Eco-friendly pectin polymer film-based triboelectric nanogenerator for energy scavenging

Abstract

Inspired by a desire to solve the energy-related issues in remote sensing applications, internet of things, wireless autonomous devices, and self-powered portable electronic devices, triboelectric nanogenerators (TENGs) have been highly...

A new triboelectric nanogenerator based on a multi-material stacking structure achieves efficient power conversion from discrete mechanical movement

“…25 Meanwhile, extrusion occurs between PTFE and FKM, and FKM easily turns positivecharged by transmitting electrons to PTFE. 13,24,26 Besides, PU undergoes compression deformation during extrusion, and a small amount of positive charge is also induced. 24,27 Therefore, conductive copper, FKM, and PU on Plate B are positively charged, and PTFE is electronegative.…”

“…[6][7][8][9][10] Nowadays, TENGs are thought to be a new kind of lightweight energy source that can hopefully provide reliable power support for the expansion of the Internet of Things (IoT). [11][12][13] For reacting to ambient mechanical motion in the most convenient and active manner, vertical contact separation (CS-TENG) is a ubiquitous working mode used in existing high-performance TENG designs. Benefiting from the discrepancy in electron-capturing ability between the different triboelectric layers, these TENGs achieve greater charge transfer efficiency and output voltage.…”

Stearic Acid-Enhanced Triboelectric Nanogenerators with High Waterproof, Output Performance, and Wear Resistance for Efficient Harvesting of Mechanical Energy and Self-Powered Sensing for Human Motion Monitoring

“…When external mechanical forces are periodically applied and removed on the TENG, a continuous AC output signal can be generated. The open-circuit voltage ( V OC ) and short circuit current ( I SC ) generated by SA-TENG during the contact separation process can be calculated by eqs and , respectively V normalO normalC = Q S C C = σ x ( t ) ε 0 I normalS normalC = normald Q normalS normalC normald t = S d 0 .25em normald x false( d 0 + x ( t ) false) 2 normald t = S d 0 σ υ ( t ) false( d 0 + x ( t ) false) where ε 0 , S , d , d 0 , and σ are the dielectric constant of air, the contact area, the thickness of the triboelectric layer, and the thickness and the surface charge density, respectively. υ( t ) and x ( t ) represent the velocity of the movable triboelectric layer and the separation distance between the triboelectric layers, respectively.…”

Nature‐Driven Edible Black Soldier Fly (BSF) Insect Larvae Derived Chitin Biofilm for Sustainable Multifunctional Energy Harvesting

“…[31] Since then, PENG has become a research hotspot due to its superior capacity to convert small and erratic mechanical energy, such as vibration, water flow, and human motions, into electricity. [30,32,33,34,35] In recent years, the TENG has been reported with inorganic materials like metal oxides, MOF, COF, and 2D layered materials. [36,37,38,39] Mostly, ceramic materials, such as PbTiO 3 [40] , BaTiO 3 [41] , BCST, [42] PZT, [43] and KNN, [44] are reliable piezoelectric materials.…”
