The aim of this research is to characterize the biomaterials for different implant applications in human body. Biomaterials have been used in different parts of human body such as hips, bones, joints, stents, etc. As these materials are using in different parts of human body, they need to represent properties compatible to the required part which is called biocompatibility. Even the expectations of the patient and doctor from the biomaterials implantation surgery can seriously affect the selection of biomaterials. For an instance, if the patient is too old, they may need to use a biomaterial that may dissolve in human body thus the second surgery for implant removal can be eliminated for the patient convenience. The selection of biomaterials that can offer suitable properties is of high significance. In some cases, they need to be tough like bones and joints with enough stiffness. In some implantations, they need to be flexible like stents for heart valves. In some of the cases, they need to be anti-corrosion due to the hostile environment in human body fluid. On the other hand, in some cases they need to dissolve in human body to eliminate the implantation removal surgery. Furthermore, it seems necessary to evaluate the biomaterials based on their fatigue life because they are subjected to cyclic loads in human body. The objective of this study is to characterize the properties of different biomaterials that can help the doctor and the patient to select the best biomaterials based on their expectations from the implantation surgery.
