2025: Continuous lactate monitor (LactlQ) (completed)

We aim to develop a wearable, patch‐based lactate sensor that continuously monitors interstitial lactate levels without painful blood sampling and disposable strips, or interrupting training flow.

Project description

Building on the success of continuous glucose monitors, our device will embed lactate‐oxidizing enzymes (e.g., lactate oxidase) within a microneedle array to catalyze lactate in dermal interstitial fluid into pyruvate and hydrogen peroxide. An integrated electrode will then oxidize the generated hydrogen peroxide, producing electrons whose current correlates directly with lactate concentration. By tracking these electrical signals in real time, athletes can optimize training and recovery on the fly while reducing recurring costs and biological waste. The market potential is also significant, not only to athletes in Norway but has a broader appeal to European athletes and sport enthusiasts as well. The Continuous Lactate Monitor (CLM) has already gained strong endorsements from elite coaches and institutions like Olympiatoppen, NIH (Norwegian School of Sport Sciences).  Over the summer, we will express and immobilize the enzyme, prototype the microneedle–electrode interface, and validate sensor performance in laboratory conditions, laying the groundwork for a low‐cost, sustainable sports biosensor. Wearable fitness technology continues growing rapidly, and our goal is to develop a device to empower athletes to push just right and reach new heights, through data-driven training.
