Functional Metrology

Definition

Functional metrology is the science of measurement that focuses on evaluating and quantifying the functional performance of devices, particularly at the nanoscale. This concept is crucial for ensuring that nanofluidic devices operate as intended, meeting specific performance criteria such as fluid flow rates, pressure, and thermal properties. By using precise measurement techniques, functional metrology helps standardize the manufacturing and testing processes of these devices to ensure reliability and consistency in their applications.
