摘要： A system and/or method for RF interrogation to read surface properties such as ultrasonic impedance and temperature in the field of measuring signals at a distance. The system includes a substrate with one or more piezoelectric transducers, at least one antenna connected to the substrate or formed onto the substrate, and one or more antenna terminals extending from the antenna and connected to terminals of at least one piezoelectric transducer. The antenna receives a radio frequency pulse and actuates at least one piezoelectric transducer. The piezoelectric transducer generates an ultrasonic pulse that reflects off a back side of the substrate. The reflected ultrasonic pulse is received at the piezoelectric transducer and drives the antenna that initially received the radio frequency pulse.
