World's First Wearable Device to Measure Neonatal Jaundice and Vitals


World’s First Wearable Device to Measure Neonatal Jaundice and Vitals

Treatment for jaundice can be done effortlessly by irradiating the infant with a blue light that disintegrates bilirubin, which is later secreted via urine. But the treatment itself can disturb bonding time, lead to dehydration and elevate the risks of allergic diseases. ....

First wearable device can monitor jaundice-causing bilirubin and vitals in newborns

Researchers in Japan have developed the first wearable devices to precisely monitor jaundice, a yellowing of the skin caused by elevated bilirubin levels in the blood that can cause severe medical conditions in newborns. Jaundice can be treated easily by irradiating the infant with blue light that breaks bilirubin down to be excreted through urine. The treatment itself, however, can disrupt bonding time, cause dehydration and increase the risks of allergic diseases. Neonatal jaundice is one of the leading causes of death and brain damage in infants in low- and middle-income countries.
To address the tricky balance of administering the precise amount of blue light needed to counteract the exact levels of bilirubin, researchers have developed the first wearable sensor for newborns that is capable of continuously measuring bilirubin. In addition to bilirubin detection, the device can simultaneously detect pulse rate and blood oxygen satur ....
