A Review of Smart Sensor Technology and Its Aerospace Applications

With the rapid development of the aerospace industry and the introduction of the concept of smart aerospace,the demand for smart sensors in the aerospace field is increasing day by day.Firstly,provide an overview of the definition and characteristics of smart sensors.Secondly,analyze the development stages of smart sensors.Finally,taking four typical application scenarios as examples,this article elaborates on the application and research status of smart sensor technology in the aerospace field.Analysis shows that intelligent sensor technology plays an important role in four aspects:structural detection and early warning of rocket bodies,monitoring and fault prediction of space engine status parameters,monitoring of space station structural safety and physiological indicators of astronauts,environmental perception of extraterrestrial probes,and autonomous planning.Based on this,the future development direction of smart sensor technology is discussed in combination with the practical needs of the aerospace field.
