Measurements of electrical properties of a plastic tape (yellow), taken using a specially designed microwave cavity (the white cylinder at center) and accompanying electrical circuit, change quickly and consistently in response to changes in the tape's thickness. The setup is inspired by high-volume roll-to-roll manufacturing devices used to mass-produce nanomaterials. The changes in the tape's thickness spell NIST in Morse code.
NIST Invents Nanomanufacturing Test
If carbon nanotubes and graphene are going to play an increasingly important role in applications, manufacturers will need quality-control tests to ensure that products lack flaws.
