8. A wireless corrosion system, comprising:
-
a processor; a transceiver device coupled to the processor; and a corrosion detector including at least one electro-resistive (ER) sensor coupled to an output port of a surface acoustic wave (SAW) sensor tag, wherein; the SAW sensor tag is interrogated by a radio frequency (RF) signal generated by the transceiver, the SAW sensor tag rebroadcasts a response RF signal incorporating amplitude variation and delay, and the response RF signal is received by the transceiver and interpreted by the processor as corrosive activity. - View Dependent Claims (9, 10, 11, 12, 13, 14)
