A groundbreaking new device may soon change the way newborns are monitored in neonatal intensive care units (NICUs). Researchers at the Georgia Institute of Technology have developed a wireless pacifier that continuously tracks a baby’s electrolyte levels, potentially eliminating the need for repeated, painful blood draws.
A Solution to a Persistent Problem
Newborns in the NICU require frequent vital sign monitoring, and one of the most critical indicators of health is electrolyte balance. Currently, the only way to check electrolyte levels is through multiple daily blood draws. This process can be distressing for the infant and challenging for medical staff due to the difficulty of drawing blood from tiny, underdeveloped veins.
Hong Yeo, associate professor and Harris Saunders Jr. Endowed Professor in the George W. Woodruff School of Mechanical Engineering, conceived the idea for the pacifier at a pediatric technology conference. After hearing about the struggles doctors face in monitoring newborns, he sought to create a noninvasive alternative.
“I wanted to come up with a noninvasive solution for constant electrolyte monitoring, and I decided to focus on something babies like: pacifiers,” Yeo said. “I immediately thought, ‘OK, I can do something with that.’”
How It Works
Yeo and his team modified commercially available pacifiers, integrating microfluidic channels to collect saliva. The pacifier draws saliva into a reservoir equipped with ion-detecting sensors that continuously measure sodium and potassium levels.
To ensure seamless operation, Hojoong Kim, a research professor at the Wearable Intelligent Systems and Healthcare (WISH) Center, developed an ultrathin, membrane-based electronic circuit. The circuit, placed on the back of the pacifier, enables wireless data transmission via Bluetooth. This allows physicians to monitor electrolyte levels in real time using a smartphone or tablet, providing continuous updates on a baby’s health.
This uninterrupted flow of data offers a more comprehensive picture of the infant’s condition, allowing medical staff to detect potential complications early and respond more quickly.
The Future of Pediatric Health Monitoring
The research team continues to refine the pacifier and is actively seeking funding and commercialization partners. According to Yeo, this innovation could significantly enhance neonatal care. “Once we get it into hospitals, I think the device will be a game-changer for pediatric health monitoring,” he said.
Beyond newborns, researchers believe the technology could be adapted for other patients by using saliva to monitor various biomarkers for different medical conditions.
“This is an important step in showing that this technology can work,” Yeo added. “We hope to integrate the technology with other electrical sensors and systems to achieve comprehensive health monitoring that wasn’t possible until now.”
