This review summarizes the current trends and developments in field of polyvinylidene fluoride (PVDF) for use mainly as a nanogenerator. The text covers PVDF from first steps solution mixing, through production, to material utilization, demonstration results, future perspective. Specific solvents ratios must be selected when choosing mixing solution. It is necessary set exact parameters during ...

Abstract Enhancing the electrical outputs of energy harvesters is a great demand for researchers in recent years. In this work, effect plasticizer treatment (Tetrahydrofuran [THF]) on ? phase content (F[ ]) electrospun polyvinylidene fluoride (PVDF) fiber webs which are used as active layers to directly make piezoelectric nanogenerator (PENG) demonstrated. The results showed that during treatme...

The rapid development of smart devices and electronic products puts forward higher requirements for power supply components. As a promising solution, hybrid energy harvesters that are based on triboelectric nanogenerator (HEHTNG) show advantages both high harvesting efficiency multifunctionality. Aiming to systematically elaborate the latest research progress HEHTNG, this review starts by intro...

Flexible piezoelectric nanogenerators for energy harvesting are getting more and attention nowadays by converting the mechanical to electric energy. Here, an environment-friendly nanogenerator based on regenerated cellulose (RC)/MoS2 nanosheet nanocomposite successfully exhibited a relative high output voltage of 2 V current 150 nA under slight press which were 5 7.5 times higher than those nea...

Research in the near future involves the integration of multi-functional nanodevices into selfcontained nanosystems with capabilities of sensing, controlling, communicating and actuating/responding. A nanosystem is composed not only of nanodevices but also a nanopower-source (or nano-battery). But the small size of the nano-battery significantly limits the battery lifetime. It is highly desirab...

We have applied the perturbation theory for calculating the piezoelectric potential distribution in a nanowire (NW) as pushed by a lateral force at the tip. The analytical solution given under the first-order approximation produces a result that is within 6% from the full numerically calculated result using the finite element method. The calculation shows that the piezoelectric potential in the...
