A Fully 3D Printed Waveguide and its Application as Microfluidically Controlled Waveguide Switch
DownloadFall 2016
Hollow rectangular waveguides are employed extensively in microwave and millimeter wave devices owing to their relatively high power handling capabilities and low losses, particularly at higher frequencies, compared to transmission lines. However, the fabrication of such metal waveguides suffer...

A study on the effect of print parameters on mechanical properties of parts manufactured using additive manufacturing
DownloadFall 2017
This thesis presents an investigation on material-process interaction of vat-photopolymerization processes. The effect of different printing factors on tensile properties is studied. Two vat-photopolymerization processes are considered: Digital Light Processing (DLP) and Stereolithography (SLA)....

Additive Manufacturing and Other Techniques for Fabrication of Foams and Electrically Conductive Polymer Composites
DownloadSpring 2023
In this thesis, two aspects of advanced uses for additive manufacturing and microfabrication are investigated: stretchable electronics and polymer foams. These topics were initially part of an extended project effort to develop new capabilities in deformable, high-frequency antennas and the...

High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

Development and Usability Testing of a Custom Positioning Surgical Guide for Soft Tissue Breast Reconstruction
DownloadSpring 2019
Breast cancer is the most common cancer in women with more than two thousand new cases diagnosed every year in Alberta. Women endure both physical and psychological hardship from the disease and treatment. Surgical treatment often includes a mastectomy that removes the entire breast. Breast...

Development of a Multi-material Extruder System to 3D Print Hard Thermoplastics, Soft Elastomers and Liquid Metals
DownloadSpring 2019
Functional sensors often consist of rigid parts, soft rubber-like parts, and mechanically tunable electronic components. As part of a larger project to 3D print tunable antennas, it was tasked to develop a printer that could directly produce 3D stretchable electronics with soft and hard...

Ultrasound imaging has great potential in intraoral diagnosis, due to its portability, low cost, and low safety risks. A couplant is normally placed between transducers and tissues for better ultrasound image quality. If applied intraorally, the couplants should possess good stability in water,...
