Abstract
Sensor technology is the foundation of all “smart” technologies, e.g. structural health monitoring, mobile health, robotics, smart grid, etc. This talk presents three diverse projects related to advanced sensor development for health monitoring of structures, materials and humans. The first project addresses the major challenge of achieving densely distributed and low power wireless sensor networks. We discovered that microstrip patch antennas can be designed to sense various physical parameters, including strain, temperature, pressure, shear, crack, etc. Serving the dual function of sensing and data transmission, the patch antenna can be wirelessly interrogated without an on-board battery. In addition, multiple wireless antenna sensors can be interrogated simultaneously through frequency division multiplexing. The studies of the microwave antenna sensors for prosthetic socket monitoring and high temperature applications will also be presented. The second project investigates the realization of a wireless ultrasound inspection system as well as the study of the transducer adhesive layer for optimized ultrasound generation. The 3rd project focuses on identifying a quantifiable physical parameter that can represent early fatigue damage in metallic materials, which establishes the theoretical foundation for future sensor development.
