    • Combined Electrostatic/Electromagnetic MEMS Actuators 

      Alneamy, Ayman (University of Waterloo, 2016-08-10)
      In this work, one and two degrees of freedom (DOF) lumped mass models of Micro- Electro-Mechanical System (MEMS) actuators are introduced, investigated, and compared to experimental results. A one degree of freedom system ...
    • Design and Development of a Training System for Manual Handling Tasks in Masonry 

      McFarland, Tasha (University of Waterloo, 2021-09-24)
      The construction industry is one of the industries with the highest rates of musculoskeletal disorders (MSDs). Masons are particularly susceptible to overexertion and back injuries due to the physical demands of their ...
    • Electrostatic MEMS Bifurcation Sensors 

      ALGHAMDI, MAJED (University of Waterloo, 2018-08-24)
      We report experimental evidence of a new instability in electrostatic sensors, dubbed quasi-static pull-in, in two types of micro-sensors operating in ambient air. We find that the underlying mechanism and features of this ...
    • Electrostatic Micro-Tweezers 

      Alneamy, Ayman (University of Waterloo, 2020-06-25)
      This dissertation presents a novel electrostatic micro-tweezers designed to manipulate particles with diameters in the range of 5-14 μm. The tweezers consist of two grip-arms mounted to an electrostatically actuated initially ...
    • Fabrication, Testing and Characterization of MEMS Gyroscope 

      Almikhlafi, Ridha (University of Waterloo, 2017-05-16)
      This thesis presents the design, fabrication and characterization of two Micro-Electro-Mechanical Systems (MEMS) vibratory gyroscopes fabricated using the Silicon-On-Insulator-Multi-User-MEMS Process (SOIMUMPs) and Polysilicon ...
    • Fast Stress Detection via ECG 

      Malinovic, Aleksandar (University of Waterloo, 2019-05-23)
      Nowadays stress has become a regular part of life. Stress is difficult to measure because there has been no definition of stress that everyone accepts. Furthermore, if we do not get a handle on our stress and it becomes ...
    • Graphene Nanoparticle-Polymer Composite Fabricated by Pulsed Laser Ablation in Liquid 

      ALAMRI, MERVAT (University of Waterloo, 2016-06-09)
      Graphene is an attractive alternative material for diverse applications in electronic devices, fuel cells, biomedical sensors, energy storage, and super-capacitors due to its exceptional thermal, electrical, optical and ...
    • Interactions of Magnetic Pendulums 

      Saeidi Hosseini, Razieh Sadat (University of Waterloo, 2019-09-03)
      In recent years, coupled magnetic oscillators have received remarkable attention due to their application in vibration energy harvesting techniques and also its promising ability to help researchers to have a better ...
    • Tunable Permittivity Sensors 

      Ahmed, Alaaeldin (University of Waterloo, 2021-09-02)
      This thesis presents a novel electric permittivity sensor based on Bleustein- Gulyaev (BG) waves; waves that propagate along the surface of shear-poled piezoelectric materials. BG waves couple electromagnetic and acoustic ...
    • Use of Kinematics to Minimize Construction Workers' Risk of Musculoskeletal Injury 

      Alwasel, Abdullatif (University of Waterloo, 2017-03-29)
      Construction work requires more repetitive and highly physical effort than, for example, office work. Despite technological advancements in construction, the human factor is still an essential part of the industry. Hence, ...
