STRONG PIEZOELECTRIC ACTIVITY IN SIMULTANEOUSLY STRETCHED AND POLED POLY (VINYLIDENE FLUORIDE)

Design and Fabrication of Piezoelectric Β-poly(vinylidene Fluoride) Microactuators for Microfluidic Applications

This paper reports on a fabrication method for producing piezoelectric poly(vinylidene fluoride) films in their electroactive β-phase that features controlled thickness, smooth and flat surface, and high transparency. These films are suitable for being used as integrated microactuators, such as piezoelectric pumps and/or mixers, in microfluidic applications. -PVDF films with a thickness of abou...

Quantum Modelling of Poly(vinylidene Fluoride)

Human Mesenchymal Stem Cells Growth and Osteogenic Differentiation on Piezoelectric Poly(vinylidene fluoride) Microsphere Substrates

The aim of this work was to determine the influence of the biomaterial environment on human mesenchymal stem cell (hMSC) fate when cultured in supports with varying topography. Poly(vinylidene fluoride) (PVDF) culture supports were prepared with structures ranging between 2D and 3D, based on PVDF films on which PVDF microspheres were deposited with varying surface density. Maintenance of multip...

Multiferroic tunnel junctions with poly(vinylidene fluoride)

Ultra-Sensitive Strain Sensor Based on Flexible Poly(vinylidene fluoride) Piezoelectric Film

A flexible 4 × 4 sensor array with 16 micro-scale capacitive units has been demonstrated based on flexible piezoelectric poly(vinylidene fluoride) (PVDF) film. The piezoelectricity and surface morphology of the PVDF were examined by optical imaging and piezoresponse force microscopy (PFM). The PFM shows phase contrast, indicating clear interface between the PVDF and electrode. The electro-mecha...
