Acoustics articles from across Nature Portfolio

Voice communication faces challenges from noise and obstructions. Here, the authors present a flexible PMUT-based wearable sensor, focusing on signal capture, noise resistance, and applications in HMI, IoT, and speech disorder assistance.

Bound states in the continuum (BICs) are captivating for their ability to stay isolated from radiative channels. The authors report on elastic BICs formed through multiphysics-acoustoelastic coupling, which enable the generation of exceptionally high-quality factors.

Topological edge states frequently arise in classical wave systems, often linked to explicit or hidden symmetries. Here, the authors study a spring-mass model with hidden symmetries revealed in deformation coordinates, where 1D and 2D spinner lattices are explored to show robust, distinct edge profiles, enabling advanced designs.

Moiré quasicrystals exhibit many exotic phenomena. Here, the authors report an acoustic moiré quasicrystal that not only achieves a localization-delocalization transition, but also enables wave propagation shifting from diffusion to canalization or localization.

An article in Nature Communications uses mechanophores to visualize shockwaves, induced by high-velocity impacts, in a block copolymer.

Acoustic and optical traps enable contactless manipulation of objects, but trapping has been limited to homogeneous environments. Wavefront shaping now extends this versatile manipulation tool to dynamic and disordered media.

Unreleased acoustic resonators fabricated in commercial fin-field-effect-transistor technology could be used in multigigahertz signal processing.

The phase, frequency and amplitude of gigahertz acoustic waves can be electrically controlled in a lithium niobate waveguide at millikelvin temperatures.

The introduction of crystalline defects experimentally reveals elusive signatures of topological phenomena in acoustic metamaterials.
