NIST MEMS-based Rheometer (1 of 2) (VIDEO)

National Institute of Standards and Technology (NIST)

Caption

This is the NIST MEMS-based rheometer. The moving plate is controlled by resistance heating elements in the chevron-like structure at the top; expansion and contraction of the vanes causes the plate to move up and down. Central square where the sample would rest is approximately 500 micrometers across.
