Abstract

─ In this paper, we propose a newly developed impedance method to gauge the variations of multidirectional strain using a near-circular-patch based sensor. A novel three-dimensional (3D) feeding mechanism realized by a 90-deg bended microstrip line is devised for allowing strain detection along any direction in the azimuth plane of a metallic surface. The simulated results, verified by experimental results, demonstrate that there is a linear relationship between normalized impedance and multi-directional strain with high sensitivities of about 100 ppm/με. The relationship between sensitivity and sensor orientation is derived as a cosine function, which is a useful feature for estimating principal strain direction. Index Terms ─ 3D feeding mechanism, multidirectional strain monitoring, near-circular-patch, strain sensor.

用三维微带线馈电近圆贴片天线实现的新型多向应变传感器

在本文中，我们提出了一种新开发的阻抗方法来测量基于近圆贴片的传感器的多向应变变化。设计了一种基于90度弯曲微带线的三维进给机构，用于金属表面方位面任意方向的应变检测。仿真结果与实验结果相吻合，表明归一化阻抗与多向应变呈线性关系，灵敏度约为100 ppm/με。灵敏度与传感器方向之间的关系被导出为余弦函数，这是估计主应变方向的有用特征。关键词:三维送料机构，多向应变监测，近圆贴片，应变传感器。

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
