Researchers at the University of Sussex have developed a graphene-based sensor with the potential to prevent sudden infant death syndrome (SIDS) cases. The sensor is shaped like a flexible rubber tube filled with a solution of water, oil and particles graphene.
the sensors were said to be the most sensitive liquid-based devices to have ever been developed. Utilizing graphene's conductivity, the solution inside the tube conducts electricity. When the tube is stretched by even a tiny amount, the conductivity also changes and this change can be detected, indicating that movement (such as the rising and falling of a breathing person's chest) is occurring.
