Conduct an investigative survey in an R&D technology firm

Your manager in an R&D technology firm asked you to conduct an investigative survey and test your assertions on the following and provide a report.

1. Part A

Investigative exercise on Capacitive Sensing Circuitry

There are numerous sensing elements that changes the capacitance in response to a certain physical parameter of interest; such as humidity, touch, soil moisture etc.

(How we translate the change in capacitance to a value readable by an analogue to digital converter.)

1. Investigate how capacitive measurement works and what can be measured using
2. Investigate what mechanisms are there to sense capacitance using a circuitry
3. Explain them in detail and show how the output of the circuit changes in response to a change in
4. BONUS: Model and test one of the circuits using MATLAB Simulink using the output range of a real capacitive sensor found on com as your capacitive range.

Your report (1000 word) will consist of:

• An explanation on the technique of Capacitive sensing 10 Marks
• An investigation into the transduction 10 Marks
• A detailed explanation on one of the circuits 10 Marks
• Relevant References and structure 5 Marks
• MATLAB simulations 5 Bonus Marks

MATLAB files that generated the results should be submitted as a separate executable file or in the appendix.

2. Part B

Investigative report on Wireless Sensor Networks

Wireless sensor networks can be used to capture information using appropriate sensors and the data can be processed by algorithms implemented in the cloud. The outcomes of these analytics can be made available to the interested parties via applications on mobile devices.

You are expected to conduct an investigative exercise on: motion capture wearable sensors collecting human movements and the data processed by relevant algorithms implemented in the cloud for extracting specific motion patterns of interest. The overall exercise is expected to use the ideas conveyed through the lectures in addition to the investigative research you are expected to conduct.

It should cover the state of the art in this space and will entail conducting an extensive literature survey on the relevant concepts (outlined in the lectures and practical works) and your ability to uncover relevant information, articulate and report at a professional level is tested. The Rubric associated with the assignment can also be used as a guide.

Word limit of 2,000 including references should highlight the following aspects

• Background and motivations 10 Marks
• Problem formulation 5 Marks
• Technical complexities areas of specific interest 20 Marks
  1. Sensing
  2. Data transmission
  3. Cloud implementations
  4. Analytic techniques
• Data handling issues (Security and Privacy) 10 Marks
• Meeting industry standards 5 Marks
• Discussion of different approaches 5 Marks
• Conclusions
