BIOMENG 241 : Instrumentation and Design

Engineering

2023 Semester Two (1235) (15 POINTS)

Course Prescription

An introduction to engineering instrumentation related to the measurement of biological signals. Topics include: Fundamentals of measurement systems (electric circuits, basic electronics, frequency domain signal analysis and transient analysis, measurement systems). This course will cover the design methodology of instrumentation systems and include an instrumentation design project.

Course Overview

This is a required course for the biomedical engineering specialisation. There are two main lecture themes: instrumentation (basic electronics, semiconductors, operational ampliers, lter, digitisation, signal processing); and engineering design (teamwork, communication, safety and professional responsibility, software tools, material and manufacturing process selection). These themes are reinforced with laboratories, and applied in a group design project.

  5. Demonstrate an understanding of the principles and practice of engineering design and describe the major steps in the engineering design process. Design a biomedical instrument incorporating mechanical, electrical, and software. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 6.1 and 6.2)
  6. Demonstrate an understanding of teamwork. Work effectively as a team with other engineers and manage and discuss team and individual expectations. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1, 4.2, 4.3, 5.1, 5.2, 6.1 and 6.2)
  7. Demonstrate an understanding of design communication. Generate written reports and deliver an oral presentation summarising their team's instrument design. (Capability 4.1, 4.2 and 4.3)
  8. Demonstrate an understanding of safety and professional responsibility. Use failure mode and effects analysis and fault tree analysis to identify the possible hazards present in a design, as well as possible mitigation strategies. (Capability 5.1, 5.2, 6.1 and 6.2)
  9. Demonstrate an understanding of tools for instrumentation design: Use computer aided design software todesign mechanical components and electronic circuits. Use data acquisition software to measure and process biological signals. (Capability 1.1 and 3.2)
  10. Demonstrate an understanding of material, component, and manufacturing process selection. Choose real electronic components to meet design specifications, according to information from product data sheets. (Capability 1.1, 3.1, 3.2 and 5.1)

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect 16 hours of lectures, 16 hours of laboratories, 45 hours of group project work, 36 hours of reading and thinking about the content, and 37 hours of work on assignments, test, and examination preparation.

Delivery Mode

Campus Experience

Attendance is required at scheduled activities, including laboratories to complete components of the course.

Lectures will be available as recordings. Other learning activities including laboratories and tutorials may not be available as recordings. The course may include live online events including tutorials and group discussions.

Attendance on campus is required for the test.

The activities for the course are scheduled as a standard weekly timetable for the rst 8 weeks of semester, transitioning to a project-intensive schedule for the remaining 4 weeks.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Health & Safety

Students are expected to adhere to the guidelines outlined in the Health and Safety section of the Engineering Undergraduate Handbook.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

Students appreciated that no lectures were scheduled in the final 4 weeks of semester, enabling them to focus on the group project. In response to students' requests, we will provide more worked examples related to the lecture content. Some students felt that the project brief was too open-ended, lacking explicit instructions about what should be accomplished by when. We will revise the document for 2023.

Other Information

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available). Please remember that the recording of any class on a personal device requires the permission of the instructor. Piazza will be used for class discussion. The system is designed to get you help quickly and eciently from classmates, teachers, and teaching assistants. Rather than emailing questions to the teaching sta, you are encouraged to post your questions on Piazza.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
