This paper presents the proposal and characterisation of a flexible, shockproof, vibration-free, longitudinal and transversal compressive displacement sensor based on a composite of CI Disperse Orange 25 and carbon nanotubes created with an energy-free, drop-casting technique. The structural morphology of each layer is studied briefly through X-ray diffraction. Electric investigations of the sensors in the form of impedance were performed as a function of longitudinal and transversal compressive displacement at three different frequencies. The compressive displacements were measured from 0 to 250 µm at three fixed frequencies (ie, 1, 10 and 200 kHz). The impedance has an inverse relationship with longitudinal compressive displacement but a direct relationship with transversal compressive displacement. The frequency to impedance relationship is inverse with the sensitivity of the impedance as a function of longitudinal displacement. Because of their small size, light weight and simple fabrication technique and design, as well as their low cost and maintenance, these types of devices can be utilised across a wide range of medical applications, such as in rehabilitation centres, for machine status assessment during physiotherapy, and in robotic body parts, as well as for educational purposes in universities.

基于 CI Disperse Orange 25 和碳纳米管复合材料的柔性纵向和横向位移传感器

本文介绍了一种基于 CI Disperse Orange 25 和碳纳米管的复合材料的柔性、防震、无振动、纵向和横向压缩位移传感器的建议和表征，该复合材料采用无能量滴铸技术制造。通过 X 射线衍射对各层的结构形态进行了简要研究。阻抗形式的传感器的电气研究是作为三个不同频率下的纵向和横向压缩位移的函数进行的。在三个固定频率（即 1、10 和 200 kHz）下测量 0 到 250 µm 的压缩位移。阻抗与纵向压缩位移成反比关系，但与横向压缩位移有直接关系。频率与阻抗的关系与作为纵向位移函数的阻抗灵敏度成反比。由于它们体积小、重量轻、制造技术和设计简单，以及成本和维护成本低，这些类型的设备可用于广泛的医疗应用，例如在康复中心，用于评估期间的机器状态。物理治疗，机器人身体部位，以及大学的教育目的。
