Non-invasive hormone monitoring with a wearable sweat biosensor

Nature Reviews Bioengineering volume 3, pages 190–191 (2025)Cite this article

Subjects

Wearable sweat biosensors enable the non-invasive, real-time monitoring of hormones. Here, we highlight the development and commercialization of a wearable technology that can measure hormone levels in sweat for women’s health applications, including fertility tracking and menopause management.
