“…This increase in output voltage with gas pressure may be attributed to the less energy consumption due to the lower breakdown voltage and effortless formation of the conducting path. As the pressure decreases, the number of gas molecules decreases and the gas molecule spacing increases in the airtight condition, which results in a larger mean free path and a longer acceleration time for electrons and ions . The larger acceleration time allows electrons and ions to reach higher kinetic energy.…”

“…Such differences in output voltage may be attributed to the less energy consumption due to the lower breakdown voltage and different electron affinity. According to Table S4, Supporting Information, one can see that the molecular weight of N 2 is less than that of air and CO 2 , which N 2 provides the largest mean free path for electrons . Although He has the lowest molecular weight compared with N 2 , air, and CO 2 , He has higher electron affinity, causing stronger electron adsorption, and a smaller mean free path of electrons and ions .…”

Triboelectric nanogenerators (TENGs) are effective for harvesting mechanical energy and converting into electricity. Such devices have high output voltage and low current, appearing as high output impedance. Impedance mismatches involving these devices create challenges in power usage, storage, and management. Herein, a dual‐tip‐assisted TENG is developed and its electrical output performance under airtight condition is investigated. The generated charges can rapidly accumulate at the dual tip and produce a high potential difference. Such a potential difference accelerates the induced charges’ transfer speed and quantity. Gas discharge occurs once the potential exceeds some threshold, providing a conduction path for accumulated charges. With the help of such dual‐tip peak power multiplier, TENG's peak‐to‐peak short‐circuit current and open‐circuit voltage are 433% and 145% higher, respectively. The peak power reaches a maximum of 34.8 mW with a 100 kΩ load resistance, whereas that of the original TENG is 1.5 mW with a 100 MΩ load resistance, indicating 22.2 times of peak power increase and an optimal matching impedance decrease by three orders of magnitude. The results indicate that this multiplier is meaningful for the optimization of TENG's output and impedance.

The flourishing development of multifunctional flexible electronics cannot leave the beneficial role of nature, which provides continuous inspiration in their material, structural, and functional designs. During the evolution of flexible electronics, some originated from nature, some were even beyond nature, and others were implantable or biodegradable eventually to nature. Therefore, the relationship between flexible electronics and nature is undoubtedly vital since harmony between nature and technology evolution would promote the sustainable development. Herein, materials selection and functionality design for flexible electronics that are mostly inspired from nature are first introduced with certain functionality even beyond nature. Then, frontier advances on flexible electronics including the main individual components (i.e., energy (the power source) and the sensor (the electric load)) are presented from nature, beyond nature, and to nature with the aim of enlightening the harmonious relationship between the modern electronics technology and nature. Finally, critical issues in next-generation flexible electronics are discussed to provide possible solutions and new insights in prospective exploration directions.

Electrostatic Discharge - From Electrical Breakdown in Micro-Gaps to Nano-Generators

View full text Add to dashboard Cite

Electrical discharge is generally considered as a negative effect in the electronic industry and often causes electrostatic discharge (ESD) and thus failure of electronic components and integrated circuits (IC). However, this effect was recently used to develop a new energy-harvesting technology, direct-current triboelectric nanogenerator (DC-TENG). In this chapter, its fundamental mechanism and the working modes of the nanogenerator will be presented. They are different from the general alternating current TENG (AC-TENG) invented in 2012, which is based on triboelectrification and electrostatic induction. Taking advantage of the electrostatic discharge, it can not only promote the miniaturization trend of TENG and self-powered systems, but also provide a paradigm shifting technique to in situ gain electrical energy.
