Description 1. To familiarise the students with materials used to replace part of a living system, or to exist in intimate contact with living tissue, and for minimally invasive surgical applications. 2. Students will understand biomaterial requirements, limitations and recent developments. | |||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Identify the characteristics and properties of the natural materials from which living systems are made. 2. Describe and explain the biological processes associated with the implantation of biomaterials in the body. 3. Identify, describe and explain models for the viscoelastic and/or rubber-like behaviour of artificial and natural biomaterials, and describe experiments to test these properties. 4. Identify, describe and explain relevant materials processing technologies, including polymer processing (e.g. extrusion), metal processing (e.g. casting) and coating technologies (e.g. PVD, CVD, Thermal Spray). 5. Analyse and solve linear viscoelastic problems (Maxwell, Kelvin models, Boltzmann superposition principle), soft tissue mechanics problems (simple finite elasticity models, prescribed deformations), fluid mechanics problems (polymer extrusion), and residual stress calculations (thermal spray coating processes) 6. Compile a well organised independent desk study on a biomaterial, including(i) writing a literature survey (ii) identification of key mechanical and physical properties required for a selected application, and (iii) biological evaluation of the biomaterial according to a relevant standard | |||||||||||||||||||||||||||||||||||||||||
