BIOMEDICAL SENSORS AND SIGNALS - 2025/6

Module code: ENGM262

Module Overview

This module describes the use of equipment (such as electroencephalography and electrocardiography among others) and technology to measure important information about the physiological state of a patient that may be used in diagnosis or patient monitoring. The module also provides the student with an up-to-date knowledge base on the theory and professional practice of engineering applied to the rehabilitation of people with sensory and neurological disability.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies, and mathematics methods as well as the ability to describe particular systems and processes in the final examination. Thus, the summative assessment for this module consists of:

Coursework               [ Learning outcomes 1, 2, 3, 4, 5 ]                                                                  

Examination               [ Learning outcomes 1, 2, 3, 4, 5 ]          (2 hours in a 4 hour window)          

Formative assessment and feedback will be provided throughout the module.

Module aims

  • Specialist knowledge about the use of apparatus and procedures in order to measure the physiological state of a subject, and the associated procedures in order to ensure the safety of that subject in a healthcare setting.  
  • An up-to-date knowledge base on the theory and professional practice of engineering applied to the rehabilitation of people with sensory, neurological or communication disability.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

The principal teaching approach is through the delivery of formal lectures and different demonstrations relevant to physiological measurement. 

The learning and teaching methods include face-to-face lectures and captured content.

 

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.

Other information

The School of Mechanical Engineering Sciences is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas: 

Digital capabilities: The students will use appropriate technology to complete authentic assignments including Microsoft Office software and MATLAB. Students will also use interactive formative tools to conclude and recall learning (unassessed) in lecture sessions.  

Employability: Students will be supported to develop their knowledge of devices and technologies used by biomedical engineers in the field. Throughout the teaching of this module, the deliverer will introduce provisions that persons undergoing physiological testing or persons with disabilities may receive from the National Health Service or private companies. This will afford students the opportunity to consider what various biomedical applications there are in the UK and abroad, which companies are active in the production of various devices and to consider whether these are areas of interest for career pursuits. Students will also have the opportunity to consider research carried out at the University of Surrey in the hopes that this will give insight into ‘what comes next’ after an undergraduate degree.  

Global and Cultural capabilities: Students will learn about the prevalence of disease and disability with respect to the medical devices and sensors seen in this module. Students will be encouraged to consider the experience of device users and to understand what the various gains and risks would be for a user of each device.  

Resourcefulness and resilience: Through participation in regular unassessed formative activities, students will develop their fluency and recall of information delivered throughout the module, building resilience and a growth mindset.
