Muun Health, the Estonia-based company developing a wearable device for continuous female hormone monitoring, has secured a €700K grant from Enterprise Estonia to develop its Smart Patch Platform. The grant is part of a €1 million project focused on advancing the sensor’s bioselective layer to enable real-time hormone measurement from interstitial fluid.

Muun Health is developing a wearable patch that measures female sex hormones multiple times per day, providing real-time insights into ovulation and reproductive health through a mobile app. The device is positioned as an alternative to traditional methods like urine strips or blood tests, transmitting data directly to a smartphone.

“Muun Health is on a mission to advance women’s health quality with a novel continuous hormone monitor that gives both women and clinicians actionable data to make timely, informed decisions,” the company said.

The grant follows Muun Health’s €545K pre-seed round in late 2025 from Greiner Innoventures and The Better Fund Community Business Angels. Founded in 2023 by Kerli Luks, the company joins a growing cohort of players building toward continuous hormone monitoring – a category that has attracted significant activity recently
