“…The contour of the normalized resistance plot (DR/R) intimately follows that of the stress-strain plot. This feature has already been reported by the authors for similar sensors developed from nanocomposites [9,10,[50][51][52][53][54]. The ability of the sensors to map the deformation of composites with high fidelity makes them ideally suited for the purpose of structural health monitoring (SHM) as against traditional strain gauges.…”

Graphene nanocomposites are constantly being explored for their applicability in the growing domain of strain monitoring (Jing et al. in Chin Phys B 22(5):057701, 2013) for real-time health and integrity assessment of structural parts. Strain gauges were manufactured by incorporating conductive graphene nanoplatelets (GNPs) in insulating polystyrene matrix by varying filler concentrations. Initial measurements showed that the resistance of these gauges decreases with increasing content of GNPs. For structural health monitoring (SHM) applications, these gauges were pasted on laminated glass fiber composite substrate. The specimens with integrated gauges were tested under monotonic tensile loading. The piezoresistive response of gauges was observed and registered as a means to detect strains in the composite specimens. The results presented in this paper demonstrate SHM capabilities of these smart strain gauges.

“…More and more heating fabrics and heating garments were springing up, especially in recent years. Stainless steel yarns with comb structure were arranged in cotton yarn fabric during the weaving process to acquire heating element . Hao et al integrated superfine silver filament in woven fabric and fabricated a resistance adjustable flexible heating fabric, experimental results showed strong positive linear correlations are between rated power and utmost ascending temperature of flexible heating fabric and between power consumption and presetting equilibrium temperatures of flexible heating fabric.…”

A novel method for fabricating flexible and waterproof heating membranes was presented in this study, nano-SiC/thermoplastic polyurethane (TPU) hybrid membranes has been successfully prepared by pouring modified nano-SiC/TPU solution into a mold with 0.05 mm silver filaments. Nano-SiC particles were modified using silane coupling agent, subsequently, were dispersed evenly in the solvent, average diameter of nano-SiC particles could reach 180.4 nm. Fourier Transform Infrared spectra showed organo-functional groups were grafted on surface of nano-SiC by covalent bond. TPU membrane with 10 wt % nano-SiC had the highest decomposition temperature, and maximum stress. Thermal conductivity and the surface equilibrium temperature under the same loaded voltage of membranes ascended with increasing of nano-SiC content. Flexible, waterproof nano-SiC/TPU heating membranes have wide application prospect in active warming garments and other fields required flexible heating elements.

This paper presents a study conducted on the thermo-mechanical properties of knitted structures, the methods of manufacture, effect of contact pressure at the structural binding points, on the degree of heating. The test results also present the level of heating produced as a function of the separation between the supply terminals. The study further investigates the rate of heating and cooling of the knitted structures. The work also presents the decay of heating properties of the yarn due to overheating. Thermal images were taken to study the heat distribution over the surface of the knitted fabric. A tensile tester having constant rate of extension was used to stretch the fabric. The behavior of temperature profile of stretched fabric was observed. A comparison of heat generation by plain, rib and interlock structures was studied. It was observed from the series of experiments that there is a minimum threshold force of contact at binding points of a knitted structure is required to pass the electricity. Once this force is achieved, stretching the fabric does not affect the amount of heat produced.
