　　报告摘要：Sensor technologies are the foundation of all “smart” technologies,e.g. mobile health, robotics, smart grid, environmental monitoring, structuralhealth monitoring, etc. A major challenge for sensor research is to achievedensely distributed, wireless, low power consumption sensor networks. This talkpresents the study of microwave patch antenna sensors to address thischallenge. We discovered that a microstrip patch antenna can be designed tosense various physical parameters, including strain, pressure, shear, and cracketc. Since the patch antenna also serves as a data transmission device,battery-less wireless interrogation of the antenna sensors can beachieved. In addition, frequency-divisionmultiplexing can be exploited to simultaneously interrogate multi-element sensorarrays. These unique characteristics make the microwave antenna sensor anattractive candidate for densely distributed wireless sensor networks. Theoperating principles of the antenna sensors will be explained first, followedby the discussions of two wireless interrogation schemes. The applications ofthe wireless sensors for strain and crack monitoring will be presented
