Q$4.$ Q$4$ contains $3$ parts a$),$ b$)$ and c$)$ shown below. Please answer all parts.

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

I. Thick Film based techniques and their application to electrode solutions in

medical sensor fabrication.

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

III. Gold colloid based Lateral Flow devices based.

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

will be brought to medical diagnostic devices.

$(9$ marks$)$

b$)$ Discuss, with examples, the use of UX$,$ Living Labs and rapid proto$-$typing that

relates to the development of various sensing platforms. Highlight the use of new

Arduino's, additive manufacture, $3-$d printing, App$/$GUl 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 role of Machine Learning in improving patient pathways within a

hospital setting. Also reference and explain how Internet$-$of$-$Things $($IOT$)$ type

devices will play an important role in gathering patient data to allow machine

learning to robustly play a role in patient pathways.
