Researchers from the Graphene Flagship at TU Delft 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.
In this simulation, requested by Santiago Cartamil and performed by Scixel, graphene changes its colour depending on its own deformation. These pixels, which do not emit light themselves but are visible in sunlight, could lead to energy-efficient colour displays that can be used in devices such as e-books and smart watches.
Are we witnessing a change of paradigm?
