Special Issue Information

Dear Colleagues,

We invite you to submit to a Special Issue of Energies on "Advanced Triboelectric and Piezoelectric Nanogenerators". As there is an emerging need for energy sources in various application areas, different types of energy harvesting platforms have been studied, including thermally, electromagnetically, chemically, and mechanically driven platforms. This Special Issue will be focused on the use of nanogenerators (NGs) to convert mechanical energy sources into electricity based on the development of advanced piezoelectric and triboelectric effects.

NGs have drawn a significant amount of attention due to their potential applications and ubiquitous versatility and biocompatibility. Indeed, as nanoelectronics and bioelectronics continue to be realized, complex device network systems will soon become a cornerstone of human life. Each of these will require an energy source; however, self-powered systems will be the ideal form of such device networks. From this point of view, NGs are a promising type of energy harvesting unit for these systems due to their simple structure, range of material selection options, biocompatibility, facile fabrication, use of universal mechanical energy sources, etc. In addition, self-powered bioelectronics are a fast-growing research field along with the health industry. The merits of NGs make them powerful candidate energy harvesting units and self-powered sensors for bioelectronics applications.

We welcome original research articles, reviews, and case and analytical studies that are relevant to advanced piezoelectric and triboelectric NGs and their application to nano-systems.

Abstract
This paper introduces a fiber generator using PVDF with a high-performance lead-free piezoelectric ceramic as filler. The piezoelectric ceramic filler was Ba0.84Ca0.16Ti0.90Zr0.10O3 + CuO 0.25 wt% (BCTZC0.25) sintered at 1550 °C. The BCTZC0.25 has [...] Read more.
This paper introduces a fiber generator using PVDF with a high-performance lead-free piezoelectric ceramic as filler. The piezoelectric ceramic filler was Ba0.84Ca0.16Ti0.90Zr0.10O3 + CuO 0.25 wt% (BCTZC0.25) sintered at 1550 °C. The BCTZC0.25 has an improved high-energy conversion constant (d33 × g33). The fiber generator made of PVDF/BCTZC0.25 composite fiber showed 1.6 times better piezoelectric power generation performance compared to a pure PVDF fiber generator. The PVDF/BCTZC0.25 fiber generator produced an output voltage of 1.9 V at 4 Hz. Hence, we successfully demonstrated that a composite fiber generator that uses piezoelectric ceramics which are harmless to the human body can outperform a pure PVDF fiber generator. Full article

Recently, as the demand for sustainable and renewable energy to power a large number of small electronics and sensors has increased, various mechanical energy harvesters such as electromagnetic, piezoelectric, and triboelectric generators have been highlighted because they have no environmental constraints to generate electricity and function as sustainable power sources. Among these generators, triboelectric nanogenerators (TENGs), which produce electrical energy via triboelectrification and electrostatic induction, are a promising energy harvesting technology that can utilize existing materials or the structure of existing commercial products. Considering the vast number of independent portable electronics used today, the development of hand-driven TENGs is important. There is great demand for TENG considering both commercial product-inspired designs, which are the merit of TENG itself, and the hand-driven type. However, relevant studies are still lacking, and therefore further studies in these areas are required. In this study, we developed a novel triboelectric nanogenerator (Y-TENG) inspired by the Yo-Yo that can produce a sustainable electric output by hand motion input. One generator of Y-TENG produced a maximum VOC of 10 V and an ICC of 0.7 μA. Peak/root mean square (RMS) voltage output-based quantitative analysis for the optimized number of blades and dielectric material was performed. The proposed Y-TENG was able to continuously light up three light-emitting diodes (LEDs) while the Y-TENG moved up and down. Full article

While sliding-mode triboelectric nanogenerators (S-TENGs) have been considered as one of the most promising devices for rotational energy harvesting, their inherently poor durability has been a serious bottleneck for applications. Herein, we report a three-dimensional kirigami TENG as a highly efficient and durable rotational energy harvesting device. The kirigami TENG consisted of cube-shaped paper, aluminum (Al) foil electrode and polytetrafluoroethylene (PTFE) polymer film, and converted rotational motion into multiple folding-unfolding vibrations. The rotation-folding (R-F) kirigami TENG generated an open-circuit voltage of 31 V, a short-circuit current of 0.67 μA and an instantaneous power (power density) of 1.2 μW (0.13 μW/cm2) at 200 rpm, which was sufficient to turn on 25 light-emitting diodes and a thermo-hygrometer. The triboelectric outputs of the R-F kirigami TENG were only slightly decreased even after 288,000 continuous rotations, i.e., the output remained at 86% of its initial value. This work demonstrates that an R-F kirigami TENG could be a plausible candidate to efficiently harvest various forms of rotational energy with a long-term durability. Full article
