Duco is the world’s first wearable device for continuous, needle-free hormone monitoring. Worn on the upper arm, it analyses sweat to track hormone levels in real time, using colourimetric analysis and a microfluidic sensor. Results are displayed on a smartphone and can be shared with doctors for remote care. Initially targeting conditions like Addison’s Disease and hormone imbalances, Duco aims to transform chronic condition management, offering patients a reusable, non-invasive alternative to traditional blood tests
