Engineers creating miniaturized, wireless oxygen sensor for sick infants

Researchers are developing a sensor the size of a Band-Aid that will measure a baby's blood oxygen levels, a vital indication of the lungs' effectiveness and whether the baby's tissue is receiving adequate oxygen supply. Unlike current systems used in hospitals, this miniaturized wearable device will be flexible and stretchable, wireless, inexpensive, and mobile -- possibly allowing the child to leave the hospital and be monitored remotely.
