Approach of Structural Health Monitoring Based on Piezoelectric Smart Sensor

Structural Health Monitoring (SHM) aim to generate automated system for the continuous inspection, monitoring and damage identification of structural with least manpower and labor involvement. The first stage to establish a SHM system is to incorporate a level of sensing and cording capability that is reliable and possess long term stability. Smart material/sensor. Technology including the application of Piezoelectric sensors have very important capabilities of continuous monitoring and damage detecting of various physical and mechanical parameters related to health and service life of the structures. In this presented review paper piezoelectric sensor or can act as smart material which can serve both sensors and actuators which make the SHM to be active monitoring system. These advance sensing technologies are now available and progressively increasing and can be widely utilized for the SHM of civil engineering structures. In this paper the application of smart material/sensors for the continuous monitoring of structures is critically reviewed and the major focuses on the approaches of SHM based on piezoelectric sensors.
