Claim 10:
11. A smart sticker system, comprising:
a radio frequency identification tag comprising a chip and a loop antenna, the loop antenna being configured to backscatter sensor information to an external reader; a plurality of sensors configured to provide environmental data, each of the sensors further comprising:
a substrate having a proximal side and a distal side, wherein the proximal side of the substrate s mounted to the chip;
a conductive ink trace disposed on the distal side of the substrate, wherein the conductive ink trace comprises a plurality of resistors configured to measure corrosion, and wherein each resistor has a unique width and collectively operate to determine a rate of corrosion;
a resin fully enveloping the radio frequency identification tag and partially enveloping the distal side of the substrate; and
a reader device configured to collect environmental data.
