When materials are uniaxially compressed, they typically expand in directions orthogonal to
the applied load. Here, we exploit buckling to design a new class of three dimensional …

The delivery of macromolecules via the gastrointestinal (GI) tract remains a significant
challenge. A variety of technologies using physical modes of drug delivery have been …

Most conventional materials expand in transverse directions when they are compressed
uniaxially resulting in the familiar positive Poisson's ratio. Here we develop a new class of …

A series of analytical relationships is presented to predict the mechanical properties and
response of open three-dimensional Voronoi tessellation of face-centered cubic structures …

The proposed structure comprises an array of elastomeric helices that can be easily
stretched in the axial direction (see Figure 1). In the undeformed configuration the helices …

The gut-brain axis, which is mediated via enteric and central neurohormonal signaling, is
known to regulate a broad set of physiological functions from feeding to emotional behavior …

We combine numerical simulations and experiments to design a new class of reconfigurable
waveguides based on three-dimensional origami-inspired metamaterials. Our strategy …

We highlight the effect of structural hierarchy and deformation on band structure and wave-
propagation behavior of two-dimensional phononic crystals. Our results show that the …

The evaluation of the tone and contractile patterns of the gastrointestinal (GI) tract via
manometry is essential for the diagnosis of GI motility disorders. However, manometry is …

Falls and subsequent complications are major contributors to morbidity and mortality,
especially in older adults. Here, by taking inspiration from claws and scales found in nature …
