Graphene-Coated Rubber Bands Function as High-Strain Sensors

Aug-23-14 By coating rubber bands with graphene, researchers created an inexpensive motion sensor that could have a significant impact on health care.

The rubber-band sensors were developed by infusing normal rubber bands with graphene, transforming the elastic band into a high-performance sensor the team calls a 'G-band.' Besides being inexpensive to produce, the G-band has proven to be the most extensible strain sensor yet developed, which makes the band ideal for monitoring dynamic strain.

The material could also be particularly useful in patient monitoring, according to study author Professor Jonathan Coleman of Trinity College. “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 behaviors”
