Ultrasonic monitoring is one of the most important tools in the field of structural health monitoring (SHM). The main goal of this paper is to provide a comprehensive review of the recent advances and achievements in ultrasonic wave SHM of buildings and bridges built with concrete and steel materials and the types of sensors used in these structures. In this paper, the parameters affecting the monitoring process, including the type of damage, the type of ultrasonic wave, and the type of sensor, are reviewed. The sensor devices used to transmit and receive ultrasonic waves, like lead zirconate titanate, electromagnetic acoustic transducer, and others and their applications in building and bridges, are discussed. The limitations of each type of theses sensors are highlighted. Finally, conclusions are drawn and recommendations for an improved sensor overcoming the shortcomings of the current sensors are given.
