Abstract
A sensor device is disclosed, as well as methods and systems for determining a barrier property of each coating of an array of barrier coatings deposited onto a fluid-permeable or fluid-impermeable substrate. The systems and methods include the sensor device having a sensing layer responsive to a fluid of interest for which the barrier property of the array of coatings are desired to be determined. The sensor device further includes an overlayer disposed between the array of barrier coatings and the sensing layer. The overlayer protects the sensing layer from being damaged by the coatings.
