A fast response pressure-sensitive dot array sensor has been developed by means of an inkjet printing technique on an anodized aluminum substrate, which has been used for unsteady flow measurements. However, PtTFPP based dot array sensor has several problems: non-uniform distribution of luminescent intensity due to "coffee ring effect" and low luminescent intensity. To solve these problems, we fabricated the PtTFPP-based dot array sensor on an anodized aluminum substrate with hydrophobic treatment. The hydrophobic treatment was applied to an anodized aluminum in three ways: dipping in the solution of dodecanoic acid in hexadecane, dipping in the solution of dodecanoic acid in water, and spraying the fluorine hydrophobic coat. The effect of the three hydrophobic treatments on the characteristics of PSP dots was investigated.
