Claim 11:
12. A method for wireless sensing environmental conditions, the steps comprising:
harvesting an interrogation energy with a smart sticker, the smart sticker having an RFID loop antenna and at least one sensor, wherein the interrogation energy is transmitted by a reader device;
inducing a current in the at least one sensors;
based on the induced current, measuring an environment condition with the at least one sensor, wherein one of the at least one sensors is a conductive ink trace further comprising 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; and
backscattering the environmental condition measurement to the reader device.
