With the innovation of fabrication processes for piezoelectric thin films and coatings, piezoelectric sensorsp properties are optimized for a wider application area and prospect. Combined with research hotspots and current situation, the dynamic monitoring principle of piezoelectric sensing is briefly described, and the research advances of bonded piezoelectric sensing, embedded piezoelectric sensing and surface coated Piezoelectric sensing in structure intelligent monitoring are reviewed. From the perspective of different preparation processes, different types of surface coated piezoelectric sensors are introduced respectively. The advantages and disadvantages of those three Varieties of sensors are summarized and the fabrication procedures for surface coated piezoelectric sensors are discussed. Finally the future application prospect and development direction are proposed.
