Piezoelectric nanogenerator using CdS nanowires

Applied Physics Letters, 2008
Vertically grown cadmium sulfide (CdS) nanowire (NW) arrays were prepared using two different processes: hydrothermal and physical vapor deposition (PVD). The NWs obtained from the hydrothermal process were composed of alternating hexagonal wurtzite (WZ) and cubic zinc blende (ZB) phases with growth direction along WZ ⟨0001⟩ and ZB [111].

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.

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.

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.

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 ...

Instantaneous piezoelectric nanogenerator for pacemaker applications

Nano Energy
Implantable nanogenerators (NG) are a promising solution to the self-sustainable power source for cardiovascular implantable electronic devices (CIEDs), such as pacemakers, by harvesting biomechanical energy from heartbeats. Nevertheless, the conversion efficiency of mechanical energy into electrical energy has long been a significant challenge ...

Highly sensitive stretchable transparent piezoelectric nanogenerators

Energy Environ. Sci., 2013
Here we report a new type of stretchable transparent piezoelectric nanogenerator (NG) using an organic piezoelectric material consisting of poly(vinylidene fluoride trifluoroethylene) [P(VDF-TrFE)] sandwiched with mobility-modified chemical vapor deposition-grown graphene electrodes by ferroelectric polarization into P(VDF-TrFE).

ZnS-paper based flexible piezoelectric nanogenerator

AIP Conference Proceedings, 2018
Here, we presented a novel, cost effective approach to fabricate flexible piezoelectric nanogenerator (NG) consisting of ZnS nanowires (NWs) grown upon cellulose. An output voltage of 4 V is generated from the nanocomposite paper (NC-paper) based NG. Subsequently, it has the capability to power Light Emitting Diode (LED) and charging up capacitor.
