Triboelectric-induced ion mobility for artificial intelligence-enhanced mid-infrared gas spectroscopy

Abstract

Isopropyl alcohol molecules, as a biomarker for anti-virus diagnosis, play a significant role in the area of environmental safety and healthcare relating volatile organic compounds. However, conventional gas molecule detection exhibits dramatic drawbacks, like the strict working conditions of ion mobility methodology and weak light-matter interaction of mid-infrared spectroscopy, yielding limited response of targeted molecules. We propose a synergistic methodology of artificial intelligence-enhanced ion mobility and mid-infrared spectroscopy, leveraging the complementary features from the sensing signal in different dimensions to reach superior accuracy for isopropyl alcohol identification. We pull in “cold” plasma discharge from triboelectric generator which improves the mid-infrared spectroscopic response of isopropyl alcohol with good regression prediction. Moreover, this synergistic methodology achieves ~99.08% accuracy for a precise gas concentration prediction, even with interferences of different carbon-based gases. The synergistic methodology of artificial intelligence-enhanced system creates mechanism of accurate gas sensing for mixture and regression prediction in healthcare.

Roadmap to Human–Machine Interaction through Triboelectric Nanogenerator and Machine Learning Convergence

“…This integration enables real-time monitoring of environmental conditions, facilitating the early detection of pollution, natural disasters, or other environmental risks. By leveraging AI, the TENG system can provide advanced warning systems, helping authorities and communities take proactive measures to mitigate the impact of potential threats. − Specifically, the AI-integrated TENG helps in avoiding risks such as delayed response to pollution incidents, as it can quickly identify unusual patterns in the data indicative of pollution sources. It also aids in the early prediction of natural disasters, allowing for a timely evacuation and resource allocation.…”
