Development of compact fluorescent spectrometers and field deployable optical solids content monitoring devices
DownloadSpring 2015
Two techniques were used to develop industrial and environmental sensing devices: fluorescence spectrometry and light scatter. The focus of the thesis is to develop real-time, portable and economical sensors using these techniques for environmental detection and management of tailings slurries. A...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...

Development of Microfluidic Chips and a Customised Flow Control System for use in a Label-Free Cytometer
DownloadFall 2013
Conventional cytometry uses fluorescently labelled cells that are laborious and costly to prepare. Using a label-free technique, individual cells can be differentiated by light scattering patterns, a result of different physical attributes. This thesis describes the development of a microfluidic...

Optimization of Electrical Interface for Vibration-based Energy Harvesters for Low Power Applications
DownloadSpring 2020
Badr, Ahmed Osman Abdel-Latif Ahmed
Piezoelectric Energy Harvesters (PEHs) can be used to supply power to small electronic devices as the Wireless Sensor Nodes (WSNs). However, the harvested energy from the harvesters are usually little and needs to be stored into storage elements. A high-efficiency electrical interface with...
