Scientists at the University of Southern California (USC) have unveiled a breakthrough wearable technology: a smart lactation pad that enables parents to monitor the safety of breast milk in real time. Published in the journal Device on May 7, 2025, the innovation is designed to address a critical gap in postpartum care by providing lactating individuals with actionable health insights about the breast milk they produce.
The smart pad is embedded with sensing technology that continuously analyzes samples of breast milk for specific substances, starting with the painkiller acetaminophen-commonly prescribed after childbirth and known to be transferred to breastfeeding infants. Acetaminophen, while generally safe at recommended doses, can pose serious risks if overexposed, including acute liver failure in children, making it the leading cause of drug-toxicity-related liver transplants in this age group.
The device works by detecting and measuring acetaminophen levels as the parent goes about daily routines, without requiring additional effort or sample collection. This real-time monitoring empowers parents to make informed decisions about breastfeeding and medication use, such as timing the “pump and dump” strategy to avoid feeding infants breast milk with elevated drug levels.
Currently, the smart pad is limited to analyzing milk produced through natural leakage, and each pad is disposable. The research team is developing a version that can test pumped milk, broadening its accessibility and convenience for parents.
Beyond acetaminophen, the technology can be adapted to monitor other drugs and biomarkers, such as glucose, offering potential benefits for managing conditions like gestational diabetes and supporting infant health monitoring.
