Battery-Free Antenna Sensors For Strain And Crack Monitoring -- Technical Report (2017-2020), Yang Wang, Dan Lin Jan 2020

Battery-Free Antenna Sensors For Strain And Crack Monitoring -- Technical Report (2017-2020), Yang Wang, Dan Lin

Project SN-2

This project studies a wireless patch antenna as a novel strain/crack sensing technique for structural health monitoring (SHM). The strain/crack-induced resonance frequency shift of the antenna can be wirelessly detected and utilized to estimate the surface strain and crack propagation. However, temperature fluctuation can generate some unwanted changes in resonance frequency and introduce significant noises in measurement. This project studies a thermally stable patch antenna sensor through both numerical simulations and laboratory experiments. Using a substrate material with a steady dielectric constant, a patch antenna sensor is designed to perform reliably under temperature fluctuations. In addition, a dual-mode patch antenna …
