Summary:Purpose - To provide an overview of self-validating sensor technology for researchers and engineers which can help them understand the concept and recent developments of this research area.Design methodology approach - The concept of self-validating (SEVA) sensors, including definition, output parameters and requirement of SEVA sensors are introduced. The differences between SEVA sensors and traditional sensors are given from which we can see many advantages of SEVA sensors. The principium of SEVA sensors is presented by the functional architecture. The research development of SEVA sensors is introduced in two aspects: research development of sensor fault diagnosis and signal reconstruction and research development of SEVA sensor hardware.Findings - Summarizes the methods for sensor fault diagnosis and signal reconstruction in the research of SEVA sensors, and the development steps of SEVA sensor hardware. Indicates the shortages and problems of current research and gives our research and ideas to solve these problems.Originality value - This paper provides a detailed description and research information of self-validating sensor technology for those who want to know and research on this area.
