SEMINAR: Distributed Sensing for Mechanical and Biomedical Systems

November 1, 2019 @ 10:00 am - 11:30 am

Event Navigation


Sensor technologies are the foundation of all “smart” technologies, e.g. mobile health, robotics, smart grid, environmental monitoring, structural health monitoring, etc. A major challenge for sensor research is to achieve densely distributed, wireless, low power consumption sensor networks. This talk presents the study of microwave patch antenna sensors to address this challenge. We discovered that a microstrip patch antenna can be designed to sense various physical parameters, including strain, pressure, shear, and crack etc. Since the patch antenna also serves as a data transmission device, battery-less wireless interrogation of the antenna sensors can be achieved.  In addition, frequency-division multiplexing can be exploited to simultaneously interrogate multi-element sensor arrays. These unique characteristics make the microwave antenna sensor an attractive candidate for densely distributed wireless sensor networks. The operating principles of the antenna sensors will be explained first, followed by the discussions of two wireless interrogation schemes. Recent progresses on studying the wireless sensors for condition monitoring in harsh environment will be presented.
