Mapping strain fields in visually opaque structural compositesfor which failure is often sudden, irreparable, and even catastrophicrequires techniques to locate and record regions of stress, fatigue, and incipient failure. Many composite materials are transparent in the terahertz spectral region, but ...
Sensing action in any device follows an underlying principle by virtue of the material or the architecture of the device. A feasible mechanism of device most commonly used has either a piezoelectric, resistive or capacitive behavior. These have a sensing methodology for each of the device architectu...
Recently, a new wave of 3D-printed structures is becoming appealing: the fabrication of smart objects with embedded sensors. The key enabler for the fabrication of smart objects is the additive manufacturing of conductive materials used to create embedded sensing systems. Due to the possibility of ...
Figure 1. (a) Picture of a textured soft elastomeric capacitor (SEC) and (b) a schematic of a corresponding SEC of thickness h and a section of the electrode layer with electrode area l× w (black layer). The sensing principle of the SEC is based on a measurable change in capacitance...
