Graphene Balloons Show Their Colors

Researchers from the Graphene Flagship have found a new potential application for graphene: mechanical pixels. By applying a pressure difference across graphene membranes, the perceived color of the graphene can be shifted continuously from red to blue. This effect could be exploited for use as colored pixels in e-readers and other low-powered screens. The research was a collaborative effort from researchers at TU Delft, Netherlands, and Graphenea, Spain, and the study has recently been published in the journal Nano Letters.
