Abstract
A wireless sensor is disclosed, which includes a substrate upon which the wireless sensor can be configured. The wireless sensor includes a plurality of surface acoustic wave (SAW) sensing elements configured in parallel with one another upon the substrate, wherein one or more of the SAW sensing elements is responsive to a wireless frequency range that differs from that of a wireless frequency range of at least one other SAW sensing element among the group of SAW sensing elements. It is this parallelism that permits all of the SAW sensing elements to receive the same strain when pressure is applied thereon. In doing so, the capability for three separate interrogators to measure strain is provided. At any one location, however, only one style of interrogators can be employed, rendering two of the three SAW sensing elements useless, without interfering with the one SAW sensing element that is useful in order to permit a wireless interrogation of the wireless sensor despite varying international frequency standards thereof.
