NEW DELHI, May 14, 2025 – In a groundbreaking development, researchers at the University of Southern California (USC) have introduced a wearable “smart” lactation sensor designed to protect infants from accidental overexposure to acetaminophen, a widely used painkiller. This innovative technology, integrated seamlessly into ordinary nursing pads, offers real-time monitoring of acetaminophen levels in breast milk, empowering mothers to make safer feeding decisions for their babies.
Addressing a Hidden Risk
Acetaminophen is commonly administered to mothers for postpartum pain relief and frequently given to infants to manage fever. However, this dual exposure-via both direct administration and breast milk-raises the risk of double dosing. Alarmingly, acetaminophen is the leading cause of acute liver failure in children and a primary reason for pediatric liver transplants in the United States.
For nursing infants, whose liver metabolism is still developing, even trace amounts of acetaminophen in breast milk can pose significant health risks. “Lactating mothers face unique health challenges, including the potential transfer of medications and other substances through their milk,” explained Dr. Maral Mousavi, Assistant Professor of Biomedical Engineering at USC.
How the Sensor Works
Traditional methods for detecting medication levels in breast milk are often expensive, complex, and inaccessible for everyday use. The USC research team tackled this challenge by enhancing a standard lactation pad with microfluidic channels that guide milk to a built-in sensing area. As milk naturally collects in the pad throughout the day, low-cost electrochemical sensors analyze its contents for acetaminophen and other health markers.
The sensor transmits real-time data to a user’s smartphone via a compact, portable detector-similar in function to a glucometer. This allows mothers to receive instant feedback on medication levels in their milk, enabling informed decisions such as choosing to pump and discard milk containing high levels of medication, thereby ensuring safer feeding practices.
Proven Accuracy
Researchers rigorously tested the sensor using human milk samples with varying acetaminophen concentrations. The device demonstrated reliable performance, accurately detecting the drug even in the presence of antibiotics and across different stages of breast milk composition, from colostrum to mature milk.
Looking Ahead
This innovation marks a significant step forward in child safety and maternal health, offering a practical solution to a previously under-addressed risk. With further development and adoption, such wearable sensors could become a standard tool for nursing mothers worldwide.
