Lamb Wave Directional Sensing with Piezoelectric Fiber Rosette in Structure Health Monitoring
Shock and Vibration, 2019 Directional piezoelectric sensors can detect the Lamb wave propagation direction to locate damage in structural health monitoring (SHM). The directivity of the round piezoelectric fiber is exploited with a 0°/45°/90° rosette configuration to acquire ...

Global Winds Shape Planetary‐Scale Lamb Waves
Geophysical Research Letters, 2023 In 2022, the Hunga volcano eruption in Tonga generated atmospheric pressure waves that propagated globally and produced tsunamis in all the world's oceans.

A self-assembled metamaterial for Lamb waves [PDF]
Applied Physics Letters, 2015 We report the design and characterization of a self-assembled, locally resonant acoustic metamaterial for Lamb waves, composed of a monolayer of 1.02 μm polystyrene microspheres adhered to a 1.27 μm thick free-standing silicon membrane. A laser-induced transient grating technique is used to generate Lamb waves in the metamaterial and to measure its ...

Modes Control of Lamb Wave in Plates Using Meander-Line Electromagnetic Acoustic Transducers
Applied Sciences, 2020 The multimode and dispersion characteristics of Lamb waves make them difficult to apply to nondestructive evaluation. This paper presents a paired configuration of a meander-line coil electromagnetic acoustic transducer (EMAT) to generate a single-mode ...

Advanced Science, EarlyView.Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

The Suitability of Using 3D PLA Printed Wedges for Ultrasonic Wave Propagation
IEEE Access, 2020 This work studies the suitability of using 3D printed PLA wedges made through additive manufacturing to propagate Lamb waves in plate structures instead of using rather more expensive commercial wedges.
