Abstract

Structural health monitoring (SHM) of automobiles is important to detect damage at an early stage and prevent failures. This paper provides a comprehensive review of using piezoelectric sensors for SHM in automobiles. Firstly common damage types in automobile structures are introduced. Thereafter, the operating principles, modeling, and application of piezoelectric sensors for damage detection are reviewed. Different sensor configurations such as piezoelectric ceramics, piezoelectric wafer active sensors (PWAS), and piezoelectric fiber composites are evaluated. The use of piezoelectric sensors with other SHM techniques like acoustic emission and guided waves is also discussed. Finally, the current challenges and future research directions in this field, including optimizing sensor placement, environmental temperature effects, and integrated SHM systems are summarized. The tables provided give an overview of typical applications, advantages and limitations of different piezoelectric sensors, and comparisons with other popular SHM techniques. This review covers the latest progress and demonstrates the effectiveness of piezoelectric sensors for automobile SHM
