Rollable Thin Film is Conductive and Transparent

Rollable Thin Film is Conductive and Transparent
A new ultra-thin, flexible material can be printed like a newspaper to create touchscreens that can be rolled into a tube.

The material was developed by a team led by researchers from RMIT, who used liquid metal chemistry to shrink a common thin film found in touchscreens from 3D to 2D. This liquid metal printing approach involves heating an indium-tin alloy to a liquid that can be rolled over a surface to create nano-thin sheets of indium tin oxide that are flexible, conductive and transparent. According to the team, the process is affordable and does not require specialized equipment, and could also improve smartphone displays and battery life.
