Liquid Electronics: Wrapping droplets in graphene for printed microchips and wearable sensors

Graphene-wrapped emulsion droplets deposited onto electrodes for single-droplet thin-film electronic devices

New research from physicists at the University of Sussex will ‘significantly advance’ the new technology area of liquid electronics, enhancing the functionality and sustainability of potential applications in printed electronics, wearable health monitors and even batteries.

In their research paper published in ACS Nano, the Sussex scientists have built on their previous work to wrap emulsion droplets with graphene and other 2D materials by reducing the coatings down to atomically-thin nanosheet layers. In doing so they were able to create electrically-conducting liquid emulsions that are the lowest-loading graphene networks ever reported — just 0.001 vol%.

This means that ...
