Smart Wearable kevlar based safeguarding electronic textile with excellent sensing performance
Soft Matter, 2017Co-Authors: Sheng Wang, Mei Liu, Shuaishuai Zhang, Linfeng Bai, Min Sang, Shouhu Xuan, Wanquan Jiang, Xinglong GongAbstract:A novel S-ST/MWCNT/Kevlar-based Wearable electronic textile (WET) with enhanced safeguarding performance and force sensing ability was fabricated. Stab resistance performance tests under quasi-static and dynamic conditions show that the maximum resistance force and penetration impact energy for the WET are 18 N and 11.76 J, which represent a 90% and 50% increment with respect to the neat Kevlar, respectively. Dynamic impact resistance tests show that the WET absorbs all the impact energy. The maximum resistance force of the WET is 1052 N, which represents an improvement of about 190% with respect to neat Kevlar. With the incorporation of multi-walled carbon nanotubes (MWCNTs), the WET can achieve a stable electrical conductivity of ∼10-2 S m-1, and the conductivity is highly sensitive to external mechanic forces. Notably, the sensing fabric also exhibits an outstanding ability to detect and analyze external forces. In addition, it can be fixed at any position of the human body and exhibits an ideal monitoring performance. Because of its flexibility, high sensitivity to various types of deformations and excellent safeguarding performance, the WET has a strong potential for Wearable monitoring devices that simultaneously provide body protection and monitor the movements of the human body under various conditions.

Smart Wearable sensors based on triboelectric nanogenerator for personal healthcare monitoring
Micromachines, 2021Co-Authors: Xuelian Wei, Junhuan Chen, Zhong Lin WangAbstract:Accurate monitoring of motion and sleep states is critical for human health assessment, especially for a healthy life, early diagnosis of diseases, and medical care. In this work, a Smart Wearable sensor (SWS) based on a dual-channel triboelectric nanogenerator was presented for a real-time health monitoring system. The SWS can be worn on wrists, ankles, shoes, or other parts of the body and cloth, converting mechanical triggers into electrical output. By analyzing these signals, the SWS can precisely and constantly monitor and distinguish various motion states, including stepping, walking, running, and jumping. Based on the SWS, a fall-down alarm system and a sleep quality assessment system were constructed to provide personal healthcare monitoring and alert family members or doctors via communication devices. It is important for the healthy growth of the young and special patient groups, as well as for the health monitoring and medical care of the elderly and recovered patients. This work aimed to broaden the paths for remote biological movement status analysis and provide diversified perspectives for true-time and long-term health monitoring, simultaneously.

self powered versatile shoes based on hybrid nanogenerators
Nano Research, 2018Co-Authors: Long Liu, Wei Tang, Chaoran Deng, Baodong Chen, Kai Han, Wei Zhong, Zhong Lin WangAbstract:A triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG) were hybridized to harvest the human mechanical energy. By an effective conjunction of triboelectrification and electromagnetic induction, the hybridized nanogenerator with a radius of 2 cm and height of 1.2 cm could charge a 1,000 μF capacitor to 5.09 V after 100 cycles of vibration. This mini-sized hybrid nanogenerator could then be embedded in shoes to serve as an energy cell. Typical outdoor applications—including driving with a Global Positioning System (GPS) device, charging a Li-ion battery and a cell phone—were successfully demonstrated, suggesting its potential application in Smart Wearable electronics and future suits of soldiers.

energy efficient fully flexible high performance tactile sensor based on piezotronic effect piezoelectric signal amplified with organic field effect transistors
Nano Energy, 2020Co-Authors: Jian Wang, Jianfeng Jiang, Congcong Zhang, Mingyuan Sun, Shuwei Han, Ruitong Zhang, Na Liang, Dehui Sun, Hong LiuAbstract:Abstract Fully flexible piezoelectric tactile sensors with low power consumption and high sensitivity play an important role in artificial intelligence, advanced manufacturing, and Smart Wearable devices. Herein, we constructed a high-performance, energy-efficient, and fully flexible piezoelectric tactile sensor based on piezotronic effect through the integration of piezoelectric materials with the mechanical-to-electrical conversion function of β polyvinylidene fluoride (PVDF) nanorod arrays and the signal amplification function of organic field-effect transistor (OFET) devices. PVDF nanorod arrays, which considerably improve the piezoelectric properties of materials, transform the external mechanical force into piezoelectric voltage to drive the OFET. Further, the piezoelectric voltage can be effectively amplified using an OFET to improve the sensitivity of the tactile sensor. Enabled by the unique structure of sensing devices and well-defined active materials, the fabricated tactile sensor exhibited excellent pressure sensitivity, detection limit, and response time of 5.17 kPa⁻1, 175 Pa, and 150 ms, respectively. In addition, using a sophisticated fabrication process, we demonstrated a flexible integrated tactile sensor array with a 3 × 3 cell on a polyethylene terephthalate (PET) substrate to detect the bending angle of the user's wrist on which the fabricated device was mounted. This study uses piezotronic transistors to convert pressure into electrical signals without applying a gate voltage, which can substantially simplify circuit models and sensor distribution; additionally, the fabricated device provides technical support for flexible electronic skin (e-skin).

a highly stretchable transparent self powered triboelectric tactile sensor with metallized nanofibers for Wearable electronics
Advanced Materials, 2018Co-Authors: Xiandi Wang, Yufei Zhang, Xiaojia Zhang, Zhihao Huo, Miaoling Que, Zhengchun Peng, Hui Wang, Caofeng PanAbstract:Recently, the quest for new highly stretchable transparent tactile sensors with large-scale integration and rapid response time continues to be a great impetus to research efforts to expand the promising applications in human-machine interactions, artificial electronic skins, and Smart Wearable equipment. Here, a self-powered, highly stretchable, and transparent triboelectric tactile sensor with patterned Ag-nanofiber electrodes for detecting and spatially mapping trajectory profiles is reported. The Ag-nanofiber electrodes demonstrate high transparency (>70%), low sheet resistance (1.68-11.1 Ω □-1 ), excellent stretchability, and stability (>100% strain). Based on the electrode patterning and device design, an 8 × 8 triboelectric sensor matrix is fabricated, which works well under high strain owing to the effect of the electrostatic induction. Using cross-locating technology, the device can execute more rapid tactile mapping, with a response time of 70 ms. In addition, the object being detected can be made from any commonly used materials or can even be human hands, indicating that this device has widespread potential in tactile sensing and touchpad technology applications.
