This work presents a novel approach towards integrating electronic components with textiles, by successfully creating a fully textile-based element that is capable of detecting applied forces by variation in its resistance value. The fabrication of the device consists of a specialized siliconized conductive fabric, which is placed above and below a layer of switch fabric, which acts as a force sensor. In this paper, the effects of three different geometries are observed, as well as the washability of the device, along with tension testing. Μoreover, the device behavior is simulated as well as applied in a real-life scenario. The proposed element demonstrates a good dynamic range, high repeatability and stability, and minimal impact of washing, creating a great candidate for integration in e-textiles.

This paper reports on a fully textile electronic skin (e-skin) based on an asymmetric wool/polytetrafluoroethylene (PTFE) structure, which is fabricated through an innovative filling core yarn and weft interweaving technique, enabling self-driven contact detection and motion sensing functions. The e-skin features a three-layer woven structure, with the outer layer made of PTFE (high dielectric constant, superhydrophobic), the inner layer composed of wool (hygroscopic, skin-friendly), and a middle layer embedded with silver-plated nylon (SPN) conductive yarns forming a flexible electrode array. Benefiting from its asymmetric design, this material exhibits excellent triboelectric performance (open-circuit voltage of 37 V, short-circuit current of 58 nA), breathability (341.

Triboelectric textiles have recently garnered significant attention for their ability to detect and analyze body movements. However, the transmission of wireless signals from natural human motion via integrated triboelectric wearables has been hampered by the reliance on nontextile components, physical interface spacers, and wired connections. Here, we report a wireless biosensing triboelectric wearable system that exploits inherent microgaps within electrospun nanofibers to create a triboelectric textile, seamlessly woven into the garment at various positions.

The past decade has witnessed the rapid growth of electronic textiles with a variety of textile-based smart devices being developed. However, the development of one-dimensional conductors that exhibit both excellent mechanical and electrical properties, while being compatible with conventional textile techniques, remains a challenge. Herein, a conductive cotton yarn was constructed using liquid metal as the conductive filler and tannic acid (TA) as the immobilizing linker via a twist-assisted deposition technique, in which eutectic gallium-indium alloy (EGaIn) droplets were effectively modified on cotton plies by using TA, followed by moderate twisting.

Spurred by the global pandemic, research in health monitoring has pivoted towards the development of smart garments, enabling long-term tracking of individuals' cardiovascular health by continuously monitoring the electrocardiogram (ECG) and detecting any abnormality in the signal morphology. Many types of dry electrodes have been proposed as alternatives to gold standard Ag/AgCl wet electrodes, and they have been integrated into clothes capable of acquiring only a limited number of the different ECG traces. This limitation severely diminishes the diagnostic utility of the collected ECG data and obstructs the garment's potential for clinical-level evaluation.

The pursuit of sustainable and portable direct current (DC) energy suppliers has ignited considerable interest in tribovoltaic nanogenerators (TVNGs), devices that harvest mechanical energy from the surrounding environment. However, the predominant focus in TVNG research has centered on rigid and silicon-based semiconductors that lack flexibility and are thus ill-suited for integration into common fabrics. Herein, a fully-textile TVNG with a simple design is introduced that enables the real-time monitoring of human physiological signals.
