft, skin-mounted microfluidic devices designed to capture, store, and chemically analyze sweat released from eccrine glands. The valving technology enables robust means for guiding the flow of sweat from an inlet location into a collection of isolated reservoirs, in a well-defined sequence.
