Wearable electronics are emerging as a platform for next-generation, human-friendly, electronic devices. A new class of devices with various functionality and amenability for the human body is essential. These new conceptual devices are likely to be a set of various functional devices such as displays, sensors, batteries, etc., which have quite different working conditions, on or in the human body. In these aspects, electronic textiles seem to be a highly suitable possibility, due to the unique characteristics of textiles such as being light weight and flexible and their inherent warmth and the property to conform. Therefore, e-textiles have evolved into fiber-based electronic apparel or body attachable types in order to foster significant industrialization of the key components with adaptable formats. Although the advances are noteworthy, their electrical performance and device features are still unsatisfactory for consumer level e-textile systems. To solve these issues, innovative structural and material designs, and novel processing technologies have been introduced into e-textile systems. Recently reported and significantly developed functional materials and devices are summarized, including their enhanced optoelectrical and mechanical properties. Furthermore, the remaining challenges are discussed, and effective strategies to facilitate the full realization of e-textile systems are suggested.

“…Among emerging nonvolatile memory devices, resistive random access memory (RRAM) has attracted significant amounts of attention because it provides a variety of advantages, including flexibility, cost‐efficiency, and simple integration with high packing density levels . In this regard, various types of RRAM, based on organic/inorganic materials, have been reported for flexible memory in the form of copper wire network‐based memory, flexible memory arrays on plastic substrates, logic‐in‐memory on fabric substrates, memory on fabric with native aluminum oxide (Al 2 O 3 ), and graphene‐oxide‐based woven memory . However, a few certain limitations, such as complicated processes, the requirement of bulky equipment to provide the necessary high temperatures and vacuum condition, and poor reliability, continue to hinder practical applications of fabric‐based electronics …”

Fabric‐based electronic textiles (e‐textiles) have been investigated for the fabrication of high‐performance wearable electronic devices with good durability. Current e‐textile technology is limited by not only the delicate characteristics of the materials used but also by the fabric substrates, which impose constraints on the fabrication process. A polydopamine (PDA)‐intercalated fabric memory (PiFAM) with a resistive random access memory (RRAM) architecture is reported for fabric‐based wearable devices, as a step towards promising neuromorphic devices beyond the most simple. It is composed of interwoven cotton yarns. A solution‐based dip‐coating method is used to create a functional core–shell yarn. The outer shell is coated with PDA and the inner shell is coated with aluminum (Al) surrounding the core yarn, which serves as a backbone. The Al shell serves as the RRAM electrode and the PDA is a resistive‐switching layer. These functional yarns are then interwoven to create the RRAM in a lattice point. Untreated yarn is intercalated between adjacent functional yarns to avoid cell‐to‐cell interference. The PiFAM is applied to implement a synapse, and the feasibility of a neuromorphic device with pattern recognition accuracy of ≈81% and the potential for application in wearable and flexible electronic platforms is demonstrated.

challenge, however, is to engender electrical functionalities in textiles while preserving the desirable textile qualities such as softness, comfort, flexibility, and texture that arise from its hierarchical structure through the complex interaction of inherent fiber material properties and the characteristic textile structural features at multiple length scales. To this end, among all the different potential routes of incorporating electronic functionalities into textiles, integration of textile fibers performing as electrical devices, on its own or when assembled, seems to provide the most obvious, unobtrusive, and practical means. Appropriately designed flexible fiber-based electronics are fundamentally transformational; they present very attractive possibilities of ease of manufacturing using standard fiber-extrusion, roll-to-roll textile processing technologies, and enable high spatial sensing density with redundancy within the textile structure. The utility of fiber-based electronics has been recognized as a key step for truly mass-produced e-textiles. Accordingly, the constituents (e.g., fibers or yarns) of textile products have been directly fashioned into electrical devices by incorporating appropriate functional design and materials. These include "fiber"shaped photovoltaic devices, [1,2] transistors, [3][4][5] logic circuits, [6,7] sensors, [8,9] actuators, [10][11][12] other electronic/optical devices [13][14][15] in addition to "fabric"-based devices. [16,17] Modulation of resistance and/or capacitance have been the two most common strategies to sense various physical stimuli, such as applied forces [8,18] and moisture. [19,20] Piezoresistive sensors in the form of fibers/yarns and printed layers on fabrics have been proposed for monitoring motion, posture, and various physiological signals for patient monitoring and rehabilitation. [21,22] For pressure measurements, multicore fibers consisting of layers of soft dielectric and conductive polymers or thin metal films, [23,24] sets of orthogonal fibers, [25,26] or fabric-like structures with soft dielectric and conductive fibers [27] have been employed to form capacitive structures. While remarkable progress has been made in e-textiles, practical real-life products in e-textiles remain elusive. Arguably, the most difficult challenge has been the development of truly textile/fiber-compatible materials/devices and practical Soft polymer-based sensors as an integral part of textile structures have attracted considerable scientific and commercial interest recently because of their potential use in healthcare, security systems, and other areas. While electronic sensing functionalities can be incorporated into textiles at one or more of the hierarchical levels of molecules, fibers, yarns, or fabrics, arguably a more practical and inconspicuous means to introduce the desired electrical characteristics is at the fiber level, using processes that are compatible to textiles. Here, a prototype multimodal and multifunctional sensor array formed within a woven fabr...
