Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Dielectric elastomers (DEs) are a type of multifunctional materials with salient features that
are very attractive in developing soft, lightweight, and small-scale transducers and robotics …

Dielectric elastomers are active materials that undergo large deformations and change their
instantaneous moduli when they are actuated by electric fields. By virtue of these features …

Active tuning of frequency bandgaps has received significant attention in the recent past. To
this end, soft compressible phononic composites have indicated great promise owing to their …

The research interest on phononic crystals now takes a new turn towards the acoustic/elastic
analogies of the quantum concepts, eg, the quantum Hall, quantum spin Hall and quantum …

Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit
anomalous wave propagation properties through artificial design of topologies or lattice …

This paper presents an electromechanical analysis of the nonlinear static response and the
superimposed small-amplitude wave characteristics in an infinite periodic compressible …

The operating frequency range of passive topological phononic crystals is generally fixed
and narrow, limiting their practical applications. To overcome this difficulty, here we design …

Membrane-type metamaterials have shown a fantastic capacity for manipulating acoustic
waves in the low frequency range. They have the advantages of simple geometry, light …

Soft electroactive materials can undergo large deformation subjected to either mechanical or
electrical stimulus, and hence, they can be excellent candidates for designing extremely …
