PIEZO-BASED TECHNIQUES FOR CORROSION DETECTION AND OVERALL HEALTH MONITORING OF AEROSPACE STRUCTURES

Corrosion poses a significant threat to aerospace structures, leading to safety hazards and operational failures.This review briefly discusses the state of art in corrosion monitoring techniques, focusing on the significance of piezoelectric transducer-based structural health monitoring (SHM) technologies and their applications in the aerospace industry.Based on the recent studies, we find that the piezoelectric material-based techniques are superior among the other methods in terms of their efficiency, cost-effectiveness, and structural simplicity.The importance of structural health monitoring and the role of advanced sensors in mitigating corrosion risks are highlighted.
