#Graphene rubber bands could stretch limits of current healthcare New research published today in the journal ACS Nano identifies a new type of sensor that can monitor body movements and could help revolutionise healthcare. Although body motion sensors already exist in different forms they have not been used widely due to their complexity and cost of production. Now researchers from the University of Surrey and Trinity college Dublin have treated for the first time common elastic bands with graphene to create a flexible sensor that is sensitive enough for medical use and can be made cheaply. Once treated the rubber bands remain highly pliable. By fusing this material with graphene -which imparts an electromechanical response on movement the team discovered that the material can be used as a sensor to measure a patient's breathing heart rate or movement alerting doctors to any irregularities. Until now no such sensor has been produced that meets needs and that can be made easily. It sounds like a simple concept but our graphene-infused rubber bands could really help to revolutionise remote healthcare said Dr Alan Dalton from the University of Surrey. Co-author Professor Jonathan Coleman from Trinity college Dublin commented This stretchy material senses motion such as breathing pulse and joint movement and could be used to create lightweight sensor suits for vulnerable patients such as premature babies making it possible to remotely monitor their subtle movements and alert a doctor to any worrying behaviours. These sensors are compared extraordinarily cheap to existing technologies. Each device would probably cost pennies instead of pounds making it ideal technology for use in developing countries where there are not enough medically trained staff to effectively monitor and treat patients quickly.
