Brief Handbook Description: Biomedical engineering is being deeply reshaped by the advancements in computational tools and the utilisation of rich data. This unit will explore the processes involved in designing and building systems to perform computational analysis on biological signals, using microcontrollers and desktop or server computing. The main teaching activities will focus on the theory and practical skills for data capture, cleaning, communication, storage, and analytics. The purpose is to ensure that students develop the skills necessary to design systems that can be used for monitoring of patients, where the data can be used for analytics, e.g. prediction of an adverse event. This is relevant to a number of applications in modern healthcare such as continuous and remote monitoring devices. The unit will develop core skills in programming, solution design, sensor interfacing, and data analysis.
Assumed Knowledge: Knowledge of basic biomedical engineering principles (BMET1960) and basic programming (ENGG1801 or ENGG1810 or ENGG9810 or INFO1110).

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
Students are required to explain the mathematical theories behind biomedical signal analysis pipelines, both in laboratory exercises and in assessments. Based on this understanding, students will have to implement the appropriate software and hardware components to solve particular signal processing tasks. (1) Maths/ Science Methods and Tools (Level 2)
Students are given scenario(s) that require them to use various components and tools to create a pipeline to capture, transmit, analyse, and visualise biological signal data. Students have to implement an appropriate pipeline given the specific scenario. (2) Engineering/ IT Specialisation (Level 3)
In laboratory assignments and assessments, students are required to integrate hardware and software components to create solutions for remote patient monitoring tasks. (3) Problem Solving and Inventiveness (Level 2)
Students produce the design of a pipeline for biomedical signal analysis. They will describe the integration of various hardware and software components, identifying both strengths and limitations of their proposed design. (4) Design (Level 2)
Students are required to practice their written and oral communication skills through the assessments. They need to articulate the technical means through which their practical assessment meets the requirements of the scenario, and the justification for their design decisions. (6) Communication and Inquiry/ Research (Level 3)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Assessment Description: • Assignment: Design Proposal – students will propose a design for a system which collects data from a (supplied) biomedical sensor and displays the data in a simple graphical format on a host computer. The report will describe the system and software architecture, key system performance requirements, and provide a plan (schedule, risks, issues) for the implementation of the system.

• Quiz – a mid-semester quiz covering materials from lectures, tutorials, and laboratories.

• Assignment: System Demonstration – in a group, students will present the realisation of their design and justify the design choices that they have made.

• Assignment: Design Report – students will provide a brief report on the system operation and performance, as well as comparing the realisation of the system to the design proposal.

• Lab: Contribution – students will keep a logbook that details their contribution to each week's laboratory exercises and the lessons they have learned.

• Written exam: Final examination covering all materials in lectures, tutorials, laboratories, and assignments.
Assessment Feedback: The teaching team will provide feedback on the assessment tasks. Assignment results will be published on Canvas. Students are required to check their results. Any errors or omissions must be reported to the unit coordinator, with appropriate evidence, within 5 working days (a week) of being published; 5 days after being published, marks are considered to have been confirmed and will not subsequently be altered.
