Poly (glycerol sebacate) (PGS) is a novel biocompatible elastomer in this scope. However this polymer has poor mechanical properties especially when the molar ratio of glycerol is higher than sebacic acid. Calcium Titanate (CaTiO₃) is a biocompatible ceramic with some degrees of piezoelectricity, which is in favor of cell growth.  In this study; Calcium Titanate is synthesized at nano-scale by sol-gel method and dispersed into as-synthesized PGS pre-polymer in weight-ratio of 5:95 for CaTiO₃ and PGS, respectively. This waxy material was cured to achieve the final product. The molar ratio of glycerol and sebacic acid for the synthesis of PGS was 1:0.8, respectively. X-ray diffraction (XRD) test confirms successful synthesis of CaTiO₃ and the nano-scale of crystals are approved by transmission electron microscopy (TEM) Image. Fourier transform infrared (FTIR) spectroscopy has revealed a chemical bond between the two </em><em>phases after addition of ceramic into pre-polymer. Distribution of CaTiO₃ nano-structures in the polymeric matrix is shown by Scanning Electron Microscopy (SEM).</em> https://www.ijnnonline.net/article_20406_9301216db7afbcde519bdc80e86e454b.pdf
