This module is intented to enhance fundamental and critical understanding of functionalities of structural materials used to construct microsystems (MEMS in short) and to apply them in developing MEMS devices.
It will also discuss and evalute unique properties, advantages and limitations of smart material for MEMS applications.
It will provide general knowledge of biomaterial, their uniqueness and an understanding of how biosensors work and function.
The acquired knowledge and skills would assist in selecting the best or most appropriate materials for the development of MEMS and sensors.

Engineering material selection for microsystems
An intensive course of lectures and workshops over 5-10 days will be used to introduce the students to the subject matter. Each student will be provided with a structured learning package in order to develop their knowledge, comprehension and application of the material presented.
This module will be assessed by completion of all the assignments which must be submitted after three months, as a pieces of work consisting of three parts, a, b and c of increasing depth and application. Candidates will have access to tutors throughout this preparation phase. This will allow formal feedback during the remote / distance learning part of the module. The assessed work is also required to be orally presented.
