Transcript text: Sometimes babies are born a little early. When this happens, skin sensors are used to monitor a baby's vital signs, such as temperature, pulse, and breathing rate. The trouble with skin sensors is they attach to the skin and can be uncomfortable. Researchers have developed a new system that doesn't make contact with the baby. Instead, it uses wireless cameras to monitor vital signs. Another issue with skin sensors is they're often inaccurate; a baby's slight movements can set them off. The cameras in the new system are highly sensitive, however. They detect the newborn's pulse by analyzing skin color, which changes slightly with every heartbeat. Even at night, babies need to be monitored. The new system deals with low light by using infrared cameras, which use heat instead of light to create images.
