A proton polymer electrolyte based on polybenzimidazole has been proposed for hydrogen sensors operating at room temperature in air. The potential response in inert gas containing hydrogen conforms to the Nernst equation. In air, the electromotive force is a mixed potential resulting from the combined effects of hydrogen oxidation and oxygen reduction. Regardless of the … Read more
Electrochemical gas detection elements require a constant bias to operate accurately, which can consume a significant amount of power. When the device is in idle or sleep mode, normal power management systems often attempt to keep these devices turned off. However, electrochemical sensors may take tens of minutes or even hours to stabilize. Therefore, the … Read more

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
Accurate diagnosis and staging of breast cancer are crucial for guiding clinical treatment strategies and predicting patient survival outcomes. Current clinical methods face limitations in detecting small tumors and micrometastases, such as imaging techniques; although biopsy remains the gold standard, its invasiveness makes it unsuitable for repeated use. Liquid biopsy is a promising solution that … Read more
Real-time biochemical monitoring is crucial in personalized medicine and disease diagnosis. Fiber electrochemical sensors have become ideal carriers for wearable devices due to their miniaturization and biocompatibility advantages. However, traditional surface functionalization preparation strategies lead to two major bottlenecks: first, the active materials are prone to delamination from the high-curvature fiber surface, resulting in mechanical … Read more
