Acoustic impedance enables many interesting acoustic applications. However, for gas sensing is rare and difficult. Here we introduce a micro-nano surface wave (SAW) chip based on the effect to achieve ultra-fast wide-range sensing. We theoretically established relationship between load SAW attenuation, analyzed influence of propagation loss under different gas/humidity media. Experimental measurements reveal that differences in generated by gases trigger can (0-100 v/v%) monitoring, with response recovery speeds reaching sub-second levels (t90 < 1 s, t10 0.5 s) detection limit ~1 v/v%. This capability also be perfectly utilized human respiratory accurately reflecting status, frequency, intensity. Consequently, provides new solution in-situ leaks precise monitoring respiration.

Total acoustic transmission between water and air is modelled using a purely solid interface comprising two elastic plates separated by periodically spaced ribs. The frequency of full depends only on, inversely proportional to, the areal density plate facing air. total also requires specific dependence rib spacing on bending stiffness plates. These relations are result an explicit analytical solution for transmitted reflected waves combined with asymptotic approximations based small parameter defined air-to-water impedance ratio. Surprisingly, effect almost independent angle incidence, even though conditions predicated normal incidence. Parametric studies performed to examine bandwidth Q-factor transmissivity.

Due to the significant impedance mismatch between water and air, two types of pipeline silencers designed for same target frequency with different filling materials often have significantly thickness. This increases difficulty in designing multiple pipelines narrow spaces. The paper reports a metamaterial design paradigm based on Helmholtz cavity low-frequency sound absorption both air water-filled pipelines. An asymmetric coupled resonators is proposed reduce impact noise By coupling mode reflection mode, thickness 71 mm achieves 95.6% at 403 Hz. tunable absorbing performance broadband confirmed by finite element simulation.

Transmission enhancement of sound waves across the interface between media with different impedances is a classical problem in acoustic communication, for instance case water-air interface. Different strategies, including bubble-embedded metasurfaces or impedance-matched metamaterials, have been developed to render transparent. Transmedia wave up now either broadband incorporating customized wavefront manipulation. In this paper, we explore use transformation acoustics and gauge realize both goals simultaneously. Transformation first argued provide lossless transmedia enhancement, although at expense adapting cross section respect power-flow conservation. It specifically proven that gradient anisotropic metamaterial provides perfect transmission two dimensions steering allowed as well. Gauge theory then adapted from elasticity one-dimensional via Willis-like metamaterial. Finally, transformations are combined together implement focusing The lens designed by proposed method achromatic. This paper expected alternative solutions communication.

Abstract The transformation of acoustic impedance (AI) in different media regulates the transmission and reflection characteristics waves between media, thus enabling many interesting applications. Here we introduce for first time a surface wave (SAW) chip based on AI effect, which utilizes its piezoelectric effect unique interdigital transducer to excite mechanical propagating along crystal, it features high sensitivity surface-loaded such as gases humidity changes due SAW energy being localized surface. On this basis, theoretically established relationship load propagation loss, analyzed influence loss under gas/humidity using mass conservation ideal gas state equations. Experimental measurements chips reveal that differences generated by trigger signals, can achieve wide-range (1-100 v/v%) monitoring, with fast response recovery speeds reaching sub-second levels (t90<1 s, t10<0.5 s). This capability also be perfectly utilized human respiratory accurately reflecting status, frequency, intensity. Therefore, sensing method proposed work provide new solution in-situ detection leaks precise monitoring respiration.
