Abstract: Exploring different types of materials in triboelectric nanogenerator (TENG) research remains a dynamic and evolving field. This work marks an important milestone in this journey by introducing phosphor material, particularly zinc vanadate (Zn 3 V 2 O 8 , ZVO), into TENG technology for the first time. TENG uses ZVO and silicone films as active triboelectric layers. The fabricated TENG exhibits remarkable performance, producing an output voltage of 515 V and a current of 178 μA, resulting in an impressive power… Show more

Smart textiles represent a revolutionary approach to wearable technology with applications ranging from healthcare to energy harvesting. This review paper explores the importance of textile technologies and highlights their potential to revolutionize consumer electronics. Conventional technologies are sometimes heavy, and lack comfort and flexibility, but smart textiles seamlessly integrate into everyday clothing, improving wearability and user experience. The article emphasizes the need for sustainable sourcing and environmentally friendly production methods, as well as responsible manufacturing and disposal practices. Manufacturing techniques such as wet spinning, melt spinning, electrostatic spinning, weaving, knitting, and printing are detailed and shed light on their role in incorporating electronics into textiles. Several applications of textile‐based devices are being explored, including biochemical sensing, temperature monitoring, energy harvesting, energy storage, and smart displays. Each application demonstrates the versatility and potential of smart textiles in different areas. Despite optimistic progress, challenges remain, from improving energy efficiency to protecting user privacy and data security. The review analyzes these problems and suggests future improvements, including interdisciplinary collaboration to find new solutions. Finally, an overview of the current state of smart textiles provides the future of this technology. It serves as an in‐depth reference for academics and readers interested in understanding recent advances and discoveries in textile technologies, highlighting the importance of this rapidly growing industry.

The demand for sustainable energy resources to power sensor networks such as consumer electronics, agricultural technologies, digital forest management, and home automation is rapidly increasing. There are sustainability challenges to consider, where waste waterproof textiles are critical to encourage the development of a circular economy in the development of new energy technologies. This present work focuses on the utilization of direct waste waterproof textiles to design two types of triboelectric nanogenerator (TENG), which include a liquid‐solid based TENG (L‐S TENG) and a flapper‐type TENG. The bottom electrode configuration for the L‐S TENG and single electric mode working mechanism is considered for the flapper‐type TENG. Waste waterproof textiles can lead to a possible expansion of sustainable material for energy harvesters. The raincoat textile‐based L‐S TENG (L‐STENG‐R) is able to generate 0.5 V at a tilt angle of 50 degrees and power of 0.41 nW. TENGs based on discarded waterproof textiles are further utilized to demonstrate their phase change sensing, along with wind and water energy harvesting. This approach focus on decreasing waste and lower dependency on traditional resources to support environmentally responsible energy alternatives.

In recent years, multifunctional applications of the same material have gained wide recognition in various fields. The present study reports the synthesis, characterization, and multifunctional applications of europium (Eu)‐doped yttrium oxide (Y2O3) nanophosphor. Synergistic optimization of Eu‐doped Y2O3 results in enhanced photoluminescence (PL) and triboelectric nanogenerator (TENG) performance. Eu‐doped Y2O3 nanophosphors are synthesized using an autocombustion method, and comprehensive characterizations are conducted. The investigations indicate that the Eu doping significantly influences the PL intensity, with the highest emission observed at 3 mol% for powders. The synthesized nanophosphors are blended with silicone to fabricate hybrid films, which are utilized for energy harvesting applications using TENG technology. The TENG devices fabricated with these hybrid films demonstrate a notable relationship between the Eu concentration and the electrical output, achieving peak performance at 1 mol% Eu doping. The maximum output voltage of ≈535 V, short‐circuit current of ≈38 μA, and power density of 800 mW m−2 are observed. Further, TENG is demonstrated in a self‐powered UV photodetector application. The present results contribute to the improvement of sustainable energy technologies and open up a new window for multifunctional materials.
