Placeholder. Real academic labs have already built diapers that can detect early signs of UTIs and other biomarkers via embedded RFID and electrochemical sensors — years ahead of anything on shelves — while the one commercial smart-diaper product that did ship (Pampers Lumi) was quietly discontinued.
What we've found so far: A*STAR (Singapore) published peer-reviewed RFID/electrochemical UTI-detection diaper research; Pampers Lumi (Bluetooth wetness sensor) launched 2019 and was later discontinued.
