Abstract

The Zirconium and Titanium ceramic materials are used to make PZT (Lead zirconate titanate) piezoelectric ceramic composite. In this article, the Zirconium dioxide (ZrO2) and Titanium dioxide (TiO2) ceramic fillers with, ferroelectric polymer PolyVinyliDene fluoride-Tri Fluoro Ethylene (P(VDF-TrFE)) are utilized to make the ZrO2/P(VDF-TrFE) and TiO2 /P(VDF-TrFE) nano-composite thinfilm for flexible vibration energy harvester application. The scanning electron microscopes (SEM) with (Energy Dispersive Spectrometer spectrum) EDS examine the TiO2, ZrO2 fillers present in the composite. The ceramic fillers molecules Ti 2p and Zr 3d binding energy are confirm by X-Ray photoelectron spectroscopy (XPS). Each composite reaches their piezoelectric β- phases are confirm by Fourier Transform—Infrared Spectroscopy (FT-IR). The low surface roughness of the thin-film reaches more flexibility and deformation of a cantilever. The ZrO2/P(VDF-TrFE) composite is obtained low average surface value of 10 nm in the region of 50 µm is measured from Gwyddion software. The ceramic composite beam reaches their natural resonance frequency below 100 Hz is measure by Laser Doppler Vibrometer (LDV). The flexible cantilever beam nanogenerators produces peak-to-peak output voltage 8.2 V. The harvested output voltages are used at electronic devices and wireless sensor applications.

Summary

Introduction

The piezoelectric polymer plays an important roles in vibration energy harvester applications. The piezopolymer material has mechanically strong and it has high piezoelectric voltage constant because of this property piezo polymer vibration sensing are high compare with piezo-ceramics [1,2]. The most used polymer in vibration energy harvesting applications are PVDF(-(CH2/-CH2)n-) and its copolymer P(VDF-TrFE). In this paper presents the Nano-ZrO2 and Nano-TiO2 ceramic materials are utilized to fabricate the flexible piezoelectric vibration energy harvester application. The flexible vibration energy harvester fabricated form P(VDF-TrFE)/ZrO2 and P(VDF-TrFE)/TiO2) polymer composites. The well mixed P(VDF-TrFE) and ZrO2, TiO2 polymer composite solutions are casted on glass plate and get the 20μm thin film. In this thin-film placed on hot air oven at 140 ̊C for 1 hour. Silver electrode placed on top of the active layer using thermal evaporation method
