Electro-spun piezoelectric PLLA smart composites as a scaffold on bone fracture: A review.

The intrinsic ability of these scaffold materials to generate piezoelectric currents presents a major proposition for increasing the complexity of the scaffold and facilitating tissue healing. The piezoelectric behavior of bone tissue has been an area of interest for many researchers in the past. However, these properties have not been given much attention in new osteochondral tissue scaffold designs, whereas the established design factors mainly concentrate on the structural and mechanical characteristics of the tissue in question.

Piezoelectricity performance and β-phase analysis of PVDF composite fibers with BaTiO and PZT reinforcement.

Piezoelectric composite fibers have various applications such as energy harvesting and human body monitor devices. Therefore, the construction of fibers that have the highest piezoelectric efficiency while using materials with the least toxicity is of great importance for health. Consequently, in the research a head PZT/PVDF (Lead Zirconate Titanate/Polyvinylidene fluoride) and Lead free BaTiO/PVDF (Barium Titanate/Polyvinylidene fluoride) 0-3 connection type composites nanofibers were fabricated by Electrospinning method.
