Abstract
This paper presents a novel combined PSP・TSP sensor, which is composed of arrays of tiny PSP and TSP dots. We fabricated the combined sensor, dual-array sensor, by inkjet-printing of PSP and TSP solutions. The dual-array sensor is unique among combined PSP・TSP sensors in the point that PSP and TSP luminophores are discretely arranged on a measurement surface. This prevents interactions between PSP and TSP luminophores that has been one of major issues in conventional combined sensors, and makes it possible to select optimal binding material and solvent for each luminophore. From emission spectrum, pressure and temperature sensitivities of a fabricated dual-array sensor, the dual-array sensor is able to combine any luminophores without paying attention to the interaction issues. Moreover, a demonstration shows that the dual-array sensor is a favorable pressure sensor for the measurements on surfaces with non-uniform temperature distribution.
