Fourth Year Project

Current Project (2018-2019): Li-Fi Wireless Communication System

Li-Fi stands for Light Fidelity. It is a technology for wireless communication between devices using light to transmit data and position using LEDs (either the visible or the infrared LEDs). Compared to the commonly used Wi-Fi wireless communication technology, the key technical difference is that Wi-Fi uses radio frequency to transmit data. Li-Fi has several advantages such as offering higher bandwidth and higher transmission speeds, and the ability to work in areas susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals) and offering higher transmission speeds. One interesting aspect of Li-Fi is its application in shorter range/distance without any physical barriers, which offers a high level of security from hacking. The team will develop a Li-Fi prototype system that transmits image data (eg, a medical image) and present it to a computer platform. Minimum resolution of the transmitted image will be specified.

Previous Project (2017-2018): LiDAR in Harsh Weather Conditions

LIDAR has been demonstrated for it's powerful capability in generating high resolution maps for autonomous cars and airborne surveying. Due to the nature of the signal, LIDAR encounters particular difficulty in harsh weather conditions that scatter the signal. Autonomous cars are projected to present a large market for LIDAR, and unlike surveying, the atmospheric conditions for operation cannot be selected flexibly. The aim of this project is to develop a full waveform LIDAR to increase both range and resolution in common harsh weather conditions, such as fog, rain, and snow. This presents a unique opportunity to use LIDAR continuously and reliably. The team will develop a LIDAR alongside novel algorithms for signal processing to extract relevant information and present it to the platform user.

Previous Project (2014-2015): Tricresyl Phosphate (TCP) and CO2 gas sensor

The objective of the project is to design and build a prototype photonic gas sensor for the detection of tricresyl phosphate (TCP) and carbon dioxide (CO2) for use by commercial and small scale aircraft crew. The wearable device will allow for the monitoring of safe levels of both gases in the cabin air. The sensor will be equipped with a Bluetooth transceiver to communicate between the sensor and a central alarm system.

Previous Project (2013-2014): Solar Powered Autonomous Blind System

The objective of this project is to construct an autonomous, off-the-grid blind system that is powered using solar cells. Like traditional blinds, this system would reduce sunlight within a windowed space. This fully automated and self-sustaining system would have the ability to be configured to desired user specifications. Ideally, the blinds would be of a modular design, maintenance free and easy to install.

Previous Project (2012-2013): Multi-touch screen technology

A multi-touch screen is a display which can detect the presence and location of a touch or contact to a display area by a finger or fingers. This technology was first demonstrated in the early 1980s, and has been becoming commercially available. The main types of such technology include: resistive, capacitive, optical, dispersive signal, and frustrated internal refraction (FTIR). This project will explore the touchscreen technology based on light-matter interaction, and the student team will built a functioning multi-touch screen.

Previous Project (2011-2012): Silicon-based solar cells:

This project involves the design, fabrication and testing of silicon based solar cells. Students will

  • use design tools for simulations
  • learn the fabrication processes for semiconductor devices
  • participate in the fabrication runs
  • measure the fabricated solar cell devices
