A laser-reduced graphene oxide (LrGO) sensor offers a low-cost, scalable, and additive-free solution for real-time detection of ammonia and ethanol gases. Fabricated directly on PET films via laser reduction, the sensor achieves sensitivities of 0.0402 %/ppm for ammonia and 0.0140 %/ppm for ethanol at room temperature. With simple fabrication, stable performance, and strong linear response, LrGO enables sustainable, eco-friendly gas sensing for environmental and workplace safety monitoring.
Mercury (Hg²⁺) contamination poses severe health risks, yet current detection is slow and costly. This study introduces a breakthrough MoS2-functionalized MgZnO/CdZnO high-electron-mobility transistor (HEMT) sensor for ultrasensitive detection of Hg²⁺ ions. Using chemical vapor–deposited grown MoS2, the device could detect mercury ions at an ultralow concentration (as low as 6.5 ppt) within 4 seconds. This highly selective, portable solution provides reliable, real-time monitoring for water quality and environmental surveillance.

Thermal fault detection is crucial for maintaining industrial blowers, as high-speed rotation can lead to overheating and performance loss. The proposed system combines thermal infrared and visible images using an Improved Diffusion-Based Fusion (IDF) model. A lightweight Convolutional Cross-Attention Encoder Network (CCAE-Net) analyzes these images, segmenting components and identifying abnormal temperature zones. This method enables accurate, real-time monitoring, enhancing the reliability, efficiency, and safety of high-speed direct-driven blowers.

RFID-a radio-frequency identification technology, is gaining popularity as a wireless sensor for track and trace applications. The high cost of chipped-RFID tags makes them unsuitable for mass production. The Chipless-RFID tag is lightweight, durable, reliable, and energy-sufficient and can be mass-produced using inexpensive conductive inks or yarns. Improving range and data capacity in chipless-RFID tags could make them indispensable as wearables.
