“…The aim was to minimize the requirements about external components and the overall complexity, at the cost of reduced spectral purity. Indeed, they are intended for converting the numeric stream from FSK and/or PSK modulators, actually generating a constant envelope sinusoidal (analog) signal [37]. …”

“…A waveform generator 11 (33500B series, Keysight) was applied as a pulse generator to excite the ultrasonic sensor to produce the corresponding ultrasonic pulse wave. A digital oscilloscope 12 (RTB2000, Rohde & Schwarz) was used to collect the ultrasonic signal of the sensor and upload it to the computer for further analysis.…”

The extensive use of reinforced materials in the construction industry has raised increased concerns about their safety and durability, while corrosion detection of steel materials is becoming increasingly important. For the scientific management, timely repair and health monitoring of construction materials, as well as to ensure construction safety and prevent accidents, this paper investigates corrosion detection on construction materials based on piezoelectric sensors. At present, the commonly used corrosion detection methods include physical and electrochemical methods, but there are shortcomings such as large equipment area, low detection frequency, and complex operation. In this study an improved piezoelectric ultrasonic sensor was designed, which could not only detect the internal defects of buildings while not causing structural damage, but also realize continuous detection and enable qualitative and quantitative assessment. Corrosion detection of reinforced building materials with piezoelectric sensors is quick and accurate, which can find hidden dangers and provide a reliable basis for the safety of the buildings.
