    • The present disclosure relates generally to wireless detection systems. In one illustrative embodiment, a wireless detection system includes a plurality of surface acoustic wave (SAW) sensors, and an electronic reader for interrogating the plurality of SAW sensors. In some instances, each of the surface acoustic wave based sensors includes an integrated sensor coil. The electronic reader may include a plurality of reader coils and a controller. The controller may be configured to interrogate the plurality of surface acoustic wave based sensors using a time division interrogation. In some cases, each of the plurality of reader coils is inductively coupled to only one of the integrated coils of the SAW sensors at any given time.
    • 本公开一般涉及无线检测系统。 在一个说明性实施例中,无线检测系统包括多个表面声波(SAW)传感器和用于询问多个SAW传感器的电子阅读器。 在一些情况下,每个基于表面声波的传感器包括集成传感器线圈。 电子阅读器可以包括多个读取器线圈和控制器。 控制器可以被配置为使用时分询问来询问多个基于声表面波的传感器。 在某些情况下,在任何给定的时间,多个读取器线圈中的每一个在SAW传感器中只感应耦合到集成线圈中的一个。
