The purpose of this study is to analyze the state-of-art knowledge of the use of energy harvesters (EHs) to power the wearables of clothing. The study discusses some examples of clothing with incorporated different types of EHs, harvesting energy from body movement (based on piezoelectric, electromagnetic, and electrostatic phenomena) from temperature differences, as well as from solar radiation. In the performed analysis, particular attention was focused on the design of EHs, their principle of operation, advantages, disadvantages, and restrictions on use. Low energy requirements of wearable electronics (e.g., sensors and diodes) implemented to clothing indicate the possibility of using miniaturized EHs as a power source for such elements. Each of the discussed EH has both disadvantages and advantages. Therefore, the selection of EH should be preceded by a detailed analysis of the conditions of the garment use, its destination, the user’s physical activity, and the energy needs of the electronic devices incorporated in clothing. Despite a variety of research studies aimed at developing new EH, relatively few of them concern their implementation in the structure of clothing and tests of their functionality in the foreseeable conditions of use. In view of the above, these issues have been addressed in this publication based on the available literature.

This work presents a simple and reliable method for directly generating polyvinylidene fluoride (PVDF) nanofibers with secondary surface morphology (e.g., porous surfaces, rough surfaces, grooved surfaces, and interior porosity) by using single/binary solvent systems and relative humidity. We clarified the mechanisms responsible for the formation of these morphologies by systematically exploring the molecular interactions among the polymer, solvent(s), and water vapor. Our results proved that the formation of secondary surface morphology needed the presence of water vapor, a non-solvent of the polymer, at an appropriate level of relative humidity. The formation of secondary surface morphology was dependent on the speed of evaporation of the solvent(s) (ACE, DMF, and their mixtures), as well as the inter-diffusion and penetration of the non-solvent (water) and solvent(s). The results of N2 physical adsorption-desorption isotherms showed that the macro-porous fibers (> 300 nm) exhibited the highest specific surface area of 23.31 ± 4.30 m2/g and pore volume of 0.0695 ± 0.007 cm3/g, enabling the high oil absorption capacities of 50.58 ± 5.47 g/g, 37.74 ± 4.33 g/g, and 23.96 ± 2.68 g/g for silicone oil, motor oil, and olive oil, respectively. We believe this work may serve as guidelines for the formation of different structures of macro-porous, rough, and grooved nanofibers with interior porosity through electrospinning.Electronic supplementary materialThe online version of this article (10.1186/s11671-018-2705-0) contains supplementary material, which is available to authorized users.

“…Such materials are generally named as "smart materials", with the ongoing research mostly focusing on enhancing their efficiency. However, for wearable energy harvesters, the thermophysiological properties of such structures are of equal importance and can potentially dictate their most appropriate application and further uptake as apparel or technical fabrics [22,23].…”

Evaluating the fabric performance and anti-bacterial properties of 3-D piezoelectric spacer fabric The increasing need of on-demand power for enabling portable low-power devices and sensors has necessitated work in novel energy harvesting materials and devices. In a recent work (Soin et al., Energy Environ. Sci. 2014, 7(5), 1670), we demonstrated the production and suitability of 3-D spacer all fibre piezoelectric textiles for converting mechanical energy into electrical energy for wearable and technical applications. The current work investigates the textile performance properties of these 3-D piezoelectric fabrics including porosity, air permeability, water vapour transmission and bursting strength. Furthermore, as these textiles are intended for wearable applications, we have assessed their wear abrasion and consequently provide surface resistance measurements which can affect the lifetime and efficiency of charge collection in the piezoelectric textile structures. The results show that the novel smart fabric with a measured porosity of 68% had good air (1855 l/m 2 /s) and water vapour permeability (1.34 g/m 2 /day) values, good wear abrasion resistance over 60,000 rotations applied by a load of 12 kPa and bursting strength higher than 2400kPa. Moreover, the antibacterial activity of 3-D piezoelectric fabrics revealed that owing to the use of Ag/PA66 yarns, the textiles exhibit excellent antibacterial activity against not only gram negative bacteria E. coli but they are also capable of killing antibiotic methicillin resistant bacteria S. aureus.
