Abstract: In an embodiment, a multilayer structure can comprise: an outermost layer; a sensor; a multilayer substrate A located between the sensor and the outermost layer, the multilayer substrate, comprising greater than or equal to 16 polymer A layers, preferably 16 to 512 polymer A layers; and greater than or equal to 16 polymer B layers, preferably 16 to 512 polymer B layers; wherein the polymer A layers and the polymer B layers are present in a ratio of 1:4 to 4:1, preferably the ratio is 1:1; wherein the multilayer substrate has a transmission of greater than or equal to 70%, preferably greater than or equal to 75%, or greater than or equal to 80%; wherein the structure has a water vapor transmission rate of less than or equal to 10 g/cc/day, preferably less than or equal to 8 g/cc/day, or less than or equal to 5 g/cc/day, or less than or equal to 2 g/cc/day.
