Abstract

Abstract Simple and reliable methods for displacement measurements are needed in the areas of sensing, monitoring and actuation. The common methods to measure displacements suffer from issues such as high cost, need for installation space, precise alignment and disturbances in continuous measurements. This paper presents a simple method utilizing a smartphone camera as the primary video capturing device with Matlab to track and measure the deflection of an actuator. The method is validated with known measurements using a microscope micrometer. Further, this paper demonstrates usage of the developed method for measuring the deflection of an actuator based on poly (3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT: PSS) with a least count of 29 microns.

基于智能手机摄像头的微尺度位移测量:在软执行器中的开发与应用

在传感、监测和驱动领域，需要简单可靠的位移测量方法。测量位移的常用方法存在成本高、需要安装空间、精确对准和连续测量中的干扰等问题。本文提出了一种简单的方法，利用智能手机摄像头作为主要的视频捕捉设备，利用Matlab来跟踪和测量致动器的偏转。该方法通过使用显微镜测微计的已知测量进行了验证。此外，本文证明了所开发的方法用于测量基于聚（3，4-亚乙基二氧噻吩）聚苯乙烯磺酸盐（PEDOT:PSS）的致动器的偏转，该致动器的最小计数为29微米。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
