This paper describes the early conception and latest developments of electroactive polymer (EAP)- based sensors, actuators and power sources, implemented as wearable devices for smart electronic textiles (e-textiles). Such textiles, functioning as multifunctional wearable human interfaces, are today considered relevant promoters of progress and useful tools in several biomedical field, such as biomonitoring, rehabilitation and telemedicine. This paper presents the more performing EAPbased devices developed by our lab and other research groups for sensing, actuating and energy harvesting, with reference to their already demonstrated or potential applicability to electronic textiles.

Test methods for smart or electronic textiles (e-textiles) are critical to ensure product safety and industrial quality control. This paper starts with a review of three key aspects: (i) commercial e-textile products/technologies, (ii) safety and quality control issues observed or foreseen, and (iii) relevant standards published or in preparation worldwide. A total of twenty-two standards on smart textiles – by CEN TC 248/WG 31, IEC TC 124, ASTM D13.50, and AATCC RA111 technical committees – were identified; they cover five categories of e-textile applications: electrical, thermal, mechanical, optical, and physical environment. Based on the number of e-textile products currently commercially available and issues in terms of safety, efficiency, and durability, there is a critical need for test methods for thermal applications, as well as to a lesser degree, for energy harvesting and chemical and biological applications. The results of this study can be used as a roadmap for the development of new standardized test methods for safety & quality control of smart textiles.

This study focuses on the effect of strand spacing on the tensile behavior of tri-component elastic-conductive composite yarns (t-ECCYs). The fabrication procedure of t-ECCYs was previously reported using a modified ring frame. The tensile data were analyzed with SPSS using one-way analysis of variance followed by post hoc Fisher’s least significant difference test (α = 0.05). The results demonstrate that with elevated strand spacing up to 14.0 mm, the breaking tenacity and extension at break of yarns increase, beyond which they reduce, and mean results were considered significantly different. Furthermore, a two-parameter Weibull distribution and box-whisker plot can be appropriately used to quantify the variability of tensile strength. It is evident that strand spacing plays a crucial role in influencing the structure and hence the final behavior of yarns. The shape of twisting triangle was obviously asymmetric, primarily due to modulus differences of its sub-strands in the resulting yarns. In particular, a bottom-and-right displacement of convergence points was observed with the increasing strand spacing. Finally, the electrical conductivity of t-ECCYs in various stretching states was characterized. With the superior conductivity under different stretching, t-ECCYs have tremendous prospects for wearable electronic applications. More importantly, desirable characteristics that are possibly possessed by the yarns are industrial weavability and knittability, which will pave a convenient but highly effective way for the large-scale production of wearable electronic textiles.

An increased use in wearable, mobile, and electronic textile sensing devices has led to a desire to keep these devices continuously powered without the need for frequent recharging or bulky energy storage. To achieve this, many have proposed integrating energy harvesting capabilities into clothing: solar energy harvesting has been one of the most investigated avenues for this due to the abundance of solar energy and maturity of photovoltaic technologies. This review provides a comprehensive, contemporary, and accessible overview of electronic textiles that are capable of harvesting solar energy. The review focusses on the suitability of the textile-based energy harvesting devices for wearable applications. While multiple methods have been employed to integrate solar energy harvesting with textiles, there are only a few examples that have led to devices with textile properties.
