Question $4$

$($A$)$ What do you understand by the following terms:

a$)$ Semiconductor based techniques and their application to thin film solutions in

medical sensor fabrication.

b$)$ Micromachined based fabrication techniques applied to healthcare sensor

systems.

c$)$ Antibody attached to Gold colloid within a paper matrix$-$based sensors and

associated fabrication techniques for the production of rapid clinical diagnostics

devices called lateral flow devices. Explain the principle with diagrams, of such

a diagnostic mechanism and its applications.

Use diagrams to illustrate your answers and explain the significant benefits that

will be brought to medical diagnostic devices.

$($B$)$ Discuss, with examples, the use of new ideation to proto$-$type systems related to

the development of sensing platforms, including the use of new microprocessor$-$

based platforms $($such as Arduino, raspberry$-$phi etc.$)$; additive manufacture, $3-$d

printing, App$/$GUI interfaces for mobile$/$cloud$-$based platforms and low latency

wireless systems. Provide an example of how such an approach is changing the

productivity of the development phases of a Healthcare Sensing System.

$($C$)$ Discuss the use of cloud analytics and the role of data analytics & artificial

intelligence in improving patient pathways during illness. Also reference how

Internet$-$of$-$Things $($IOT$)$ type devices will play an important role in gathering

patient data.
