Abstract Biofilm formation on food packaging surfaces is a major issue in the industry, as it leads to contamination, reduces shelf life, and poses risks human health. To mitigate these effects, developing smart coatings that can actively sense combat microbial growth has become critical research focus. This study motivated by need for intelligent solutions integrate antimicrobial agents sensors real‐time contamination detection. It hypothesized combining conducting polymers (CPs) with nanomaterials enhance efficacy while maintaining mechanical integrity environmental stability required applications. Through application of numerous technologies like surface modification, CP–nanoparticle integration, multilayered coating, performance sensor capabilities materials were analyzed. Case studies showed 90% inhibition bacterial tenfold decrease viable counts AgNPs incorporation, extending strawberries’ life 40% fish freshness an additional 5 days. Moreover, CP complex systems have been shown reduce oxidative spoilage nuts dried fruits up 85%, quality leafy greens 3 weeks under suboptimal conditions. Environmental assessments indicated 30% reduction carbon footprint when combined biodegradable polymers, contributing more transparent reliable supply chain. CP‐based films integrated exhibit high sensitivity, detecting ammonia concentrations below 500 ppb, offer significant selectivity sensing hazardous gases.

Conductive polymer hydrogels (CPHs) are widely employed in emerging flexible electronic devices because they possess both the electrical conductivity of conductors and mechanical properties hydrogels. However, poor compatibility between conductive polymers hydrogel matrix, as well swelling behavior humid environments, greatly compromises CPHs, limiting their applications wearable devices. Herein, a supramolecular strategy to develop strong tough CPH with excellent anti-swelling by incorporating hydrogen, coordination bonds, cation-π interactions rigid conducting soft matrix is reported. Benefiting from effective networks, obtained has homogeneous structural integrity, exhibiting remarkable tensile strength (1.63 MPa), superior elongation at break (453%), toughness (5.5 MJ m-3 ). As strain sensor, possesses high (2.16 S m-1 ), wide linear detection range (0-400%), sensitivity (gauge factor = 4.1), sufficient monitor human activities different windows. Furthermore, this resistance been successfully applied underwater sensors for monitoring frog swimming communication. These results reveal new possibilities amphibious sensors.
