40465 2017 eng lecture 0 -- -- -- The talk addresses layer-based sensors for monitoring applications. In particular, sensor principles surface plasmon resonance (SPR), air-coupled ultrasonic, and magneto-optical coupling are discussed. Optical sensors on planar substrates are prepared by sol-gel, CVD- and PVD deposition techniques, ultrasonic sensors on planar and curved substrates are made by means of PVD processes, and magnetostrictive coatings for magneto-optical sensors are deposited on fibre-based Bragg gratings (FBGs) using PVD and ECD techniques. For all kinds of sensors design and function are explained and discussed, i.e. regarding sensitivity. It is shown that a) SPR enhanced ellipsometry is a promising tool for gas monitoring of hazardous gases, that b) thermos-acoustic and piezo-electric pulse-echo techniques are relevant for damage inspection of hidden volume defects of CFRPs, and that c) magnetostrictive-optical sensors with self-calibrating (magnetic reference field) function are useful for structural health monitoring in terms of strain sensors.
