Abstract:
1. A system for measuring a physical measurand comprising: at least one variable impedance element probe responsive to at least one measurand; and at least one electromagnetic device (EMD) having at least one port, wherein said at least one variable impedance element probe is operably connected to said at least one port, said at least one EMD being electrically responsive to said response of said variable impedance element probe; wherein said at least one EMD is at least one acoustic wave device (AWD); wherein each of said at least one acoustic wave devices (AWDs) comprises an input port and at least one sensing port, wherein said at least one variable impedance element probe is operably connected to said at least one sensing port; wherein said at least one AWD is a reflective-tap delay line comprising reflective taps, wherein at least one of said reflective taps comprises at least one interdigital transducer (IDT), said IDT comprising said at least one sensing port; said system further comprising a plurality of said reflective taps providing an identification sequence specific to said system.
