Tunable Pseudo-Piezoelectric Effect in Doped Calcium Titanate for Bone Tissue Engineering
CaTiO<sub>3</sub> is a promising candidate as a pseudo-piezoelectric scaffold material for bone implantation. In this study, pure and magnesium/iron doped CaTiO<sub>3</sub> are synthesized by sol-gel method and spark plasma sintering. Energy dispersive X-ray mapping confirm t...

CaTiO<sub>3</sub> is a promising candidate as a pseudo-piezoelectric scaffold material for bone implantation. In this study, pure and magnesium/iron doped CaTiO<sub>3</sub> are synthesized by sol-gel method and spark plasma sintering. Energy dispersive X-ray mapping confirm the homogenous distribution of doping elements in sintered samples. High-energy X-ray diffraction investigations reveal that doping of nanostructured CaTiO<sub>3</sub> increased the strain and defects in the structure of CaTiO<sub>3</sub> compared to the pure one. This led to a stronger pseudo-piezoelectric effect in the doped samples. The charge produced in magnesium doped CaTiO<sub>3</sub> due to the direct piezoelectric effect is (2.9 ± 0.1) pC which was larger than the one produced in pure CaTiO<sub>3</sub> (2.1 ± 0.3) pC, whereas the maximum charge was generated by iron doped CaTiO<sub>3</sub> with (3.6 ± 0.2) pC. Therefore, the pseudo-piezoelectric behavior can be tuned by doping. This tuning of pseudo-piezoelectric response provides the possibility to systematically study the bone response using different piezoelectric strengths and possibly adjust for bone tissue engineering. |
