MATL06007 2019 BIOMATERIALS AND MEDICAL DEVICES
This is an introductory module covering concepts in Materials Science and Materials Engineering that may be of relevance to biomedical science and medical biotechnology. The content is framed in the context of the selection and suitability of materials used in biomedicine and in medical devices.
On completion of this module the learner will/should be able to;
Define basic concepts and explain general principles of materials science.
Describe, discuss and use examples of how the structure of materials influences the properties and performance of materials and apply knowledge of basic material science to identify material properties that are critical for metallic, polymer and ceramic biomaterials, or their combination.
Explain the operation of a range of instruments in materials testing and examination.
Report the performance of a materials science experiment and/or test in a prescribed manner, presenting results, processing and interpreting data, and deducing informed conclusions.
Research, analyse, interpret and report information relevant to function and construction of biomedical devices and describe the relevance of the choice of biomaterial for given applications.
Teaching and Learning Strategies
This module will be delivered full-time in a face-to-face classroom environment. Theory wil be taught in a lecture setting 2 hrs per week. Laboratory teaching will take place every week in a 2 hour session. Learners will augment face-to-face class time with independent learning.
Module Assessment Strategies
A written reports in the form of a short essay will be assigned during the module to assess the learner's progress in understanding the fundamental concepts of materials science and interpreting these concepts in the context of biomedical applications. The assignments will normally be scheduled before the mid point of the semester to encourage early and consistent engagement with the module, to monitor progress and provide feedback.
A group presentation exercise focussing on medical devices will be scheduled towards the end of the module. This is to encourage the learners to demonstrate a knowledge of materials science in the context of medical device applications . The exercise will also promote peer assisted learning of the basics of a wide range of medical devices and will enable learners to demonstrate team-working and presentation skills.
Towards the end of the semester learners will take a short summative quiz. The purpose of the quiz is to encourage learners to engage with the totality of the course material well in advance of the terminal exam and to afford them the opportunity to assess their integrated understanding.
Laboratory skills and report-writing ability will be assessed weekly as part of the practical work performed during the module.
An end of semester terminal written exam will be used to assess the learner's integrated understanding of the module.
Learners must reach an assigned gate of 30% of the available marks in the end of semester terminal exam and achieve at least 40% overall to pass the module.
Learners must attend at least 75% of the available practical sessions to pass the module.
Repeat assessments will be of the same kind as any failed elements and can include any required combination of repeat final exam, repeat practical exam, and/or repeat quiz. Under certain circumstances the learner may be required to repeat attend the module.

Explores Biomedical Science from a Unique Perspective Biomaterials: A Basic Introduction is a definitive resource for students entering biomedical or bioengineering disciplines. This text offers a detailed exploration of engineering and materials science, and examines the boundary and relationship between the two. Based on the authors course lecture notes and many years of research, it presents students with the knowledge needed to select and design biomaterials used in medical devices. Placing special emphasis on metallic, ceramic, polymeric, and composite biomaterials, it explains the difference between materials science and materials engineering, introduces basic concepts and principles, and analyzes the critically important properties of biomaterials. Explains Complex Theories Using Aspects of Daily Life This text provides an appropriate balance between depth and broadness of coverage, and offers an understanding of the most important concepts and principles to students from a wide academic spectrum. It delivers the science of biomaterials in laymen terms, from a material standpoint, as well as a clinical applications point of view. It equips students majoring in materials science/engineering with knowledge on the fundamentals of how biomaterials behave at a biological level, and provides students majoring in medicine with information that is generally unavailable in traditional medical courses. The authors incorporate learning objectives at the beginning of each chapter, as well as chapter highlights, problems, and exercises at the end of each chapter. In addition, they present objectives, suggested activities, and reference material for further reading.
