Abstract

Piezoelectric materials are materials that convert electrical energy into mechanical energy (acoustic), and vice versa, with mechanical pressure on them, electrical energy is produced. The use of lead-free piezoelectric materials in the bone is developing due to its piezoelectric properties. The aim of this study was to investigate the piezoelectric property of barium titanate. Barium Titanate is a bioactive material that is suitable for use in bone tissue engineering. In barium ceramics, non-polar titanate, ferroelectric regions are randomly oriented, and thus the piezoelectric properties are minimal. Therefore, there is a need for polarization to increase piezoelectric properties. For this purpose, this study was carried out by polarization with different voltage and time on two groups of implantation and porous scaffolds. The implants of various sizes with different voltages and times are polarized in oil, and finally their piezoelectric properties were examined by the piezo test and compared with each other. Also, three-dimensional scaffolds with a porosity of 80% were made using foam casting method. The scaffolds were then polarized in the oil at a different voltage and time, and finally their piezoelectric properties were examined by the piezo test. Mechanical properties tests were carried out on both groups and then MTT test were performed to examine the effect of piezoelectric properties on cell growth. Finally, it was concluded that both implants and porous scaffolds with piezoelectric properties can find the proper properties for use in bone tissue engineering. It was also concluded that higher diameter and the lower height of the implants makes greater piezoelectric coefficient. Also, the results of cellular testing confirmed the effect of piezoelectric properties on bone growth.
