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.
