All carbon-based sensors play a critical role in ensuring the sustainability of smart packaging while enabling real-time monitoring parameters such as humidity, temperature, pressure, and strain during transit. This systematic review covers literature between 2013 16 November 2024 Scopus, Web Science, IEEE Xplore, Wiley databases, focusing on sensor materials, structural design, fabrication technologies that contribute to maximizing performance scalability with particular emphasis food pharmaceutical product applications. After being subjected inclusion exclusion criteria, 164 studies were included this review. The results show most humidity are made using graphene oxide (GO), though there is some progress toward cellulose cellulose-based materials. Graphene carbon nanotubes (CNTs) predominant temperature mechanical sensors. application composites design (e.g., porous 3D structures) significantly improves sensitivity, long-term stability, multifunctionality, whereas manufacturing methods spray coating printing further drive production scalability. transition from metal electrodes could also reduce cost. However, scalability, real-world validation remain challenges be addressed. Future research should enhance through low-energy techniques development sustainable advanced materials provide solutions for practical applications dynamic transportation environments.

Graphene is considered an excellent material for biomedical applications because of its outstanding antimicrobial performance. However, the high synthesis cost and complexity make it difficult to apply this in numerous fields. This research focuses on synthesizing graphene nanoparticles (NPs) cost-effectively simply. Cost-effective chemicals were used here NPs. A simple easy technique has been followed throughout process. The synthesized NPs characterized by ultraviolet–visible (UV) spectroscopy, scanning electron microscopy (SEM), transmission (TEM), energy-dispersive X-ray (EDX) analyses. TEM analysis revealed size structure nanosized Excellent properties 99.99% bacterial inhibition against gram-negative bacterium E. coli have obtained. findings indicate potential different sectors their improved properties.

Abstract We propose a strain application process and structure for chemisorption-based resonant mass sensor using graphene, aiming to develop novel sensing platform with high sensitivity selectivity. The results demonstrate the successful of 0.26%–0.30% suspended graphene through thermal shrinkage SU-8, resulting in 25% improvement resonance characteristics. Furthermore, we demonstrated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spikes chemisorbed on strain-applied sensor, achieving 149,000 times higher than that silicon-based chemisorption sensors.
