Summary: This paper presents a suite of wireless sensing solutions for continuous monitoring of transportation infrastructure, including both traditional and emerging sensor technologies. Various pavement sensing technologies are discussed, and a suitability assessment survey is conducted to select appropriate inter-sensor and gateway-to-cloud communication technologies. Recommendations are made based on a multi-disciplinary analysis considering strengths, weaknesses, opportunities, and threats (SWOT) of different communication technologies and proposed wireless architectures for smart mobility sensing infrastructure (SISM). Additionally, recommendations are provided for implementing the proposed wireless architectures for wireless and continuous monitoring of transportation infrastructure at the proposed Illinois Autonomous and Connected Track (I-ACT) at the University of Illinois Urbana-Champaign.

Summary: Hydrolysis-resistant CsPbBr3/reduced graphene oxide nanoscrolls (CsPbBr3/rGO NSs) with excellent optical properties and stability were obtained through a solvent-assisted self-rolling process. The CsPbBr3 QDs embedded in rGO nanosheets prevent water infiltration and maintain superb optical properties. The CsPbBr3/rGO NSs exhibit enhanced anode photocurrent response and demonstrate high sensitivity and anti-interference ability in molecular imprinted PEC sensors for mycotoxin detection.

Summary: Conductive gels have great potential in wearable sensing due to their conductivity, softness, stretchability, and biocompatibility. However, traditional conductive gels face challenges in underwater sensing due to swelling and loss of conductivity in aqueous environments. Advances in improving water resistance and application of conductive gels in underwater sensing have been made, but a comprehensive review is lacking. This review provides an overview of design strategies for developing water-resistant conductive gels and their applications in underwater sensing as wearable sensors, as well as discusses ongoing challenges and future recommendations.
