Triboelectric Nanogenerators: Enhancing the Output Performance of Triboelectric Nanogenerator via Grating‐Electrode‐Enabled Surface Plasmon Excitation (Adv. Energy Mater. 44/2019)

Abstract

In article number 1902725, Xiaojing Mu, Zhong Lin Wang, Ya Yang and co‐workers report a new mechanism to enhance the output performance of triboelectric nanogenerators. The hot electron‐hole pairs decaying from the surface plasmon resonance effectively enhance the output of TENGs while reducing their output impedances. A 4.5‐fold enhancement in output power and a 75% reduction in output impedance are acquired.

Giant tridimensional power responses in a T-shaped magneto–mechano–electric energy harvester

“…To reduce the usage of chemical batteries classified as ''hazardous wastes'' for environmental protection, 2,3 energyharvesting technology is a highly promising candidate to supply energy to the current finite-life chemical batteries to power those thousands of low-energy-consumption devices in WSNs. 4 Waste energy sources, such as vibration, [5][6][7] waves, 8 heat, 9 light, 10 and stray magnetic field, [11][12][13][14][15][16][17] are widespread in modern society and can be freely harvested. Especially, a considerable energy from stray magnetic fields exists widely around power transmission networks around modern infrastructures in the urban environment.…”

Biowaste Eggshell Membranes for Bio-triboelectric Nanogenerators and Smart Sensors

“…A popular candidate for a portable energy source that harvests energy from the environment is the triboelectric nanogenerator (TENG), first introduced by Wang et al TENGs have many attractive features, including low fabrication costs, lightweight, high energy efficiency, and a wide range of materials and structures to choose from when designing a device, − leading to a large variety of viable device setups. − Among other factors, the contact area between the triboelectric layers plays a major role in determining the properties of a TENG. − Previous studies have focused on investigating the effects of material selection, − surface modification, − and surface morphology, − on the mechanism of operation and performance of TENGs. Because increasing the dielectric constant can enhance the capacitance of the dielectric layer, thereby increasing the surface charge density, the dielectric constant of a triboelectric material is an important factor affecting triboelectric performance …”
