1. Integration of graphene into MEMS and NEMS for sensing applications
Abstract : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. READ MORE

4. How does the technical status of medical ultrasound equipment affect image quality? Studies based on human observer experiments and a novel method for automatic detection of defective transducers
Abstract : Ultrasound as an imaging modality has a fundamental role in modern healthcare. The equipment, especially transducers, is fragile and handled daily, and transducers are known to sometimes become defective. The overall aim of this thesis was to evaluate how the technical status of the equipment affects clinical image quality. READ MORE
