Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

Acoustic Switches: Harnessing Deformation to Switch On and Off the Propagation of Sound (Adv. Mater. 8/2016).

Isosurfaces of sound waves traveling through an architected material proposed by K. Bertoldi and co-workers on page 1631 are depicted. The material comprises a square array of elastomeric helices in background air and acts as an on/off acoustic switch. It is characterized by frequency ranges of strong wave attenuation (bandgaps) in the undeformed configuration. Upon deformation, the initial ban...

Nanoelectrodes: Large-Scale Nanoelectrode Arrays to Monitor the Dopaminergic Differentiation of Human Neural Stem Cells (Adv. Mater. 41/2015).

A large-scale homogeneous nanocup-electrode array (LHONA) capable of noninvasive real-time monitoring of dopamine generation from human neural-stem-cell-derived midbrain neurons is described by J.-W. Choi, K.-B. Lee, and co-workers on page 6356. LHONA, fabricated through sequential laser interference lithography (LIL), is a conductive cell-culture platform that is extremely important for electr...
