With the rapid advancement of modern science and technology, sensor technology has emerged as a vital discipline that is closely intertwined with contemporary scientific progress. It has found widespread application in various fields such as industrial automation, aerospace, military engineering, medical diagnostics, and intelligent transportation. Innovations in technologies like MEMS (Micro-Electro-Mechanical Systems), laser technology, and advanced materials have further diversified the development of sensors. Let’s explore this fascinating field together through the lens of network communication.
Sensor technology acts as a crucial bridge for technological development across multiple industries. Recently, thousands of sensors were deployed to monitor the structural health of bridges in Wuhan, Hubei, making it a hot topic in the sensor industry. The first phase of the Wuhan City Bridge Smart Management System was launched, with over 1,000 sensors installed on more than 30 bridges to ensure their safety and stability. These sensors cover key structures like Wujindi Interchange, Parrot Interchange, and others. According to experts from the China Railway Bridge Science Research Institute, the sensors continuously monitor the bridge's structural condition, foundation settlement, and traffic load in real time. All data are stored in cloud computing centers, enabling round-the-clock automatic monitoring of the bridges.
Beyond Wuhan, cities like Hefei in Anhui have also implemented smart bridge monitoring systems. With 387 sensors, they monitor critical structures such as the Nanpu River Bridge and Jinzhai Road viaduct. The collected data can be analyzed using specialized software to assess the bridge's health status and support maintenance efforts. As sensor technology advances and becomes more commercially viable, we can expect an increasing number of sensor-based solutions to be integrated into infrastructure such as bridges, rail transit, tunnels, dams, and historical buildings.
Currently, there are over 6,000 types of sensors across 10 categories, used extensively in aerospace, high-speed rail, aircraft, and other transportation systems. For example, a typical car may have over 100 sensors, while luxury vehicles can have more than 200. With the national target of having 5 million new energy vehicles by 2020, the demand for sensors is set to grow rapidly. Their application in intelligent transportation will greatly enhance the accuracy and efficiency of national transport monitoring.
In addition, sensors play a significant role in sectors like food processing, environmental monitoring, water quality control, and industrial instrumentation. Some researchers are using biomaterials to mimic human skin, creating innovative touch-sensitive sensors. Others are leveraging MEMS technology to develop micro-intelligent sensors that integrate easily into complex systems. High-precision laser technology is also being used to create laser radar systems that enable real-time perception of obstacles and environments.
In recent years, sensor innovation has seen major breakthroughs, especially in biomedicine. Wearable sensors, artificial hair sensors, moisture-detecting socks, sticker sensors, bioluminescent sensors, and smartwatch sensors are all emerging to meet the growing needs of health monitoring. These developments offer exciting possibilities for future advancements in the sensor field.
Today, as sensor technology moves toward industrialization and mass production, governments are supporting its growth. In the "Three-Year Action Plan for Promoting the Development of a New Generation of Artificial Intelligence Industry," smart sensors are highlighted as a core component. The plan aims to develop new types of smart sensors with broad market potential, including biological, gas, and pressure sensors. By 2020, it is expected that piezoelectric, magnetic, and infrared sensors will see significant improvements in performance, with pressure sensors meeting commercial standards and magnetic sensors with 1 pT resolution entering mass production.
At the same time, the sensor industry is adapting to the new economic normal, aligning with national plans such as the "13th Five-Year Plan" and initiatives for a healthier, tech-driven nation. This provides continuous inspiration and momentum for sensor innovation. Now, the challenge lies in developing sensors that match market trends and meet the requirements of these plans. For manufacturers and distributors, staying ahead of the curve, mastering core technologies, and focusing on R&D and market demands are essential to achieving long-term success in the sensor industry.
