Abstract 
As an important branch of modern sensor technology, MEMS sensors have shown wide application prospects in consumer electronics, automotive electronics, medical health, aerospace and other fields by virtue of their advantages of miniaturization, integration and high sensitivity. This paper discusses the design and application of micro-electro-mechanical system (MEMS) sensor, analyzes its advantages and challenges in practical application from its basic principle, manufacturing technology and performance characteristics, and looks forward to its future development trend. Microelectromechanical system (MEMS) sensor is a kind of miniaturized sensor which integrates micromechanical structure with microelectronic circuit. It uses advanced micromachining technology to integrate sensors, actuators, signal processing circuits, etc. on a tiny chip to achieve high performance, low power consumption and miniaturization of the sensor. With the progress of science and technology and the demand of the market, MEMS sensors are more and more widely used in various fields. The design of MEMS sensor involves many aspects such as material selection, structure design and manufacturing process. First of all, it is necessary to select suitable materials, such as silicon, me tal, ceramics, etc., to meet the performance requirements of the sensor. Secondly, through the structural design, the sensor can achieve the performance characteristics of high sensitivity, high stability and low power consumption. Finally, the sensor is manufactured using advanced manufacturing processes, such as lithography, etching, thin film deposition, etc. MEMS sensors are widely used in various fields. In the field of consumer electronics, MEMS sensors are used to realize motion detection, posture recognition and other functions of mobile phones, tablets and other devices. In the field of automotive electronics, MEMS sensors are used to achieve vehicle safety control, navigation and positioning functions. In the field of medical health, MEMS sensors are used to realize non-invasive fetal heart detection, blood pressure monitoring and other medical auxiliary devices; In the aerospace field, MEMS sensors are used to achieve attitude control, navigation and positioning of aircraft. Although MEMS sensors have many advantages, they also face some challenges in practical applications, such as the complexity of the manufacturing process and the improvement of performance stability. In the future, with the progress of science and technology and the demand of the market, MEMS sensors will develop in the direction of higher performance, lower power consumption and smaller size, and at the same time, more attention will be paid to the integration with other technologies, such as the Internet of Things, artificial intelligence, etc., to achieve a wider range of applications.
