阳极氧化铝压敏涂料（AA-PSP）已被用作非定常流量测量的全局压力传感器。我们采用浸镀法在多孔阳极铝表面涂敷发光团，通过控制浸镀法的发光团浓度来优化AA-PSP特性。浓度从0.001到10mm不等。表征包括压力敏感性、温度依赖性和信号水平。在0.1 mM以下的较低浓度下，压力灵敏度约为60%。超过此浓度，灵敏度降低到一半。通过将发光团浓度设置为0.001至10 mM，温度依赖性变为一半以上。通过改变浓度，信号电平变化3.6倍。为了讨论最佳浓度，引入了一个权重系数。我们可以任意改变系数来创建一个优化的AA-PSP用于我们的传感目的。
Anodized-aluminum pressure-sensitive paint (AA-PSP) has been used as a global pressure sensor for unsteady flow measurements. We use a dipping deposition method to apply a luminophore on a porous anodized-aluminum surface, controlling the luminophore concentration of the dipping method to optimize AA-PSP characteristics. The concentration is varied from 0.001 to 10 mM. Characterizations include the pressure sensitivity, the temperature dependency, and the signal level. The pressure sensitivity shows around 60 % at a lower concentration up to 0.1 mM. Above this concentration, the sensitivity reduces to a half. The temperature dependency becomes more than a half by setting the luminophore concentration from 0.001 to 10 mM. There is 3.6-fold change in the signal level by varying the concentration. To discuss an optimum concentration, a weight coefficient is introduced. We can arbitrarily change the coefficients to create an optimized AA-PSP for our sensing purposes.
