Researchers have developed a pacifier designed to monitor a baby’s electrolyte levels in real time, potentially eliminating the need for repeated invasive blood draws. The team constructed a tiny tunnel, or microfluidic channel, into the body of the pacifier.

The opening at the pacifier’s nipple draws saliva into the channel, which then guides the saliva through the device and into a reservoir equipped with ion-detecting sensors. The sensors react to sodium and potassium ions, constantly measuring their levels.

The team installed their flexible circuit on the back side of the pacifier. There, they integrated all the circuit’s wireless components to be compatible with conventional Bluetooth. The system sends the data wirelessly, so physicians can use a smartphone or tablet to receive a real-time, continuous flow of data about a baby’s vitals at any given moment.
