“…Both electrodes were electrically connected by resistor representing load resistance. AC voltage was measured on the load resistance and corresponding DC value was established by root mean square (RMS), as is done by many authors [37][38][39][40]. Output RMS voltage of the triboelectric generator was measured for different values of load.…”

Polyvinylidene fluoride (PVDF) is a modern polymer material used in a wide variety of ways. Thanks to its excellent resistance to chemical or thermal degradation and low reactivity, it finds use in biology, chemistry, and electronics as well. By enriching the polymer with an easily accessible and cheap variant of graphite, it is possible to affect the ratio of crystalline phases. A correlation between the ratios of crystalline phases and different properties, like dielectric constant as well as piezo- and triboelectric properties, has been found, but the relationship between them is highly complex. These changes have been observed by a number of methods from structural, chemical and electrical points of view. Results of these methods have been documented to create a basis for further research and experimentation on the usability of this combined material in more complex structures and devices.

“…Triboelectric nanogenerator (TENG) has become a research hotspot after it was proposed by Wang [ 12 ] in 2012 because of its merits of wide material selection, simple production, and flexible and wearable characteristics [ 13 , 14 ]. Based on the coupling effect of triboelectrification and electrostatic induction, the TENG harvests ubiquitous mechanical energy in the natural environment, such as wind energy [ 15 , 16 , 17 ], water energy [ 18 , 19 , 20 ], and human body movements [ 21 , 22 , 23 ]. Based on the advantages of the above-mentioned TENG, scientists have discovered that textile-based TENG (T-TENG), which combines traditional textile technology with it, is a significant and promising field of the future development of wearable electronic products, due to the advantages of air permeability, flexibility, and flexible structure.…”

In recent years, wearable electronic devices have made considerable progress thanks to the rapid development of the Internet of Things. However, even though some of them have preliminarily achieved miniaturization and wearability, the drawbacks of frequent charging and physical rigidity of conventional lithium batteries, which are currently the most commonly used power source of wearable electronic devices, have become technical bottlenecks that need to be broken through urgently. In order to address the above challenges, the technology based on triboelectric effect, i.e., triboelectric nanogenerator (TENG), is proposed to harvest energy from ambient environment and considered as one of the most promising methods to integrate with functional electronic devices to form wearable self-powered microsystems. Benefited from excellent flexibility, high output performance, no materials limitation, and a quantitative relationship between environmental stimulation inputs and corresponding electrical outputs, TENGs present great advantages in wearable energy harvesting, active sensing, and driving actuators. Furthermore, combined with the superiorities of TENGs and fabrics, textile-based TENGs (T-TENGs) possess remarkable breathability and better non-planar surface adaptability, which are more conducive to the integrated wearable electronic devices and attract considerable attention. Herein, for the purpose of advancing the development of wearable electronic devices, this article reviews the recent development in materials for the construction of T-TENGs and methods for the enhancement of electrical output performance. More importantly, this article mainly focuses on the recent representative work, in which T-TENGs-based active sensors, T-TENGs-based self-driven actuators, and T-TENGs-based self-powered microsystems are studied. In addition, this paper summarizes the critical challenges and future opportunities of T-TENG-based wearable integrated microsystems.

“…Regarding wind energy harvesting, there are mainly two categories of TENGs, which are rotational structures [ 23 , 24 , 25 , 26 , 27 , 28 ] and flutter-driven structures [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Among them, flutter-driven TENG (FTENG) usually adopts a simple structure and is easy to be designed with electronic systems.…”

We present an optimized flutter-driven triboelectric nanogenerator (TENG) for wind energy harvesting. The vibration and power generation characteristics of this TENG are investigated in detail, and a low cut-in wind speed of 3.4 m/s is achieved. It is found that the air speed, the thickness and length of the membrane, and the distance between the electrode plates mainly determine the PTFE membrane’s vibration behavior and the performance of TENG. With the optimized value of the thickness and length of the membrane and the distance of the electrode plates, the peak open-circuit voltage and output power of TENG reach 297 V and 0.46 mW at a wind speed of 10 m/s. The energy generated by TENG can directly light up dozens of LEDs and keep a digital watch running continuously by charging a capacitor of 100 μF at a wind speed of 8 m/s.
