Module code: ENGM186

Module Overview

This module introduces the student to the basic concepts of instrumentation, with a focus on medical instrumentation. It provides a critical understanding of the principles underpinning medical equipment development.

The student is required to conduct a mini project in which an appropriate initial design of a measuring system for a specific medical signal is presented, explained, and discussed. Synthesis of information from the lectures supplemented with the review of relevant literature is an essential part of the project.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of medical instrumentation principles as well as the ability to analyse analogue and digital electronic circuits in the final examination. The coursework assignment allows students to demonstrate their knowledge and understanding of the fundamental concepts of medical instrumentation, presenting, explaining and discussing an appropriate initial design of a measuring system for a specific medical signal. Synthesis of information from the lectures, supplemented with the review of relevant literature is an essential part of the project.

Thus, the summative assessment for this module consists of:

·         Coursework    [Learning outcomes 4, 5, 6, 7, 8, 10] (40 hours)       Deadline W11 {40%}

·         Examination   [Learning outcomes 1, 2, 3, 4, 7, 9]    (2 hours)                                 {60%}


Formative assessment and feedback

·         Formative verbal feedback is given in tutorials

·         Formative Multiple Choice Tests are available on SurreyLearn to give feedback on the understanding of circuits and instrumentation principles

·         Written feedback is given on the coursework assessment

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce basic medical instrumentation principles through theory with worked examples. This is delivered principally through lectures and tutorial classes. In the latter students will have to design and simulate electronic circuits with Multisim.

The learning and teaching methods include:

  • 2 hours of lectures per week x 10 weeks

  • 2 hour Multisim-based tutorials x 10 weeks

  • 2 hours revision lecture


Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
