Article Synopsis
- High-temperature (HT) ultrasonic transducers are gaining attention for monitoring structural health in extreme conditions, particularly for pipelines.
- The article details the development of a high-temperature piezoelectric wafer active sensor (HT-PWAS) using Y-cut gallium phosphate to enable torsional guided wave modes at temperatures up to 600 °C.
- Tests on the sensor included electromechanical impedance spectroscopy and laser Doppler vibrometry, which validated a model for its electromechanical behavior, aiming to improve guided-wave monitoring of pipelines under harsh environments.
