The cantilever based devices relying on optical beam steering, even though sensitive as sensors, have rather limited penetration to the market. The obstacle that has prevented so far the wider spread of such devices is the inability to monolithically integrate the photonic components on the same die with the cantilever. In this work, a novel microsystem is presented comprising integrated Si light...
A highly sensitive alternative to established methods for measuring oxygen transmission rates of ultra-barrier membranes is presented. The key idea is the employment of an opto-chemical sensor (a luminescent dye immobilized in a matrix) which has vital advantages over electrochemical sensors, such as consumption-less detection and extraordinary sensitivity. The luminescent response to modulated light,...
