Epicore Biosystems is an American wearable technology company that analyses sweat. It develops soft skin patches and connected systems for industrial safety, sports hydration and clinical research. Its products show how much fluid and salt a person loses during heat or activity.

How it works
Microfluidic channels collect sweat as it leaves the skin. Sensors or colour changing markers measure sweat volume and chloride concentration, while connected products add skin temperature and movement. Software estimates fluid and electrolyte loss, then presents guidance to the wearer or an organisation. Research patches can preserve samples for laboratory analysis.

Key considerations
Epicore serves organisations, researchers and athletes, so access and features depend on the product and programme. Sweat composition varies by body location, activity and environment. Single use patches create recurring supply needs.
