Development of Novel Non-Contact Sampling Tools and Techniques

Summary

We are investigating non-contact methods for high volume, high throughput, and high transfer/transport efficiency screening and documenting appropriate testing standards and protocols. Using NIST expertise in basic metrology, standards, microscopy, fluid mechanics and flow visualization, high speed videography, and computation fluid dynamics, NIST can identify limitations in new technologies and provide potential solutions early in the development cycles of next-generation equipment. This work includes the development of the first artificial dog nose.
