Summary: Surface acoustic wave (SAW) devices utilizing graphene-based interdigital transducers (IDTs) have been developed to generate SAWs with a frequency of 100 MHz in microfluidic devices, allowing precise manipulation of microparticle solutions by acoustic streaming and mixing of liquids. Due to the negligible mass loading of the piezoelectric surface by graphene, the SAWs generated by these devices do not exhibit frequency shift commonly observed with metal IDTs.

Summary: A flexible surface acoustic wave (SAW) strain sensor based on a 100 μm thin langasite substrate is proposed, with a linear strain range of 1-1800 με and strain sensitivity of 44.68 Hz/με at room temperature. The sensor is affected by temperature at a fixed strain, and changes in temperature or strain cause variations in the measured frequency. To accurately measure strain in complex environments, the interference of temperature needs to be eliminated, and the intercept and slope are extracted from the strain-frequency curves at different temperatures for accurate estimation.

Summary: We present theoretical and experimental results on the losses and confinement of spin waves in a multilayer structure consisting of a Ferro-magnetic layer, a Normal Metal layer, an Air layer, and a Ferrite layer. We show that inserting a screening Normal Metal layer between the SW waveguide and the ferromagnetic layer can significantly reduce the SW losses. Moreover, we find that the SW amplitude increases within the air gap between the Ferrite film and the Normal Metal layer when the gap satisfies the relation kd =1, where k is the SW wavenumber. The power flow density at the Ferrite/Air interface is maximal when the air gap is equal to a quarter wavelength of the SW.
