Brief Handbook Description: | Implantable microelectronic devices functioning either as nerve stimulators or nerve blockers comprise one of the largest markets in the global medical device industry. The aim of this unit of study is to give students a complete overview of the underlying technology (microelectronics, encapsulation biomaterials, electrode biomaterials, electrode-neural interactions, inductive power systems and data links, signal processing) and an expert review of the major technological applications on the market, which include Cochlear implants, pacemakers and implantable defibrillators, deep brain stimulators, pain control nerve blockers, bionic eye implants, functional electrical stimulation systems. The unit will also review emerging applications such as gastrointestinal disorders, obesity; vagal nerve stimulation - epilepsy, depression, carotid artery stimulation – hypertension, spinal cord stimulation - ischemic disorders, angina, peripheral vascular disease, incontinence, erectile dysfunction. The unit will conclude with a snapshot of the future: “brain on a chip” progress, nerve regrowth, neurotropins, drug/device combinations. This is a Master of Professional Engineering Unit of Study intended for biomedical engineering students with an interest in working in the medical device industry in the large market sector area of implantable electronic devices. |

T&L Activities: | The unit will be structured around the major elements of neuromodulation, the underlying technology and the applications current and future. The primary teaching delivery method will be lectures, including a weekly quiz on the previous week’s lecture. Each student will also do an independent research project. There will be 3 hours of lectures per week. Another 5 hours per week outside of formal contact hours will be needed in order to successfully complete assignments and study. |
Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
Attribute Development Method | Attribute Developed |
The primary purpose of this unit is to build on the engineering and science fundamentals that the students already have (electronics, biology, chemistry, materials science, and engineering design) and apply them to the engineering specialisation of neuromodulation. Specific skills will be bioelectronics, neuroscience and neuro-engineering, implantable medical device technology using implantable medical devices. | Engineering/IT Specialisation (Level 5) |
Techniques methods and tools will be acquired for analyzing the complex mathematical, neurobiological, and electronic analysis underlying the function of neuromodulation devices and their interaction with the human neural system. | Maths/Science Methods and Tools (Level 3) |
Individual research project on an aspect of neuromodulation. | Information Seeking (Level 3) |
Students will develop this attribute through writing a report and preparing a poster from the research project on an aspect of neuromodulation. | Communication (Level 4) |
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Assessment Description: |
Written exams: 10 closed-book quizzes, 15 minutes each, will be held in weeks 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 respectively, based on the lecture material of the previous weeks. These quiz marks in total will comprise 40% of the course assessment. An individual research report (Week 13) and Individual Poster Presentation (Week13): Students will be given individual topics related to neuromodulation early in the semester. They will be required to research the topic, prepare a 5 page research reports (single spaced 12 point arial font, references and appendices are in addition to the 5 pages), and prepare an individual poster presentation and attend and discuss their poster at a poster session to be held at Cochlear’s Headquarters at 1 University Drive, Macquarie University. As an industry outreach event for the students, Cochlear and other staff will be invited to attend the session, and discuss the posters with the students. The poster (30%) and research report (30%) will be marked by the course teaching team and the in-session exam/quiz marks will comprise 40% of the entire course assessment. The ten 15 minute quizzes are equivalent to a 3 hour examination. There is no final examination. Note: Reports will be required to be adequately referenced and acknowledged according to the academic honesty policy linked to below. Text-matching software used for detecting plagiarism will be employed. |
