Abstract

A modified Interdigitated Planar Electrode (IDE) design is presented and used in the development of flex-sensor for Structural Health Monitoring (SHM). The design of IDE consists of a U-shaped electrode with integrated interdigitated electrodes. The overall size of the unit-cell structure is 25 × 25 mm2. Different civil engineering blocks were tested using the proposed sensor and a comprehensive crack analysis is presented based on the crack parameters. The sensor offers a lowest average sensitivity of 0.863157 pF/mm. The proposed flex-sensor can also be potentially used for the detection and monitoring of other structural parameters like corrosion, moisture content etc.

用于土木工程结构损伤检测的交叉数字化平面电容式挠性传感器阵列的研制

提出了一种改进的交叉指状平面电极(IDE)设计，并将其用于结构健康监测(SHM)柔性传感器的研制。IDE的设计由一个u形电极和集成的交叉电极组成。单胞结构的总体尺寸为25 × 25 mm2。利用该传感器对不同的土木工程砌块进行了测试，并基于裂缝参数进行了全面的裂缝分析。该传感器的最低平均灵敏度为0.863157 pF/mm。所提出的柔性传感器也可以潜在地用于检测和监测其他结构参数，如腐蚀，水分含量等。
