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.

摘要0968736江志阿克伦大学本项目旨在开发一种微型微流控传感器，通过检测机械中的金属磨损碎屑，对旋转和往复运动机械进行实时状态监测。它的生命之血，它的润滑油。拟议的传感器将包括一个基于表面声波驻波的创新碎片分离器，该分离器按大小对碎片颗粒进行分类，并将其传送到适当大小的探测器，以及一个平行的感应库尔特计数探测器阵列，该探测器能够快速分析大量润滑剂。这项工作有望导致一个先进的传感器，具有高通量，高灵敏度，高动态范围和低成本。它将有助于更好地为各种机器（包括轴承、齿轮箱和减速器）制定维护计划，从而显著降低机器运营成本。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学生和来自代表性不足群体的学生追求STEM职业。将招募本科生，重点是代表性不足的少数民族和妇女，在这个项目中进行研究。 通过在现有的暑期工作坊中增加实践活动，初中和高中学生及其教师将接触到尖端的MEMS和先进的传感器技术。
