The concept of Structural Health Monitoring of concrete structures under the seismic load condition has recently made the more attention in the research community of earthquake and structural engineering. Due to destruction of expensive structures, this research makes the attraction of researchers who are doing their research work in the field of damage detection based on the piezoelectric smart sensor. In this review work, the way of post seismic damage detection of structure using the smart aggregate a piezoelectric – based device which have embedded in the reinforced concrete structure and the way to monitor their damage after the effect of an earthquake. During this presented review, a study work has conducted to describe the methodology that has employed to detect the postseismic damage of concrete structure and the methodology of electro-mechanical impedance sensor that has been used for the health monitoring of the structure. The PZT which was embedded in the structure during the construction and the variation in the impedance of the sensor before and after the seismic attacks were extracted as the damage sensitive features are utilized to detect the area of damage. This technique is very important in non –destructive testing and have also tried to attract the attention of the reader. After analyzing the damage of the structure through the attack of an earthquake, the required repair and serviceability can be provided to structure to sustain the structural failure.
