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.

Flexible Devices: Extremely Stable Current Emission of P‐Doped SiC Flexible Field Emitters (Adv. Sci. 1/2016)

Three-dimensional, flexible nanoscale field-effect transistors as localized bioprobes.

Nanoelectronic devices offer substantial potential for interrogating biological systems, although nearly all work has focused on planar device designs. We have overcome this limitation through synthetic integration of a nanoscale field-effect transistor (nanoFET) device at the tip of an acute-angle kinked silicon nanowire, where nanoscale connections are made by the arms of the kinked nanostruc...

Modular Kirigami

Modular Kirigami is here defined as the symmetric assemblage, with artistic intent, of multiple copies of cut paper shapes. Intricate examples with icosahedral symmetry are presented. These consist purely of interlocked flat pieces of paper, with no folding and no adhesives.
