NANO-POROUS ALUMINA HUMIDITY SENSORS
Journal Title: Metrology and Measurement Systems - Year 2008, Vol 15, Issue 2
Abstract
In this paper the details of porous alumina humidity sensors fabricated using anodic aluminium oxidation are presented. The main aim of this study is to establish relations between technological process parameters and electrical properties of sensors. Surface morphology was investigated by scanning electron microscopy. Impedance spectroscopy was used to identify electrical parameters of the sensor

DETERMINING THE UNCERTAINTY OF FITTING DISCRETE MEASUREMENT DATA TO A NOMINAL SURFACE
Coordinate measurements are a source of digital data in the form of coordinates of measurement points with a discrete distribution on the measured surface. Geometric deviations of freeform surfaces are determined at each...
