Battery-Free Antenna Sensors For Strain And Crack Monitoring: Data Report, Yang Wang, Dan Lin

Project SN-2

A total of 15 data sets are submitted along with the final project report. The submission contains a combination of simulated and experimental data sets. The formats include text files (both *.txt and *.tff), MATLAB data *.mat files, and MATLAB plotting code *.m files.

The simulation and experimental procedures generating each data set is elaborated in detail in the final report, and are thus not repeated herein. Upon unzipping the data package, the 15 data sets can be seen organized in 15 subfolders (some in the first level and some in the second level subfolders).

To help a reader relate …

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 …
