This paper reviews the applications of in-situ health monitoring and prognostic sensors with the focus on those in electronic systems. It provides an insight into the issues of utilizing in-situ sensors in electronic systems for health monitoring and prognostics. Those issues are discussed in comparison to those for mechanical systems and structures. This paper also introduces a physics-of-failure based life- consumption monitoring methodology for the health monitoring and life prediction of electronic systems.
Key words: in-situ sensor, health monitoring and prognostics, electronics reliability
