This paper focuses on the development status of MEMS sensor technology
biosensors
environmental sensors
and intelligent sensor technology from 2023 to 2025
and systematically elaborates on the application progress of sensor technology in five major fields:industrial automation
medical and health
smart cities
smart agriculture
aviation and commercial aerospace.From the two dimensions of technical development status and scenario application
the study concludes that the development of sensor technology focuses on four directions:new materials
process technology
algorithms and intelligent processing
and multi-sensor fusion.The research results have important reference significance for technology research and development and industrial layout in the sensor field.
