Design and Testing of a GNSS Reflectometry CubeSat Payload for Monitoring Climate Change
(University of Waterloo, 2017-09-27)This thesis presents an alternative method for using reflected global navigation satellite systems (GNSS) signals as a remote sensing technology. The method aims to reduce the costs required so that the technology can be ... -
Design, Fabrication, and Testing of a Dielectric Elastomer based Ambulatory Active Compression Device
(University of Waterloo, 2016-09-28)Various vascular disorders such as deep vein thrombosis and edema have been associated with the pooling of venous blood in the lower limbs due to extended periods of immobility. Prophylaxis against peripheral vascular ... -
Design, Modelling, and Fabrication of a Low Frequency Piezoelectromagnetic Energy Harvester
(University of Waterloo, 2017-08-31)The growing demand for electricity has put enormous pressure on the current power grid infrastructure and has caused several major blackouts over the past few decades. As a result, there has been a shift towards a modernized ... -
Dynamic effects of harnessing cables on distributed parameter systems for space applications: Analytical modeling and experimental validation
(University of Waterloo, 2020-12-02)Power and data signal cables constitute a major component of lightweight spacecraft and satellite structures. These cables can account for up to as high as 30% of the structural mass and hence significantly impact the ... -
Low-Frequency Piezoelectric Energy Harvester with Novel 3D Folded Zigzag Design and High Power Density
(University of Waterloo, 2018-07-09)Cantilevers have been widely used for vibration energy harvesting applications using piezoelectric materials due to their simple geometries, frequency tune-ability, and closed form analytical solution. Recent studies have ... -
Wearable Tactile Pressure Sensing for Compression Garments and Control of Active Compression Devices
(University of Waterloo, 2016-01-22)Compression garments on the lower limbs have been used for the treatment of venous deficiencies for centuries. More recently, healthy athletes have used similar garments for an edge in performance and improved recovery ...
