Pressure is one of the most frequently measured physical quantities. For this reason, it is useful to have pressure sensors that adapt to the most varied applications. Here a simple wireless pressure sensor based on a mm-wave chipless RFID tag is proposed. The tag is composed of an artificial impedance surface loaded with a superstrate. The combination of the periodic surface with the superstrate results in a frequency shift of the resonant peak when pressure is applied to the tag.

Abstract
Pressure is one of the most frequently measured physical quantities. For this reason, it is useful to have pressure sensors that adapt to the most varied applications. Here a simple wireless pressure sensor based on a mm-wave chipless RFID tag is proposed. The tag is composed of an artificial impedance surface loaded with a superstrate. The combination of the periodic surface with the superstrate results in a frequency shift of the resonant peak when pressure is applied to the tag.File in questo prodotto:
