“…However, in the latter, no further polling process is necessary due to the application of the high electric field during fabrication. However, electrospinning is more expensive and challenging, thus less applicable to mass production [164]. To collect the piezoelectric generated charge, electrodes can be coated or wrapped in core-shell structures in a sandwiched metal-insulator-metal arrangement [165].…”

Wearable devices are ideal for personalized electronic applications in several domains such as healthcare, entertainment, sports and military. Although wearable technology is a growing market, current wearable devices are predominantly battery powered accessory devices, whose form factors also preclude them from utilizing the large area of the human body for spatiotemporal sensing or energy harvesting from body movements. E-textiles provide an opportunity to expand on current wearables to enable such applications via the larger surface area offered by garments, but consumer devices have been few and far between because of the inherent challenges in replicating traditional manufacturing technologies (that have enabled these wearable accessories) on textiles. Also, the powering of e-textile devices with battery energy like in wearable accessories, has proven incompatible with textile requirements for flexibility and washing. Although current e-textile research has shown advances in materials, new processing techniques, and one-off e-textile prototype devices, the pathway to industry scale commercialization is still uncertain. This paper reports the progress on the current technologies enabling the fabrication of e-textile devices and their power supplies including textile-based energy harvesters, energy storage mechanisms, and wireless power transfer solutions. It identifies factors that limit the adoption of current reported fabrication processes and devices in the industry for mass-market commercialization.

“…Park et al introduced a novel poling-free spinning process for manufacturing piezoelectric yarns that rotated and expanded nanofibers to form piezoelectric yarns. 18 The results indicated that when made using 1 MPa and 0.5 Hz, the piezoelectric voltage reached 500-600 mV, and the piezoelectric yarns could be applied to sensors or nanogenerators; however, pure nanofibers have limited applications owing to poorer mechanical properties. Ji et al enwrapped conductive yarns in piezoelectric nanofibers in order to make core-sheath piezoelectric nanofiber yarns.…”

Piezoelectric textiles have earned widespread acceptance in the application of wearable sensors owing to the stabilized energy conversion properties, high sensitivities and steady mechanical properties. In this study, silver-coated nylon yarns are used as a core with poly(vinylidene fluoride) nanofibers as a wrap material, forming piezoelectric wrapped yarns. The effect of spinning process parameters on the structure and crystallinity of the piezoelectric yarn is investigated through studying the mechanical properties, ⊎-phase ratio, crystallinity and piezoelectric properties. The results indicate that the crystallinity of the wrapped yarn reaches 49.57% in this experiment, and when used for piezoelectricity, the piezoelectric voltage constant can reach up to 0.4323 mV m N −1 . The wrapped yarns possess good softness and structural advantages of the sensing layer and thus show a great variety of application potential, such as in wearable and flexible sensors.
