In this paper, we report a technique that uses piezoelectric polyvinylidene fluoride (PVDF) microbelts to convert the energy from low-speed air flow to electricity via their resonant oscillation. The micrometre thick PVDF thin films were fabricated by a top-down reactive ion etching process, where the thickness was controlled by etching time and the piezoelectric phase was well preserved. The t...

Electrospinning was employed to prepare new multi-functional nanowebs. Cyclodextrin based inclusion complex (CD-IC) was used to disperse multiwalled carbon nanotubes (MWNT) within electrospun polyvinylidene fluoride nanofibrous membranes (PVdF-NFM). Subsequently, MWNT(CD-IC)/PVdF-NFM was loaded with gold (Au) particles. The morphology, structure and thermal properties of Au/MWNT(CD-IC)/PVdF-NFM...

Lead zirconate titanate (PZT) thick films with uniformly dispersed submicrometer pores were successfully fabricated on platinized silicon substrates with various thicknesses ranging from 1 lm to over 100 lm by aerosol deposition. Mixed powders of PZT and polyvinylidene fluoride (PVDF) were deposited for initial fabrication of composite films. After burn-out of the PVDF phase from the composite ...

In this paper, two different piezoelectric transducers-a ceramic piezoelectric, lead zirconate titanate (PZT), and a polymeric piezoelectric, polyvinylidene fluoride (PVDF)-were compared in terms of energy that could be harvested during locomotion activities. The transducers were placed into a tight suit in proximity of the main body joints. Initial testing was performed by placing the transduc...

Improvement of the binding of polypyrrole with PVDF (polyvinylidene fluoride) thin film using low pressure plasma was studied. The effects of various plasma gases i.e., Ar, O₂ and Ar + O₂ gases on surface roughness, surface chemistry and hydrophilicity were noted. The topographical change of the PVDF film was observed by means of scanning electron microscopy and chemical changes by X-ray photoe...
