NIST Invents Fleet and Fast Test for Nanomanufacturing Quality Control (2 of 2) (video) National Institute of Standards and Technology (NIST) Share Print E-Mail Loading video... Caption 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.
