Detection of fatigue crack propagation through damage characteristic FWHM using FBG sensors

Meng Zhang, Weifang Zhang, Xiaobei Liang, Yan Zhao, Wei Dai

Crack damage detection for aluminum alloy materials using fiber Bragg Grating (FBG) sensor is a kind of structure health monitoring. In this paper, the damage index of full width…

Role of defects in electron band structure and gas sensor response of La2CuO4

Chinmay Roy, Aparna Ghosh, Suman Chatterjee

This paper aims to estimate the relationship between defect structure with gas concentration for use as a gas sensor. The change in defect concentration caused a shift in the…

Assistive cane for visually impaired persons for uneven surface detection with orientation restraint sensing

Bhupendra Singh, Monit Kapoor

The reduced ability of eyes to see clearly even with the use of glasses is known as the state of visual impairment. Among the many challenges faced, outdoor travel is one of them…

High-precision width measurement method of laser profile sensor

Yu Feng, Wei Tao, Yiyang Feng, Xiaoqia Yin, Na Lv, Hui Zhao

Although a laser profile sensor (LPS) can be used to measure dimensions, the “shadow region” generally degrades the accuracy and precision of width measurements. The accuracy and…
