Reliable Piezoelectricity in Bilayer WSe₂ for Piezoelectric Nanogenerators

Advanced Materials, 2017
Recently, piezoelectricity has been observed in 2D atomically thin materials, such as hexagonal‐boron nitride, graphene, and transition metal dichalcogenides (TMDs). Specifically, exfoliated monolayer MoS2 exhibits a high piezoelectricity that is comparable to that of traditional piezoelectric materials.

Nanowires for Piezoelectric Nanogenerators

2014
The nanogenerator (NG), first proposed for the purpose of self-powered nanotechnology in 2006, converts random mechanical energy into electric energy using piezoelectric zinc oxide nanowire (NW) arrays. The mechanism of the NG relies on the piezoelectric potential created in the NWs by an external strain: a dynamic straining of the NWs results in a ...

Piezoelectricity in Multilayer Black Phosphorus for Piezotronics and Nanogenerators

Advanced Materials, 2020
AbstractRecently, piezoelectric characteristics have been a research focus for 2D materials because of their broad potential applications. Black phosphorus (BP) is a monoelemental 2D material predicted to be piezoelectric because of its highly directional properties and non‐centrosymmetric lattice structure. However, piezoelectricity is hardly reported

Measurement techniques for piezoelectric nanogenerators

Energy & Environmental Science, 2013
Electromechanical energy harvesting converts mechanical energy from the environment, such as vibration or human activity, into electrical energy that can be used to power a low power electronic device. Nanostructured piezoelectric energy harvesting devices, often termed nanogenerators, have rapidly increased in measured output over recent years.

Piezoelectric nanogenerators – a review of nanostructured piezoelectric energy harvesters

Nano Energy, 2015
Abstract A huge number of piezoelectric materials have been demonstrated since the discovery of piezoelectricity over a century ago. The use of nanostructured piezoelectrics, however, is a relatively recent development, and the understanding of the nanoscale size effects on ferro- and piezoelectricity is still being formulated.

r-Shaped Hybrid Nanogenerator with Enhanced Piezoelectricity

ACS Nano, 2013
Piezoelectric and triboelectric nanogenerators (NGs) have been proposed in the past few years to effectively harvest mechanical energy from the environment. Here, a polydimethylsiloxane (PDMS) layer is placed under the aluminum electrode of polyvinylidene fluoride (PVDF), thus forming an r-shaped hybrid NG.

A direct-write piezoelectric PVDF nanogenerator

TRANSDUCERS 2009 - 2009 International Solid-State Sensors, Actuators and Microsystems Conference, 2009
In this paper, we have successfully demonstrated the capability of a direct-write piezoelectric poly(vinylidene fluoride) (PVDF) nanogenerator using near-field electrospinning (NFES). Repeated and consistent output voltage up to 8.5 mV has been generated under an external strain of 0.092% from a single electrospun PVDF nanofiber, of which the output ...
