Outline

Overview

This unit teaches the student how to recognize where and how their theoretical skills can be applied to practical situations in the field of mechanical design. As a case study, a set of widely implemented Micro-Electro-Mechanical Systems (MEMS) is introduced, including Pressure Sensors, Microphones, Accelerometers, Gyroscopes and Micromirrors. Selected mechanical designs are presented and design choices are discussed with respect to their performance. Notions specific to microfabrication and the concept of scaling laws are introduced and elucidated at commonly implemented examples. The unit includes a hands-on design and modelling part introducing modern multi-physics finite element analysis. Dedicated tutorial sessions introduce the finite element modeling of Micro-Electro-Mechanical Systems. An emphasis is laid on the capability to couple multiple physics in a single model, including deformation of solids by electrostatic, electromagnetic or electro-thermal forces. The students will learn how to conceive and engineer a MEMS design, and predict performance by multi-physics finite element analysis.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	creative novel and effective process
Distinction	75 - 84	very thorough work with lateral consideration
Credit	65 - 74	excellent application to moderate problems
Pass	50 - 64	applied basic principles to simple problem
Fail	0 - 49	When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

Deduction of 5% of the maximum mark for each calendar day after the due date.
After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

5% per day for up to ten calendar days, after which a zero mark will be awarded

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.
