MRI: Development of a Novel Wireless Sensor System Test-Bed for Infrastructure Monitoring and Biomedical Applications

一种新型的无线传感器系统测试平台的发展基础设施健康监测和生物医学应用近年来已经看到了巨大的兴趣，在无线传感器的应用范围从包裹跟踪到基础设施健康监测和远程医疗植入疾病诊断。目前，由于缺乏对传感器系统级性能指标的了解，有效传感器的开发受到抑制。该项目的目标是开发一种新型的无线传感器系统测试平台，在该平台内，传感器将被设计和测试用于基础设施健康监测和生物医学应用。智力优势：该项目中提出的独特的无线传感器测试平台目前还不存在。大多数远场室的局限性在于其巨大的成本和复杂性，因为它们被设计为测量天线和收发器特性的各种阵列。这项工作将开发一个小型，低成本，便携式无线传感器测试平台，这将被用来测量的范围和数据链路裕度的无线传感器作为功能的阅读器输出功率，天线类型和嵌入介质。 该项目包括开发一个非辐射和辐射特性测试平台。第一个组件将包括简单的制造、集成和测试设施，以评估非辐射性能，而第二个组件将包括进行辐射测试的仪器，以测量功率和数据链路裕度。 更广泛的影响：新型无线传感器系统测试平台将有助于创建具有高效率和数据吞吐量的微型无线传感器。开发的技术将提供给学术机构和商业公司使用。本项目开发的仪器基础设施将成为促进南卡罗来纳州经济增长的资产。该项目将培训研究生和本科生，并将吸收代表性不足的群体和少数民族的学生参加。

Development of a Novel Wireless Sensor System Test-Bed for Infrastructure Health Monitoring and Biomedical Applications Recent years have seen tremendous interest in wireless sensors for applications ranging from package tracking to infrastructure health monitoring and telemedicine to implanted disease diagnosis. The development of efficient sensors is currently inhibited due to a lack of knowledge on their system level performance metrics. The goal of this project is to develop a novel wireless sensor system testbed within which sensors will be designed and tested for infrastructure health monitoring and biomedical applications. Intellectual Merit:The unique wireless sensor test-bed proposed in this project does not currently exist. The limitation of most far-field chambers lies in their enormous cost and complexity since they are designed to measure a diverse array of antenna and transceiver characteristics. This work will develop a small, low cost, portable wireless sensor testbed, which will be used to measure the range and data link margin of a wireless sensor as function of the reader output power, antenna type and embedding medium. The project consists of developing a non-radiated and a radiated characterization testbeds. The first component will consist of simple fabrication, integration and test facilities to assess the non-radiated performance while the second component will consist of instrumentation to conduct radiated tests to measure power and data link margin. Broader Impact:The novel wireless sensor system testbed will help create miniature wireless sensors with high efficiency and data throughput. The technology developed will be made available for use by academic institutions and commercial companies. The instrumentation infrastructure developed in this project will be an asset to foster economic growth in the state of South Carolina. The project will train graduate and undergraduate students and will involve students from underrepresented groups and minorities.
