The device, which uses light shone through a child's skin, should be able to check a heart rate quicker and more reliably than a traditional stethoscope.

A small optical probe, when placed on the baby's head, will monitor the heart rate autonomously by measuring changes in blood flow under the skin and therefore detect the baby's pulse.A small optical probe, when placed on the baby's head, will monitor the heart rate autonomously by measuring changes in blood flow under the skin and therefore detect the baby's pulse.
