U.S.-France-Sweden Cooperative Research: Ultrasonic Sensors Design, Fabrication and Testing

9912549这个为期两年的奖项支持美国-法国-瑞典在超声显微镜透镜传感器和嵌入传感器的智能材料的设计、制造和测试方面的合作研究。主要研究人员是亚利桑那大学的Tribikram Kundu、法国卡尚高等师范学院的Dominique Placko、S.P.Faure和瑞典乌普萨拉大学的K.Hjort。除了三个主要合作伙伴外，法国ONERA和丹麦奥胡斯大学的研究人员将为合作研究做出贡献。主要目标是利用兰姆波开发新的声学传感器。声学显微镜透镜传感器用于检测微电子设备和飞机结构部件中多层材料的内部缺陷。显微镜兰姆波传感器有可能扫描样品的全部深度，并检测多层固体中不同层的损伤。第二个目标是开展智能结构传感器的研究。这位美国研究人员将基于超声波建模的传感器基本机械设计方面的专业知识带到了这次合作中。此外，乌普萨拉大学的微机械加工专业技术，以及ENS Cachan独特的透镜和智能结构测试和制造设施，都起到了补充作用。该项目将促进对用于声学显微镜的兰姆波透镜设计的理解，并可能生产一种新的超声波传感器。

9912549KunduThis two-year award supports U.S.-France-Sweden cooperative research on the design, fabrication and testing of ultrasonic microscope lens sensors and smart materials embedded with sensors. The principal investigators are Tribikram Kundu of the University of Arizona, Dominique Placko, S.P. Faure of the Ecole Normal Superieure de Cachan, France, and K. Hjort of Uppsala University in Sweden. In addition to the three major partners, researchers at ONERA, France and the University of Aarhus, Denmark will contribute towards the collaborative research. The principal objective is to develop new acoustic sensors using Lamb waves. Acoustic microscope lens sensors are used to detect internal defects in multilayered materials in microelectronic devices and in airplane structural components. Microscope lamb wave sensors have potential to scan the full depth of a specimen and detect damages in different layers in a multilayered solid. A second objective is to conduct research on sensors for smart structures. The U.S. investigator brings to this collaboration expertise on the basic mechanical design of sensors based on ultrasonic modeling. This is complemented by the micro-machining expertise at Uppsala University, access to unique facilities for testing and fabricating lenses and smart structures at ENS Cachan. The project will advance understanding of Lamb wave lens design for acoustic microscopy and could produce a new ultrasonic sensor.
