摘要

采用线形机械光栅与溶胶-凝胶合成的集成超声换能器相结合，制成了集成柔性超声换能器。它们可用于产生和接收引导表面和板声波，并可在高达150°C的温度下工作。初步结果表明，它们在无损评价和结构健康监测方面具有应用潜力。

High temperature guided acoustic wave transducers using mechanical gratings

Integrated and flexible guided acoustic wave transducers have been made using line shape mechanical gratings together with sol-gel fabricated integrated ultrasonic transducers at the opposite side. They can be used to generate and receive guided surface and plate acoustic waves and to operate up to 150°C. Preliminary results show the potentials of them for nondestructive evaluation and structural health monitoring applications.
