摘要0968736江智阿克伦大学该项目旨在开发一种小型化微流体传感器，通过检测机械生命血液（润滑油）中的金属磨损碎片，对旋转和往复机械进行实时状态监测。拟议的传感器将包括一个基于表面声驻波的创新碎片分离器，可按尺寸对碎片颗粒进行分类，并将它们传送到适当尺寸的探测器，以及一个平行阵列的感应式库尔特计数探测器，可快速分析大量润滑剂。这项工作预计将产生一种具有高吞吐量、高灵敏度、高动态范围和低成本的先进传感器。它将有助于更好地安排包括轴承、变速箱和涡轮机械在内的各种机械的维护计划，从而显着降低机器运行成本。此外，该项目还旨在开发和部署MEMS和传感技术相关的教育材料，并有助于激励K-12学生和来自弱势群体的学生追求STEM职业。将招募本科生（重点是代表性不足的少数族裔和女性）来进行该项目的研究。 通过在现有夏季研讨会上增加的实践活动，中学生和高中生及其老师将接触到尖端的 MEMS 和先进的传感器技术。

Abstract0968736Jiang ZhiUniversity of AkronThis project is to develop a miniaturized microfluidic sensor for real-time condition monitoring of rotating and reciprocating machinery via detecting metal wear debris in the machinery?s life blood, its lubrication oil. The proposed sensor will consist of an innovative debris separator based on surface acoustic standing waves that sorts debris particles by size and delivers them to appropriately-sized detectors, and a parallel array of inductive Coulter counting detectors that enables rapid analysis of a large volume of lubricants. This work is expected to lead to an advanced sensor that has high throughput, high sensitivity, high dynamic range and low cost. It will facilitate better maintenance scheduling for a variety of machinery including bearings, gearboxes, and turbomachinery, thereby significantly reducing the cost of machine operation. In addition, this project also aims to develop and deploy MEMS and sensing technology-related educational materials and contribute to motivating K-12 students and students from underrepresented groups to pursue STEM careers. Undergraduate students will be recruited, with an emphasis on underrepresented minorities and women, to conduct research in this project. Through hands-on activities added to existing summer workshops, middle school and high school students and their teachers will be exposed to cutting-edge MEMS and advanced sensor technologies.
