A coated article includes integrated circuit detection elements incorporated on a surface or embedded in a body, which elements are adapted to detect target chemical and/or target environmental conditions. The detection elements include microsensors applied with liquid and dry mixtures, including compounds of inks, dyes, print powders, aerosols and other suspensions. The microsensor state is detected and then processed to identify a detected value for the target chemical. Depending on the result, a readout substance is released to indicate a presence of the target chemical.
