Design and Fabrication of Polymer Rubber-CNTs-Based Displacement Sensors Using Vibration Technique
摘要
In this paper we described the fabrication of polymer rubber – carbon nanotubes (CNTs) – based displacement sensors using vibration deposition technique. The CNT films deposited by this technique were mechanically strong. It was found that under the effect of displacement up to 0.15 mm the resistance and the impedance of the sensors decreased by 4.3 times and 3.2 times, respectively. While under the same displacement the capacitance increased up to 3.08 times at 100 kHz and 1.85 times at 200 kHz. The fabricated sensors were shockproof. The introduced fabrication technology was simple for control and easy for realization. Similarly, the used materials were cost-effective and ecologically friendly. The fabricated devices are related to the “elastic electronics”. The vibration technology introduced in this work may be used for the fabrication of electronic devices at lab (research and teaching purposes) and commercial scales as well.
