Piezoelectric Nanogenerators

Self-polarized piezoelectric devices have attracted significant interest owing to their fabrication processes with low energy consumption. Herein, novel poling-free piezoelectric nanogenerators (PENGs) based on self-polarized polyvinylidene difluoride (PVDF) induced by the incorporation of different surface-modified barium titanate nanoparticles (BTO NPs) were prepared via a fully printing process. To reveal the effect of intermolecular interactions between PVDF and NP surface groups, BTO NPs were modified with hydrophilic polydopamine (PDA) and hydrophobic 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES) to yield PDA-BTO and PFD-BTO, respectively. This study demonstrates that the stronger hydrogen bonding interactions existed in PFD-BTO/PVDF composite film comparative to the PDA-BTO/PVDF composite film induced the higher β-phase formation (90%), which was evidenced by the XRD, FTIR and DSC results, as well as led to a better dispersion of NPs and improved mechanical properties of composite films. Consequently, PFD-BTO/PVDF-based PENGs without electric poling exhibited a significantly improved output voltage of 5.9 V and power density of 102 μW cm−3, which was 1.8 and 2.9 times higher than that of PDA-BTO/PVDF-based PENGs, respectively. This study provides a promising approach for advancing the search for high-performance, self-polarized PENGs in next-generation electric and electronic industries.

Piezoelectric Nanogenerators

With the development of science and technology, the smaller sizes generator, the more attention by people. The main purpose of this article is to manufacture piezoelectric nanogenerator under micro vibration and its working principle is introduced and its performance is studied. The results show that, using the present nanomaterials, piezoelectric materials can be prepared. When its wind in copper laps, under the situation of micro pulse vibration its can turn into electrical energy, thus yield piezoelectric nanogenerators. In ambient vibration condition, piezoelectric materials produce larger rated current and voltage. However, copper laps cutting magnetic line of force produce less rated current and voltage. So the piezoelectric nanogenerators can be separately used to supply power. If multiple piezoelectric nanogenerator in tandem may produce higher voltage, current and power, which possess commercial value.

Piezoelectric Nanogenerators

This paper reports advancement in bringing flexible piezoelectric nanogenerators (NGs) closer to being realized in a commercial market. We have adopted a method to synthesize piezoelectric ZnO nanorods (NRs) on any electrically conductive surface without a seed layer or a specially selected substrate with matching lattice spacing. By contacting a metal with a dissimilar electro-negativity, a galvanic cell is created in the electrolyte growth medium. We have demonstrated the performance of the as grown NRs on a thin NG using common PET film. The device produced voltages in excess of three times higher than a parallel fabricated reference sample under bending loads.

Abstract In recent years piezoelectric nanogenerators, due to their more durability in high dust or humidity are more attractive than triboelectric ones. So, increasing their outputs is the subject of much researches. I focused on electrodes of the acoustic nanofibers nanogenerators for the first time. Here, I introduced a new electrode that is cheaper and does not result in lower outputs. Here for the first time graphene spin-coated ink was used for polyacrylonitrile-based acoustic nanogenerator. The results of the tests compared with the in-situ synthesis of nickel nanoparticles on the layer and using graphene spin-coated screen ink and conductive tapes. Finally, producing sound by this graphene ink was done too.
