Abstract:

During Year 5 of SAFETEA-LU, ITI researcher Professor Yonggang Huang, an expert in the science of stretchable and flexible electronics, collaborated with researchers at University of Illinois to engineer stretchable and flexible piezoresistive strain sensors and multiplexed arrays for advanced structure health monitoring of transportation infrastructures. The piezoresistive strain sensors and multiplexed arrays cover a finite area of the surface of transportation infrastructures, and provide the spatial distribution of strain. These sensors and multiplexed arrays are particularly suitable for curvilinear surfaces with sharp corners, which usually have stress or strain concentrations and require accurate sensing. In addition, the gauge factor of piezoresistive strain sensors is more than two orders of magnitude higher than conventional strain sensors. They can measure much more accurately the maximum strain in the critical components (e.g., sharp corners, complex shapes) of the transportation infrastructure experiences.
