Abstract:
A radiofrequency transceiver is used for the dual purpose of probing surface acoustic wave resonator sensors and communicating the resulting measurements through a digital wireless link. Thus, the radiofrequency hardware exhibits a complementary use of short range probing of piezoelectric sensors subject to harsh environmental conditions, and long range digital communication through a wireless sensor network. The demonstration is performed in the 434 MHz European Industrial, Scientific and Medical band, yielding half-duplex communication ranges well beyond 100 m.
