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 widely used due to their complexity and cost of production. Now researchers from the University of Surrey and Trinity College Dublin have for the first time treated 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 easily made. 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.

Take me to the complete story . . .
