In previous articles, we introduced the principles and structures of gas sensors. This time, we will discuss the development history of electrochemical gas sensors. The development of electrochemical gas sensors is a history that transitions from theory to practice, from the laboratory to industrial and civilian use, and from single oxygen monitoring to precise detection … Read more
Nitrogen dioxide (NO2) in the air not only causes severe environmental pollution but also poses a significant threat to human health, making it an “invisible killer” that endangers both human health and the environment. Currently, there are many challenges in NO2 sensor technology that severely limit its application: difficulties in operating at room temperature, high … Read more
Fire Hazard Pre-Detection: Detection of Odorous Gases Emitted from Circuit Boards In recent years, the proliferation of IoT has led to the high performance and miniaturization of electrical products, resulting in circuit boards developing towards higher density. This high-density circuit board is at risk of quality degradation due to long-term use and thermal accumulation, which … Read more
Do you remember how dogs smell things? They approach objects, their nostrils constantly flaring, taking short, quick breaths – that’s not just inhaling, they are “sniffing”. Humans also need to detect gases, such as detecting TNT explosives. Can we learn from dogs’ way of smelling to enhance the “sensitivity” of detectors? The sensitivity of a … Read more
