Published Tuesday, January 9, A wearable device that tracks the heart rate and breathing of babies has been developed by University of Sussex scientists for parents concerned about the possibility of cot death. The technology uses liquid-based sensors which contain an emulsion made from graphene, water and oil, which conducts electricity. Comprised of carbon atoms, as a material graphene is strong, flexible and conductive, when a channel or tube holding the liquid is stretched, even by a small amount, the conductivity of the liquid changes.
Professor Alan Dalton of the University of Sussex said: They were inspired to create the health monitor after the Bill and Melinda Gates Foundation called for new affordable, wearable health technologies for babies in situations where resources are scarce. Currently, to monitor the pulses of babies clunky sensors need to be attached to their tiny hands or feet, and often fall off.
Due to the liquid technology being so sensitive, it picks up very small signals when attached to the body, the University of Sussex said. This means monitoring could be done wirelessly and non-invasively with a fitness tracker like band, or even embedded within the fabric of a sensor vest for a baby to wear.
He suggested the technology could one day even be expanded into fitness wear, and revealed he came up with the idea for the graphene emulsion as he was making a salad dressing with his daughter. It also means it should be affordable to individuals. Dr Matthew Large, lead researcher on the project, said the inclusion of graphene in the fluid stops the mixture of liquids separating over time.
