640-381 Principles and Applications of Sensors

Physics 640-141 plus 640-142 or 640-121 plus 640-122 or equivalent.

Electrical engineering 431-330 or physics 640-251 or equivalent.

This subject integrates the principles of physics and electrical engineering to introduce students to sensor technology. Students completing this subject will be able to:

• explain the fundamentals of the operation of sensors and transducers for the measurement of temperature, pressure, light, stress, composition, fatigue and the chemical environment; and

• design a solution to a particular sensing problem based on their knowledge of the physical principles underpinning the operation of each type of sensor.

In addition, students will enhance their ability to:

• participate effectively in a laboratory environment and be able to work on a project as part of a team; and

• plan effective work schedules and manage their time to meet the deadlines for submission of assessable work and preparation for tests and the examination.

Topics to be covered include the basic principles of the quantum theory of atoms, molecules and solids and the application of these principles to a wide range of materials which are of key importance in modern electronics and technology. In addition to the fundamental concepts, topics to be covered include an introduction to various types of sensors and the basic physical phenomena underpinning their operation.

A 3-hour examination (50%); projects totalling to an equivalent of no more than 3000 words (30%); laboratory work (20%).
