Information technology consists of collection, transmission, and processing, namely sensor, communication, and computer technology. With the integration of technologies such as big data, high computing power, and large models, as well as the arrival of artificial intelligence, the importance of sensors has become more prominent. How to build a complete industrial chain based on semiconductor MEMS process technology and sensitive mechanisms, and form a "dual ecological" industrial synergy system integrating government, industry, academia, research, application, and service, is the urgent task for the development of sensor industrialization.

As the source of information acquisition, sensors are the bridge connecting the physical world and the digital world, and have become an indispensable cornerstone of the information society. It converts various physical quantities, chemical quantities, or biological characteristics into detectable and digitized electrical signals, and is our primary tool for perceiving the world. Sensors play a crucial role in fields such as scientific research, industrial production, national defense and security, and medical health.

In recent years, with the rapid development of flexible electronic technology, flexible wearable sensor devices for monitoring human motion have attracted widespread attention from both academia and industry. Among them, flexible pressure sensors play an important role in monitoring physiological health signals such as pulse, blood pressure, respiration, etc. Fabric based pressure sensors have become an ideal choice for the development of smart wearable electronic products due to their excellent flexibility and breathability. However, currently most fabric based pressure sensors are difficult to accurately monitor pressure signals in the presence of strain interference, which limits their further applications.

Among the numerous innovative achievements of modern technology, infrared pulse sensors are like shining stars, playing an important role in the field of health monitoring. The following will delve into the relevant content of infrared pulse sensors.  

The stability and accuracy of temperature sensors, as key components in modern electronic measurement and control systems, are crucial for the operation of the entire system. And resistance measurement, as an important means of evaluating the performance of temperature sensors, cannot be ignored. This article will delve into the resistance measurement methods and related principles of temperature sensors.

In this article, researchers such as Wang Xiaoyi from Beijing Institute of Technology and Gao Feng from Zhejiang University published a paper titled "A High Performance Surface Acoustic Wave Humidity Sensor with Uniform Multilayer Graphene Oxide Film" in the ACS Sens journal. They studied the use of uniform wrinkled graphene oxide (GO) thin films obtained by vacuum filtration and liquid-phase transfer methods as sensing materials, and proposed a surface acoustic wave (SAW) humidity sensor with comprehensive performance.
