Design and Evaluation of Auxetic Structures as Displacement Sensor

Abstract

In the field of engineering measurement, the displacement sensor is a widely used tool. In this study, a novel method has been developed for measuring displacement. The newly introduced approach aims to address the demand for improved sensitivity, accuracy, and efficiency in displacement measurements, thereby contributing to advancements in various engineering applications and providing valuable insights for future sensor development. The proposed method involves the conversion of stress deformation-induced position changes in auxetic structures into output current changes, providing acceptable measurement accuracy and reliable means of measuring displacement. To evaluate the efficacy of proposed method, three different structures are utilized for analysis and experimental testing in this study, and their performance is comparatively evaluated. The discoveries in this study will present fresh possibilities for employing auxetic materials in the domain of measurement. 3D printing technology is employed for the fabrication of the auxetic structures, rather than conventional subtractive manufacturing methods. 3D printing technology has completely revolutionized various industries, and in the field of measurement, its potential remains largely untapped. By exploring innovative applications, we can expand its utility, simplify the complexity associated with sensor manufacturing, and achieve significant cost reductions. This article delves into the exciting possibilities that 3D printing brings to measurement and sensor production, paving the way for groundbreaking advancements.
