The team put a single graphene sheet between two layers of polymer and used Raman spectroscopy to measure how the carbon bonds responded when the graphene was stretched.

In 2002 IBM unveiled Millipede, a kind of computer memory that promises to store hundreds of gigabytes of data per square centimetre by punching nanoscale holes in a polymersheet.
The pixels are then built into displays by embedding them and their electrical connections in a sheet of another polymer, this time a transparent and flexible one.
