A novel combined Pressure-/Temperature-Sensitive Paint (PSP/TSP) sensor, which consists of dot arrays of PSP and TSP, has been developed for simultaneous measurements of pressure and temperature on a solid surface. Conventional combined PSP/TSP sensors suffer from the photodegradation caused by interaction between PSP and TSP luminophores. In the proposed sensor, dot arrays of PSP and TSP were separately arranged for avoiding the interaction. The PSP and TSP dots were made of PtTFPP and CdSe/ZnS, respectively, so that the luminescences from each dot array could be separately detected by optical filters. We investigated fundamental properties of the dot array sensor: photostability, pressure sensitivity and temperature sensitivity. As a result, the photodegradation was not observed in the dot array sensor. It was also shown that PtTFPP dot array had the pressure sensitivity of 0.53%/kPa, and CdSe/ZnS dot array had the temperature sensitivity of -0.61%/K, which were almost the same sensitivities as conventional PSPs and TSPs. Therefore, the proposed sensor will be a preferable sensor for the simultaneous measurement of pressure and temperature.
