Materials and Wireless Microfluidic Systems for Electronics Capable of Chemical Dissolution on Demand (Adv. Funct. Mater. 92015)

On the design of capacitive sensors using flexible electrodes for multipurpose measurements.

This article evaluates the potential of capacitive measurements using flexible electrodes to access various physical quantities. These electrodes are made of a thin metallic film, typical thickness 0.2 microm, evaporated on a plastic substrate. Their large flexibility enables them to be mounted in complex geometries such as curved surfaces. In the configuration of planar condensers, using a ver...

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.

Capacitive soft strain sensors via multicore-shell fiber printing.

A new method for fabricating textile integrable capacitive soft strain sensors is reported, based on multicore-shell fiber printing. The fiber sensors consist of four concentric, alternating layers of conductor and dielectric, respectively. These wearable sensors provide accurate and hysteresis-free strain measurements under both static and dynamic conditions.

Spoofing Capacitive Fingerprint Sensors

This white paper discusses methods and findings from one of Novetta’s many approaches to vulnerability assessment: the fabrication of non-gelatinous artifacts for capacitive fingerprint sensors. We present methods of evaluating artifact performance relative to that of live presentations and gummy fingerprint artifacts. Two sets of artifacts are comprised of latex face paint or acrylic fabric pa...
