Question $4$

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

I. Vacuum deposition techniques and their application to thin film solution in

medical sensor fabrication.

II$.$ MEMS based fabrication techniques applied to healthcare sensor systems.

III. Antibody attached to Gold colloid within a paper matrix$-$based sensors and

associated fabrication techniques for the production of rapid clinical

diagnostics devices. Explain the principle of such a diagnostic mechanism.

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 rapid proto$-$typing related to sensing

developments, 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 Healthcare Sensing System

Development.
