Article Abstract
Accurately assessing potential side effects following botulinum neurotoxin (BoNT) injection remains a formidable challenge. To address this issue, an innovative approach is developed that combines a wearable temperature sensor with a sophisticated volatilomics technique, aimed at facilitating the rapid and convenient prediction of potential physical discomfort related to latrogenic botulism. The investigation identifies five volatile organic compounds (VOCs)-acetone, styrene, ethanol, 2-pentanone, and n-butano-as promising markers indicative of BoNT poisoning. Specifically, a handheld breath analyzer, featuring a yttrium stabilized zirconia (YSZ)-based gas sensor array, alongside a wearable temperature sensor integrated with a bio-compatible methacrylated gelatin (GelMA) sensing film, are developed to simultaneously monitor breath signal variations and body temperature fluctuations. Preliminary animal testing validates the effectiveness of the integrated approach, achieving an accuracy exceeding 91.2% in early detection of physical discomfort associated with BoNT poisoning. These promising findings represent a significant advancement towards the early identification of BoNT-related issues, enabling timely intervention and improved management strategies.

Ionic conductive hydrogels show promise for flexible sensors in wearables and e-skins, but balancing mechanical strength with high conductivity remains challenging. Herein, a triple-network ionic conductive hydrogel based on poly(acrylic acid) (PAA) was developed, synergistically reinforced by dissolved cellulose (dCel) and aramid nanofibers (ANF), with Al/Zn bimetallic ions serving as the conductive medium. Intriguingly, dCel was in-situ generated using the concentrated Al/Zn bimetallic salt solutions as the cellulose solvent, following the complete dissolution of the pulp fibers driven by the intensive ionic hydration of Al/Zn ions.

The practical implementation of wearable sensing devices for human health monitoring requires significant advancements in lightweight design and multifunctional integration. Fiber-shaped sensors have attracted considerable research attention due to their ability to maintain exceptional sensitivity and measurement accuracy under various mechanical deformations, including bending, stretching, and torsion. Nevertheless, the functional integration remains constrained, particularly as evidenced by sensitivity degradation and device failure under extreme high-temperature conditions, which severely hinders their practical applicability for real-time health monitoring applications in complex environmental scenarios.

Human factors are central to aviation safety, with pilot cognitive states such as workload, stress, and situation awareness playing important roles in flight performance and safety. Although flight simulators are widely used for training and scientific research, they often lack the ecological validity needed to replicate pilot cognitive states from real flights. To address these limitations, a new in-flight data collection methodology for general aviation using a Cessna 172 aircraft, which is one of the most widely used aircraft for pilot training, is presented.
