How Wearable Patches Are Tracking Hydration for Endurance Athletes

Episode 89 of The Wearable Tech Podcast explores an emerging category in health wearables: hydration patches. Lucas and Luna examine how a company called Nix Biosensors developed a single-use adhesive patch that analyzes sweat in real time to measure electrolyte loss and fluid balance. The patch, which costs about $20 per use, streams data to an athlete's phone or watch, allowing marathon runners and cyclists to customize their hydration strategy mid-race. The hosts discuss the technology behind the patch—microfluidic channels and ion-selective electrodes—and compare it to older methods like pre- and post-race weigh-ins. They also touch on the challenge of persuading recreational athletes to adopt a consumable wearable that costs more per race than their last pair of running socks.
