Recent Progress on Sensors of Conductive Aerogels

ABSTRACT Conductive aerogels, characterized by their panoscopic 3D interconnected porosity and exceptional signal transduction capabilities, are revolutionizing the landscape of next‐generation sensing platforms. Despite rapid breakthroughs in material synthesis, a critical challenge remains in establishing a systematic structure‐performance roadmap that correlates hierarchical nano‐architectures with the reliability and environmental sustainability required for practical sensing ecosystems. This review provides a timely and comprehensive synthesis of the recent evolution in conductive aerogel sensors, bridging the gap between fundamental building‐block design and multi‐modal application integration. We critically evaluate the state‐of‐the‐art across carbon‐based, metal, MXene, and conductive polymer aerogels, highlighting how precise control over interfacial engineering and pore‐network topology modulates sensitivity, linearity, and detection ranges. Crucially, special emphasis is placed on green manufacturing strategies and the transition toward autonomous, self‐powered sensing systems, aligning with the core tenets of the circular economy and sustainable development. By identifying current technical bottlenecks—such as the trade‐off between mechanical robustness and signal stability—this work offers a forward‐looking perspective for the rational design of eco‐friendly, intelligent aerogel sensors in wearable healthcare and environmental monitoring.
