LadypHile pads represent a significant advancement in menstrual hygiene, combining innovative materials science with integrated health-monitoring technology. These pads are constructed from a composite of Polylactic Acid (PLA) and Chitosan, two biopolymers selected for their favorable properties in both environmental sustainability and functional performance. PLA, a biodegradable thermoplastic derived from renewable plant sources like corn starch, is utilized for its flexibility and degradability, ensuring that the product leaves a minimal environmental footprint. Chitosan, a polysaccharide derived from chitin (often found in shellfish), provides additional moisture-wicking, absorbent, and antimicrobial properties, enhancing the pad's ability to manage menstrual fluids while reducing bacterial growth on the surface.
 
A key innovation of the LadypHile pad is its dual-function health-monitoring system. Embedded within the pad is a pH-sensitive color-changing strip, which reacts to changes in vaginal pH levels. This provides immediate, non-invasive feedback on the user’s vaginal health. A shift in pH can signal the presence of bacterial vaginosis or yeast infections, offering a convenient means for early detection and proactive management of potential health issues. Additionally, the inclusion of a dried blood strip within the pad allows for the collection of a small blood sample during menstruation. This feature facilitates easy sample collection for further analysis, potentially enabling the monitoring of biomarkers related to menstrual health or systemic conditions.
