Description including Unit Aims

The unit focusses on the typical aspects of biomedical sensing and stimulation and its instrumentation. A major part of the course is dedicated to the sensors and their specific requirements for use in biomedical applications.

Outline syllabus:

Sensors for biomedical applications: Sensor principles and transducers phenomena

Mechanical sensors: strain sensing, pressure sensors, accelerometers

Silicon micromachining techniques, Temperature, photo and magnetic sensors

Biochemical sensors: dissolved oxygen, glucose, ureum;

Bioelectric potentials and stimulation techniques: Biopotentials: ECG, EMG, EEG;

Optical sensors: Optical fiber, absorption measurement, fluorescence measurement, bioluminescence and chemiluminescence's, optical sensor for pH, pO2 and pCO2 measurement.

Measurement techniques, the right leg drive, Stimulation principles, Biomedical stimulation: nerves, muscles, cochlea, heart;

Implantable electronic systems: Biotelemetry: specific requirements, Examples of active and passive telemetry systems.

Intended Learning Outcomes

Students should be able to:-

1. Explain the working principles of the various types of biosensors studied.

2. Describe the construction of biosensors.

3. Discuss the in vitro and in vivo operation and application of biosensors.

4. List the problems likely to be faced in biosensor construction such as biocompatibility and biomaterials used, and future application of biosensors.

5. Test and analyse lab experiment results to design a biosensor.
