fiber fabric based piezoelectric and triboelectric nanogenerators for flexible stretchable and Wearable Electronics and artificial intelligence
Advanced Materials, 2020Co-Authors: Kai Dong, Zhong Lin Wang, Xiao PengAbstract:Integration of advanced nanogenerator technology with conventional textile processes fosters the emergence of textile-based nanogenerators (NGs), which will inevitably promote the rapid development and widespread applications of next-generation Wearable Electronics and multifaceted artificial intelligence systems. NGs endow smart textiles with mechanical energy harvesting and multifunctional self-powered sensing capabilities, while textiles provide a versatile flexible design carrier and extensive Wearable application platform for their development. However, due to the lack of an effective interactive platform and communication channel between researchers specializing in NGs and those good at textiles, it is rather difficult to achieve fiber/fabric-based NGs with both excellent electrical output properties and outstanding textile-related performances. To this end, a critical review is presented on the current state of the arts of Wearable fiber/fabric-based piezoelectric nanogenerators and triboelectric nanogenerators with respect to basic classifications, material selections, fabrication techniques, structural designs, and working principles, as well as potential applications. Furthermore, the potential difficulties and tough challenges that can impede their large-scale commercial applications are summarized and discussed. It is hoped that this review will not only deepen the ties between smart textiles and Wearable NGs, but also push forward further research and applications of future Wearable fiber/fabric-based NGs.

Nano Energy, 2019Co-Authors: Weixing Song, Maoqing Zhang, Xinyuan Li, Chunlei Zhang, Ping Cheng, Zhong Lin Wang, Jie WangAbstract:Abstract Developing lightweight, flexible and sustainable power sources is desirable and favorable for Wearable Electronics with the rapid advancement of portable devices. Here, a highly elastic and sustainable power source is fabricated for harvesting and storing energy simultaneously from ambient sunshine and human movement. Flexible fiber-shaped dye-sensitized solar cells are smartly integrated with triboelectric nanogenerators and serve as generating set. The supercapacitors as energy storage devices can store direct current energy for the solar cells and alternating current energy from the triboelectric nanogenerators after rectified at the same time. Furthermore, the supercapacitors are easily integrated with generating set due to the same electrode materials with triboelectric nanogenerators. Due to the all flexible devices, the size of the whole power system can be easily tuned and connected with electronic devices to create self-powered Wearable Electronics.

self powered inhomogeneous strain sensor enabled joint motion and three dimensional muscle sensing
ACS Applied Materials & Interfaces, 2019Co-Authors: Haiming Wang, Zhong Lin Wang, Wei Zhong, Tao Jiang, Ding Li, Liang XuAbstract:Wearable Electronics containing different functional sensors with abilities to meet people’s daily needs are highly desirable. Here, a stretchable triboelectric nanogenerator (TENG) for Wearable Electronics is demonstrated. By stacking two layers of silicone rubbers embedded with silver nanowires (AgNWs) and a Ni foam as electrodes, respectively, the fabricated TENG can serve as a new type of sensor that is Wearable, stretchable, skin-friendly, noninvasive, and durable. It can convert mechanical deformation into electric signals. Deformation like stretching and extruding of the TENG results in interlayer rubbing because of inhomogeneous strain, producing triboelectric charges that can induce voltage signals in the electrodes in response to the deformation. On the basis of the principle, a joint sensor based on the TENG is demonstrated, which can generate different output voltages according to the bending degrees of the joint. Furthermore, a three-dimensional sensor integrating three TENGs is fabricated to...

a high performance all solid state yarn supercapacitor based on polypyrrole coated stainless steel cotton blended yarns
Cellulose, 2019Co-Authors: Chuanjie Zhang, Zeqi Chen, Weilin Xu, Jie XuAbstract:Yarn supercapacitors (YSCs) are attracting considerable interest for Wearable Electronics and intelligent textiles due to their high flexibility and weavability. In the present study, stainless steel/cotton blended yarns were used as supports and current collectors to produce polypyrrole-coated yarn electrodes. The as-made YSC exhibited a high areal specific capacitance of 344 mF cm−2 at a current density of 0.6 mA cm−2 and good cycling stability (almost 93% capacitance retention over 1000 cycles). Moreover, the YSC could be knitted into other fabrics without damaging its original structure and electrochemical performance owing to its superior flexibility, indicating that it can meet the requirements of energy-storage devices for Wearable Electronics.

Advanced Energy Materials, 2017Co-Authors: Zhong Lin Wang, Jie Wang, Wenbo Peng, Long Lin, Sihong Wang, Gong ZhangAbstract:Wearable Electronics have attracted a wide range of attention with various functions due to the development of semiconductor industry and information technology. This work focuses on a triboelectric nanogenerator-based self-charging power system as a continuous energy source for Wearable Electronics. The triboelectric nanogenerator has a multilayer elastomeric structure with closely stacked arches as basic functional units. Owing to material and structural innovations, this triboelectric nanogenerator performs outstanding electric output with the maximum volume charge density ≈0.055 C m−3 and practical properties for energy harvesting from body motions. Utilizing the triboelectric nanogenerator as outsole to harvest energy from walking or jogging, a pair of shoes is fabricated with the maximum equivalent charge current of each shoe being around 16.2 µA and specific fitness functions realized on each shoe separately without complex connections.

Self-powered textile for Wearable Electronics by hybridizing fiber-shaped nanogenerators, solar cells, and supercapacitors
Science Advances, 2016Co-Authors: Zhen Wen, Min Hsin Yeh, Li Ping Zhu, Hengyu Guo, Jianan Deng, Xuhui Sun, Weidong Xu, Chenguo Hu, Xiao-fei Wang, Yunlong Zi, Xin Wang, Jie Wang, Lei Zhu, Zifeng WangAbstract:Wearable Electronics fabricated on lightweight and flexible substrate are believed to have great potential for portable devices, but their applications are limited by the life span of their batteries. We propose a hybridized self-charging power textile system with the aim of simultaneously collecting outdoor sunshine and random body motion energies and then storing them in an energy storage unit. Both of the harvested energies can be easily converted into electricity by using fiber-shaped dye-sensitized solar cells (for solar energy) and fiber-shaped tribo- electric nanogenerators (for random body motion energy) and then further stored as chemical energy in fiber- shaped supercapacitors. Because of the all–fiber-shaped structure of the entire system, our proposed hybridized self-charging textile system can be easily woven into electronic textiles to fabricate smart clothes to sustainably operate mobile or Wearable Electronics.
