single step Fluorocarbon plasma treatment induced wrinkle structure for high performance triboelectric nanogenerator
Small, 2016Co-Authors: Xiaoliang Cheng, Bo Meng, Xuexian Chen, Haotian Chen, Zongming Su, Haixia ZhangAbstract:A triboelectric nanogenerator (TENG) has been thought to be a promising method to harvest energy from environment. To date, the utilization of surface structure and material modification has been considered the most effective way to increase its performance. In this work, a wrinkle structure based high-performance TENG is presented. Using the Fluorocarbon plasma treatment method, material modification and surface structure are introduced in one step. The output ability of TENG is dramatically enhanced. After the optimization of plasma treatment, the maximum current and surface charge density are 182 μA about 165 μC m−2. Compared with untreated TENG, the wrinkle structure makes the current and surface charge density increase by 810% and 528%, separately. X-ray photoelectron spectroscopy is employed to analyze the chemical modification mechanism of this Fluorocarbon plasma treatment. Facilitated by its high output performance, this device could directly light 76 blue light emitting diodes under finger typing. The output electric energy could be stored then utilized to power a commercial calculator. As a result of the simple fabrication process and high output ability, devices fabricated using this method could bring forward practical applications using TENGs as power sources.

high performance triboelectric nanogenerator with enhanced energy density based on single step Fluorocarbon plasma treatment
Nano Energy, 2014Co-Authors: Xiaosheng Zhang, Renxin Wang, Bo Meng, Wei Hu, Wei Wang, Zhihong Li, Haixia ZhangAbstract:Abstract Recently triboelectric nanogenerator (TENG) devices that transform environmental mechanical energy to electric power have been demonstrated as a renewable, clean and usable power source. However, the TENG output power still should be enhanced to better meet practical needs, and the working ability for practical applications should be further investigated. Here, we demonstrate a novel high-performance TENG by using a single-step Fluorocarbon plasma treatment, which can significantly strengthen the TENG output performance. After the optimization of plasma treatment, the maximum instantaneous energy area density of the TENG with micro/nano hierarchical structures is enhanced by 278% to 4.85 mW/cm2, with a peak output voltage of 265 V and current density of 18.3 μA/cm2. The reliability and stability of this single-step Fluorocarbon plasma enhancement process were widely and deeply investigated by systematically comparative experiments. The density functional theory (DFT) is employed to analyze the chemical modification mechanism of this Fluorocarbon plasma treatment, modeling for the first time the energy required for electron transfer for different friction materials at molecular level based on first-principle calculations. The ability of this TENG to work in the practical environmental, especially in the biomedical field, has been demonstrated by the investigation of the effect of the key environmental factor (i.e., humidity) on the TENG output performance, and a quantitative relation has been figured out. Based on this relation, humidity is established as a new consideration for future studies of TENG performance, and a novel self-powered humidity monitoring sensor is proposed. This high-output TENG is also successfully applied to drive an implantable microneedle electrode array to stimulate a frog's sciatic nerve. This represents the first application of a TENG for sustainably powering a biomedical microsystem implanted in real biological tissue, moving closer to practical biomedical applications of TENGs.
