According to Japan's Yokohama National University, jaundice occurs in 60 to 80 percent of all newborn babies, and can result in brain damage or even death if left unchecked. That's why they've developed a new wearable device to help in its treatment.
Jaundice is caused by an elevation of bloodstream levels of a compound known as bilirubin, which causes the skin to turn yellow. Treatment typically involves exposing the infant to blue light, which breaks the bilirubin down so it can be passed with the urine. That said, the process takes away from time in which the infant could be bonding with its mother, plus it can lead to dehydration and the development of allergies.
Currently, pediatricians periodically assess bilirubin levels in jaundiced babies via a handheld tool known appropriately enough as a bilirubinometer. Led by Assoc. Prof. Hiroki Ota, a team of Yokohama scientists set out to develop a device that performs the same task continuously.
