这项工作的主要目标是开发低成本、无线、无电源、谐振的传感器网络，可用于监测民用基础设施系统中的大片区域。一个关键的新研究领域涉及将单个传感器耦合到一个网络中，以产生集体的、水晶般的行为，从而允许大面积覆盖并对损害高度敏感。我们正在研究被动谐振传感器阵列中的这种集体现象。其目标是提供有关传感器阵列内任何位置的腐蚀(或其他一些目标)的信息。电子结构监视(ESS)网络是由一组电感耦合的谐振传感器组成的，例如我们以前工作中开发的那些传感器。在这里，我们提出的结果显示了这样一个系统的集体行为，它应该导致更大的面积覆盖和更灵敏的小缺陷检测。
The primary objective of this work is the development of low-cost, wireless, unpowered, resonant sensor nets that can be used to monitor large areas in civil infrastructure systems. A critical new area of research relates to the coupling of individual sensors into a net to produce collective, crystal-like behavior, allowing large area coverage with high sensitivity to damage. We are investigating such collective phenomena in arrays of passive resonant sensors. The goal is to provide information about corrosion (or some other ldquotargetrdquo) anywhere within the sensor array. An electronic structural surveillance (ESS) net is formed from an array of inductively coupled, resonant sensors, such as those developed in our previous work. Here we present results showing the collective behavior of such a system that should lead to both larger areal coverage and more sensitive detection of small defects.
