Monodispersed polystyrene (PS) particles were prepared and deposited onto various kinds of textile fabrics using a gravity sedimentation method. The monodispersed PS particles were self-assembled on fabrics to form a photonic crystal, which has an iridescent structural color. The structural color of fabrics was determined by the bandgaps of photonic crystals. Moreover, the effect of the fabric substrate, including the raw materials, base color, and fabric weave, etc., on the structural color of the photonic crystals was studied. Scanning electron microscopy and UV-vis spectrometry were adopted to characterize the structure and optical performance of photonic crystals. The results indicate that the silk fabric with a black base color and satin weave contribute to a bright and pure textile structural color. In order to solve the problem of low color fastness of the structural color on the fabric surface, silk fibroin (SF) was introduced to the PS microsphere solution. Results show that the addition of SF slightly affects the brightness of the structural color, while it has a certain reinforcing effect on the structural color fastness to rubbing and washing.Keywords:photonic crystals;structural color;fabric substrate;silk fibroin;color fastness

The demand for wearable monitoring devices in contemporary medicine has significantly increased, especially in dynamic environments where traditional bulky equipment is impractical. Conventional flexible wearable devices or systems suffer from limited air and moisture permeability, lack of stretchability, and high power consumption, which restrict their long-term usage and comfort. Herein, a stretchable and breathable backscattered monitoring system (SBBMS) is introduced, integrated with a fabric substrate. To address the challenges associated with fabric substrate system fabrication and encapsulation, a printing-cutting-transfer technology is proposed. This method enables the creation of unique, low-cost, high-precision, and robust circuit routing and electronic devices on fabric, maintaining high compatibility with commercial surface mounting technology while minimizing sacrifices in breathability. Additionally, a backscatter communication mechanism is designed and implemented to achieve wireless data transmission, which significantly reduces power consumption. Combined with energy management technology and hydrogel batteries, the SBBMS receives safe, multi-source, and eco-friendly energy support. Furthermore, through meticulous design, all modules—including the antenna, circuit, and battery—are made stretchable, providing the system with excellent strain-resistive performance. The approach paves the way for the development of breathable, high-performance, and highly integrated fabric-based wearable systems, catering to specific user groups such as athletes, soldiers, and pilots.

Relative humidity (RH), temperature, and pH as important environmental parameters that are closely related to industry, agriculture, and people's life. Therefore, the development of a colorimetric sensor that can monitor the RH, temperature, and pH in real-time is highly desired. In this work, a fabric-based flexible colorimetric sensor is easily manufactured by screen printing the mixture of cresol red (CR), thymol blue (TB) and boric acid (H 3 BO 3 ) on the fabric. Compared with the traditional single stimulus colorimetric sensor, this fabric device can respond to multiple stimulus factors including humidity, temperature, or pH. The simple coating treatment can endow the colorimetric sensor with fast response without compromising its flexibility. Exposed to different stimulus conditions, the colorimetric sensor has a unique color change effect, such as humidity-responsive pink-yellow, temperature-responsive yellow-pink, and pH-responsive pink-purple. The flexibility and versatility of the fabric sensors are showcased with the applications in temperature/humidity/pH detection, cultural relics protection and information encryption. We believe the colorimetric sensor would have potential in environmental monitoring, health care, encrypted information patterns, and intelligent wearables, etc.

The dual-mode organic electrochemical transistors (OECT) were successfully assembled on fabric. The property of different devices has been compared. In the depletion mode, the PEDOT: PSS/textile-based OECT exhibit high transconductance of 75 mS, and the switching ratio of 8 × 10 2 . In accumulation mode, the PEDOT: PSS/DETA/textile-based OECT exhibit transconductance of 0.55 mS, switching ratio can reach 31.7. Both modes have good cycle stability. A lactate (LA) sensor was prepared by modifying the gate electrode with lactate oxidase. The sensitivity of the sensor is 69.97 mV/decade and 47.8 mV/decade in the depletion and accumulation mode, respectively. The LA sensor in both modes has good linear response in a wide concentration range of 100 pM-10 mM. The sensor has been successfully applied to the detection of LA in sweat sample. It has the advantages of simple preparation, good performance, and convenient integration into clothes, which provides a feasible platform for intelligent wearable and portable medical detection.

Highly efficient and flexible power sources have always been the focus and goal in the field of wearable electronics. However, the existing wearable power sources are limited by their large size, high weight, electrolyte leakage, and poor mechanical compliance, which seriously hinders their practical applications. Herein, we propose a novel strategy to achieve and demonstrate a fabric-based high-performance wearable triboelectric nanogenerator (TENG) structure. The metals of gallium (Ga), bismuth (Bi), indium (In), and tin (Sn) are mixed according to specific mass ratios, and then they are transformed in liquid phase to form room-temperature multiphase soft metals of GaBiInSn. The material exhibits both metallic and fluidic properties, and possesses a characteristic of multiphase structure. The GaBiInSn material is directly deposited between polytetrafluoroethylene (PTFE) layers and nonwoven fabrics to establish multi-level conductive and frictional interfaces, creating charge transfer and solid-liquid hybrid dielectric layers. Therefore, the thin film-type triboelectric nanogenerators with a structure of PTFE/GaBiInSn/nonwoven fabric (LM-P-TENGs) is manufactured. The LM-P-TENGs can be integrated onto fabrics without compromising their breathability, comfortableness, and flexibility. Particularly, LM-P-TENGs efficiently convert the mechanical energy of human limb movements into sustainable electrical energy output. Under the human limb mechanical triggering conditions, LM-P-TENG achieves a champion specific open-circuit voltage up to 900 V, peak short-circuit current density of 43.3 mA/m 2 , and high power density of 12.56 W/m 2 . This work demonstrates the application potential of room-temperature multiphase soft materials in flexible wearable power sources, while introducing a novel power supply mode for wearable electronics. Additionally, the LM-P-TENGs also present applications in self-powered wearables, medical biosensing systems, human-machine interaction systems, near-eye display systems, etc. for the flexible electronics.

Wearable technology is experiencing remarkable progress, prompting the need for sustainable power sources like triboelectric nanogenerators (TENGs). However, integrating TENGs into fabrics and insufficient power outputs that allows for comfortable wear without obstructing user's movements presents a significant challenge. In this study, a novel kind of diamond-structured fabric-based triboelectric nanogenerators (DSF-TENGs) is introduced utilizing an easy, economical, and scalable weaving method without any chemical modification. Owing to its 3D diamond pattern, surface interactions are enhanced for greater charge generation together with strengthened mechanical engagement for more effective charge transfer. The DSF-TENG, with its unique self-resilient structure, achieves impressive electric performance, including output voltage of ≈763 V, short-circuit current of ≈20.4 µA, and power density of 2862.78 mW m −2 , which is multiple times higher than most existing fabric-based TENGs. It also offers excellent air permeability of 560 mm s −1 , consistent electricity generation and sensing even after ten washing cycles, and incredible durability, withstanding over 30 000 cycles. Furthermore, DSF-TENG is included in an insole that is capable of sensing gait patterns, walking speed, and fall detections of patients with Parkinson's disease. The remarkable power generation capabilities of DSF-TENG indicate a strong potential for future developments in wearable electronics and healthcare applications.

The shortage of fossil fuels and freshwater resources has become a serious global issue. Using solar energy to extract clean water with a photothermal conversion technology is a green and sustainable desalination method. Integrated electricity generation during the desalination process maximizes energy utilization efficiency. Herein, a solar-driven steam and electricity generation (SSEG) system based on an all-in-one evaporator is prepared via a scalable technology. Carbon black is selected as the absorber for solar energy harvesting as well as the functional substance for simultaneous electricity generation. Fabric substrate with flexible structure, porous channel, and capillary effect is vital for directional brine supply, multiple solar absorption, and thermal management. The high evaporation rate (1.87 kg m −2 h −1 ) and voltage output (324 mV) can be achieved with an all-in-one device. The stable electricity output can be maintained over 40000 s. The SSEG performance remains constant after 15 operation cycles or 20 wash cycles. The integrated device balances excellent effectiveness and practicality, providing a viable path for clean desalination and electricity generation.
