Teaching Methodologies
The teaching methodology is developed through theoretical classes, using slides, accompanied by the presentation and development of the topics forming the syllabus. The theoretical-practical classes are dedicated to solving problems related to the study of the properties of the various materials classes. They aim to consolidate the themes covered in the theoretical classes. Student participation is strongly encouraged by the interaction promoted by the teacher.
The slides and problem sheets are previously made available to students on the academic platform InforEstudante.
The course assessment consists of a final exam.
Learning Results
The aim of this course is to provide students with concepts about the structure, function, and properties of the various material
types important in Bioengineering. The objectives to be achieved by students who attend this course include:
1. know and understand the basic principles of materials science (atomic bonding, crystal structure, phase, etc.);
2. acquire the ability to classify any material in its class (metals, polymers, ceramics and composites);
3. relate the most relevant properties of the material types to their nature and specific bioengineering applications;
4. know and understand the most relevant tissue-biomaterial interactions.
