Abstract

The bubbles generated in water of lake or sea have a negative effect on organism, ecosystems and underwater equipment. However, bubbles have the characteristics of random distribution and irregular dynamic changes in flow status, making it difficult to detect them. Hence, intelligent devices are urgent needed to monitor these water environments. Triboelectric nanogenerator (TENG) opens up a possibility to solve these problems. In this study, a bubble detecting triboelectric nanogenerator (BD-TENG) based on polyamide 12 (PA12) was fabricated to qualitatively measure the content of bubbles in tubes. A series of peak open-circuit voltage (Voc) of approximately 26 V were appeared when bubbles are presented in great quantity, while that of a stable value around 9 V at no bubbles state. Additionally, the effect of fluid velocity, bubble volume, generating materials and bubble injection rate was systematically studied. Finally, the performance of CO₂ bubble detection of BD-TENG was examined in a mimic water environment, and the Fast Fourier transform (FFT) method are used to make the measured data much more intuitive. This study may provide an effective approach for detecting bubbles.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
