Abstract

This review is a critical analysis of the current state‐of‐the‐art in core spun yarn textile triboelectric nanogenerators (CSY‐T‐TENGs) for self‐powered smart sensing applications. The rapid expansion of wireless communication, flexible conductive materials, and wearable electronics over the last ten years is now demanding autonomous energy, which has created a new research space in the field of wearable T‐TENGs. Current research is exploring T‐TENGs made from CSYs as stable and reliable energy harvesters and sensing devices for modern wearable IoT platforms. CSY‐TENGs are emerging as an important technology due to its simple structure, low cost, and excellent performance in converting mechanical energy into electrical energy and due to its sensing ability. This paper provides a critical review on current progress, it analyzes the unique advantages of CSYs T‐TENGs over conventional T‐TENGs, it describes fabrication techniques and discusses the materials used along with their properties and electrical performance characteristics, and it highlights the recent advancements in their integration with self‐excitation circuits, charge storage devices and IoT‐enabled smart sensing applications, such as environmental and health monitoring. In the conclusion, it discusses the challenges and future directions of CSYs T‐TENGs and it provides a future road map for optimization, upscaling, and commercialization of the technology.

A single-electrode mode triboelectric nanogenerator based on natural leaves for harvesting energy

“…1 The triboelectric nanogenerator (TENG) based on the principles of frictional electrication and electrostatic induction can effectively convert low-frequency and chaotic mechanical energy in the environment into electrical energy, becoming a simple and attractive method of energy generation without external power generation equipment. 2 Since Wang Zhonglin began this creative research in 2012, 3,4 TENG has provided extensive applications in elds such as self-powered sensing, [5][6][7][8] clean energy harvesting, [9][10][11][12] intelligent wearable fabrics, [13][14][15] and air purication. [16][17][18] Using TENG as a power source to power electronic devices can effectively solve the problems of high cost and portability of traditional power generation methods.…”

Scalable and Ultra‐Sensitive Nanofibers Coaxial Yarn‐Woven Triboelectric Nanogenerator Textile Sensors for Real‐Time Gait Analysis

“…The performance of yarn‐woven TENG is intrinsically tied to the production technique of coaxial fibers. [ 23 ] A variety of methods, such as coaxial spinning, coating, film‐wrapping, and yarn‐wrapping have been developed for coaxial‐fiber TENGs. [ 24 , 25 , 26 ] In the coaxial spinning, the inner conductive and outer triboelectric fluids are extruded into the coagulation bath to form coaxial fibers.…”

A Review of Recent Advances in Human-Motion Energy Harvesting Nanogenerators, Self-Powering Smart Sensors and Self-Charging Electronics

“…For example, Qi et al [106] Even though compared to other textile-based TENGs their fabrication process is complicated and the energy output is one of the lowest, their advantage is their small size, which helps with integration into clothes [84]. A critical review on the core-spun yarn-based TENGs has been released recently [109]. (d) Electronic skin-wearable thin films and thin sheets or nonwoven composites.…”
