Textiles can have valuable functions in terms of measurement, detection and communication when they are incorporated into functional electronic devices. However, the additional electric circuits limit the flexibility and extensibility, making the wearers uncomfortable and the manufacturing difficult. Therefore, in this study, conductive elastic knits are made of metallic yarns and expected to be used as wearable electronic textiles. In order to retain the flexibility of knits, a crochet machine with jacquard equipment is used to create knit patterns as electric circuits. Regardless of whether it is single-twisted yarn, double-twisted yarn, single-wrapped yarn, or double-wrapped yarn, the metallic wires can be completely covered in polyester filaments. Variations in twist numbers of conductive yarns or knit patterns are beneficial to the tensile strength with a maximum increment of 14%, and changing twist numbers of conductive yarns or knit patterns have a positive influence on the air permeability with a maximum increment of 24%. According to the results of the electric circuit stability test, using double-covered yarns ensures the knits a stabilized electric circuit regardless of the knit pattern.

To achieve reliable flexibility and acceptable transparency for integrated electronics, the power supply sources of these devices have to meet the requirement of flexibility and transparency. Herein, we developed a facile and non-toxic way to manufacture all-solid-state supercapacitors with high capacitive performance, transparency and flexibility. The as-prepared g-C3N4 nanowires are distributed in Polyvinyl Alcohol (PVA) and Poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) solution, transparent film could be formed by vacuum filtration. The g-C3N4 nanowires provide pseudocapacitance and PVA and PEDOT:PSS matrix provides bendable and stretchable ability. The g-C3N4/PVA electrode achieves a specific areal capacitance of 3.51[Formula: see text]mF[Formula: see text]cm[Formula: see text] with transparency of 85%, and that of g-C3N4/PVA/PEDOT:PSS is 5.32[Formula: see text]mF[Formula: see text]cm[Formula: see text] with transparency of 72%. The facile process provides a reasonable architecture for the preparation of a variety of flexible, transparent and wearable electronic devices. The flexible and transparent devices show an instant response to the finger bending with the capacitance change of more than 25%, which provides the possibility for fabricating smart flexible device to monitor human health and motion detection.

This paper presents research into a user-friendly electronic sleeve (e-sleeve) with integrated electrodes in an array for wearable healthcare. The electrode array was directly printed onto an everyday clothing fabric using screen printing. The fabric properties and designed structures of the e-sleeve were assessed and refined through interaction with end users. Different electrode array layouts were fabricated to optimize the user experience in terms of comfort, effectivity and ease of use. The e-sleeve uses dry electrodes to facilitate ease of use and the electrode array can survive bending a sufficient number of times to ensure an acceptable usage lifetime. Different cleaning methods (washing and wiping) have been identified to enable reuse of the e-sleeve after contamination during use. The application of the e-sleeve has been demonstrated via muscle stimulation on the upper limb to achieve functional tasks (e.g., hand opening, pointing) for eight stroke survivors.
