This invention integrates a diagnostic recognition layer into women’s daily sanitary pads, transforming a routine product into a discreet health monitoring system. The pad collects vaginal fluids such as discharge, menstrual blood, and secretions, which interact with embedded chemical indicators to detect parameters like pH, infection markers, amniotic fluid leakage, ovulation, and sexually transmitted diseases. Colorimetric changes on the recognition layer are captured using a smartphone camera and analyzed through image processing algorithms. The results are converted into digital health data and delivered to the user via a mobile application, enabling continuous, non-invasive monitoring without clinical intervention. This approach combines the familiarity of a daily-use product with advanced diagnostic technology, providing women with accessible, real-time insights into their reproductive and overall health.
