In today's rapidly developing technology, sensor technology has become a key support in many fields. Among them, quartz flexible acceleration sensors play an indispensable role in multiple industries due to their unique performance advantages. Its three main uses are reflected in the aerospace, automotive industry, and oil exploration fields.

Recently, with the acceleration of industrial intelligence, stress wave sensors, as a key technology for equipment condition monitoring, are receiving increasing attention. This type of sensor can capture stress wave signals in real-time during device operation, providing accurate "diagnosis" for the health status of the equipment, effectively preventing faults, and improving the safety and stability of industrial production.

In the current era of rapid technological development, sensors, as key components for obtaining information, are widely used in many fields such as industry, healthcare, and automobiles. Chinese sensor companies are actively exploring ways to break through and innovate in the global competitive landscape, striving to enhance their competitiveness and achieve leapfrog development.

Lidar (Laser Detection and Ranging) is an advanced sensing technology that calculates target distance by emitting laser pulses and measuring their return time. It is widely used in fields such as autonomous driving, robotics, and industrial automation. With the development of technology, LiDAR has undergone an evolution from mechanical to semi-solid state and then to solid state. This article will delve into the working principles, characteristics, and applications of solid-state and semi-solid state LiDAR.

For many years, gas sensors have attracted great interest due to their applications in various fields such as medical diagnosis, environmental monitoring, worker safety, and food quality control. For these applications, ideal gas sensors should have high sensitivity and selectivity for tracking targets, fast response/recovery capabilities, low energy consumption, and cost-effectiveness.

In today's rapidly developing technology, our lives are filled with various smart devices, from smartphones to smartwatches, from automotive electronic systems to smart home devices. The reason why these devices can achieve such rich functions is inseparable from a magical technology - MEMS (Micro Electro Mechanical System). MEMS devices, with their unique advantages, are quietly changing our lives.
