Fitness performance wearable technology

We have developed a wearable device which provides real-time data analysis of fluid loss during exercise to enhance the performance of fitness enthusiasts and elite athletes.


Whether you’re a serious athlete or someone who likes to keep fit, it is important to make sure you get the right amount of fluid before, during and after exercising. Water regulates body temperature, lubricates joints and helps transport nutrients for energy and health. Inadequate hydration causes the body to under-perform and can lead to fatigue, muscle cramps, dizziness or more serious health symptoms.

While there are guidelines in place which help people understand how much they should drink, there's a demand for personalised information that will enhance overall performance and tailor hydration programmes. Heart monitors, pace-calculators and GPS-enabled watches are increasingly being adopted in sporting disciplines. Hydration monitoring is set to be the latest addition to the fitness market.


Our innovative transdermal sensor is a small device that attaches to the body to analyse electrolytes in sweat during physical activity.

Bluetooth technology is used to immediately send the data to a smartphone, computer or device – allowing the user to rehydrate properly and maintain optimum performance.

Wearing the sensor on skin does not cause any discomfort. During exercise the user is barely aware of its presence, allowing them to focus on their training without distraction.

The sensor will allow people to rehydrate optimally during and after exercise. Fitness coaches will also be able to monitor the data during competition to maintain performance. This could mean the difference between winning medals or going home empty handed.

The sensor has been developed in our Medical Diagnostics Research Group. The stringent application of medical device standards in our laboratory research means that the sensor will be qualified at the highest level for human use and translatable between sports science and medicine.

Following successful trials in Qatar and the UK, we're now keen to explore commercialisation opportunities.
