About this subject
This subject integrates the principles of physics and
electrical engineering so that upon completion of the subject students
will understand the fundamentals of the operation of sensors and
transducers for the measurement of temperature, pressure, light,
stress, composition, fatigue and the chemical environment. Students
will be able to design a solution to a particular sensing problem based
on their knowledge of the physical principles underpinning the
operation of each type of sensor.
Fundamentals 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 sensor technology.
Using these fundamental ideas, the topics to be covered
include introduction to various types of sensors and the basic physical
phenomena underpinning their operation; chemical sensors; pressure
sensors; temperature sensors (remote and contact); light sensors
(including photodiodes, photomultipliers, CCD cameras, and optical
fibre sensors); examples and applications; signal processing for
sensor; and sources of error and limitations.
