Abstract

Angular motion measurement using commercial sensing technologies can be challenging due to the nonlinearity of the motion and the combination of translational, oscillatory, and rotational behaviors. Recent advances in hyperelastic and self-sensing materials have facilitated the development of flexible electronics, enabling robust and cost-effective angular motion sensing systems. The authors have recently proposed a flexible strain sensor termed corrugated soft elastomeric capacitor (cSEC). The cSEC is a thin-film, ultra-compliant, and scalable sensor that transduces geometric variations into a measurable change in capacitance. It is constituted by layering two conductive plates sandwiching a dielectric that is surfacecorrugated. In this paper, we study the use of the cSEC for angular motion sensing of a free rotational hinge, in which the cSEC was adhered onto the rotating area of the hinge subjected to an axial displacement generating clockwise and counterclockwise angular rotations.

大角运动监测用软弹性电容器的研究

由于运动的非线性以及平移、振荡和旋转行为的组合，使用商业传感技术进行角运动测量可能具有挑战性。超弹性和自传感材料的最新进展促进了柔性电子的发展，使鲁棒和经济高效的角运动传感系统成为可能。作者最近提出了一种柔性应变传感器，称为波纹软弹性电容器(cSEC)。cSEC是一种薄膜、超兼容、可扩展的传感器，可将几何变化转换为可测量的电容变化。它是由分层的两个导电板夹在表面波纹的电介质上构成的。在本文中，我们研究了将cSEC用于自由旋转铰链的角运动传感，其中cSEC粘附在铰链的旋转区域上，受到轴向位移产生顺时针和逆时针的角旋转。
