Biodegradable, Humidity‐Insensitive Mask‐Integrated E‐Nose for Sustainable and Non‐Invasive Continuous Breath Analysis

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 24, 2025

Abstract Breath analysis offers a non‐invasive approach to modern diagnostics by capturing volatile organic compounds (VOCs) in exhaled breath. However, current breath technologies face challenges like humidity sensitivity, high costs, and biodegradable solutions, limiting their scalability environmental sustainability. This study presents paper‐based, biodegradable, humidity‐insensitive electronic nose (e‐nose) sensor array integrated into mask for real‐time analysis. The sensors, coated with hydrophobic polymer coating, ensure robust insensitivity humidity, enabling reliable detection of VOCs even high‐moisture environments. mask‐integrated e‐nose facilitates monitoring applications such as alcohol consumption tracking respiratory health assessment. For the latter, Tuberculosis (TB) is selected representative use case, achieving 89% accuracy disease diagnosis recovery using pre‐trained deep‐learning model. fully‐biodegradable paper‐based naturally degrades soil within months, underscoring its eco‐friendly design suitability disposable monitoring. work introduces sustainable, user‐friendly potential personalized healthcare
