Light-activated chemiresistors offer a powerful approach to achieving lower-temperature gas sensing with unprecedented sensitivities. However, an incomplete understanding of how photoexcited charge carriers enhance sensitivity obstructs the rational design high-performance sensors, impeding practical utilization under commonly accessible light sources instead ultraviolet or higher-energy sources. Here, is presented modulate electronic properties parent metal oxide phase, exemplified by this model system Bi-doped In

Abstract Vibration sensors for continuous and reliable condition monitoring of mechanical equipment, especially detection points curved surfaces, remain a great challenge are highly desired. Herein, flexible adaptive triboelectric vibration sensor high‐fidelity conditions is proposed. The entirely composed materials. It consists conductive sponge‐silicone layer fluorinated ethylene propylene film. can detect acceleration 5 to 50 m s −2 frequency 10 100 Hz. has strong robustness stability, the output performance barely changes after durability test 168 000 working cycles. Additionally, work even when point equipment curved, linear fit voltage very close that flat. Finally, it be applied blower vehicle engine, transmit signal mobile phone application through Wi‐Fi module real‐time monitoring. expected provide practical paradigm smart, green, sustainable wireless system in era Internet Things.

Nutritional status monitoring plays an important role in the maintenance of human health and disease prevention. Monitoring intake vitamins can support improvement diet behavior. In this work, a polyaniline (PANI) film-based nonenzymatic electrochemical sensor was prepared to track vitamin C level sweat. The PANI film modified with organic acids (ethylformic acid, malic tartaric phytic acid). acid-modified based on has wide detection range (0.5-500 μmol·L-1), high sensitivity (665.5 326.2 μA·(mmol·L-1)-1·cm-2), low limit (0.17 μmol·L-1) toward phytate enhances band transport between chains, which increases electrical conductivity improve properties sensor. addition, we monitored changes levels body after taking pills by detecting sweat or saliva. ability pharmacological profile demonstrates potential sensors for applications personalized nutritional tracking. And simple portable system developed practicability This work provides idea application wearable sensing devices nutrition guidance.

Gas sensors have played a critical role in healthcare, atmospheric environmental monitoring, military applications and so on. In particular, flexible sensing devices are of great interest, benefitting from flexibility wearability. However, developing gas with high sensitivity, stability workability is still challenging. this work, multi-walled carbon nanotubes (MWCNTs) were grown on polydimethylsiloxane (PDMS) films, which further modified polyaniline (PANI) using simple chemical oxidation synthesis. The superior the PANI-MWCNTs/PDMS film enabled stable initial resistance value, even under bending conditions. sensor showed excellent NH3 performances, including response (11.8 ± 0.2 for 40 ppm NH3) low limit detection (10 ppb) at room temperature. Moreover, effect humid environment performances was investigated. results show that enhanced humidity conditions because water molecules can promote adsorption films. addition, had abilities detecting simulated breath patients kidney disease freshness shrimp. These above reveal potential application monitoring human food.
