Energy harvesting is an important developing field in Microelectromechanical Systems (MEMS) research. In this thesis, a fixed-fixed folded spring-based harvester is presented as an alternative mechanical element for beam-based piezoelectric harvesters to reduce its natural frequency for low...
A Stochastic Finite Element Analysis Framework for the Multiple Physical Modeling of Filler Modified PolymersDownload
Polymers have various attractive properties (e.g., low volume mass density, low cost and excellent degradation resistance), and hence, they have become essential for a wide range of applications (e.g., aerospace, oil and gas and renewable energy industries). However, due to their limited...
Quantification of the loads applied in biomedical applications has the potential to increase patient safety during surgical procedures and to improve the knowledge of the mechanical behavior of biological tissues. To capture the complexity of loads in biological systems, the acquisition of 3D...
Innovative products based on micro and nanotechnologies (MNT) have made rapid improvements in terms of functionality, cost and performance. Several developments based on these technologies have already benefited society greatly. However, many applications and devices based on these systems are...
An Investigation of Using n-Si Piezoresistive Behavior to Develop a Three-Dimensional Stress Sensing RosetteDownload
This work involves the design, microfabrication, calibration, and testing of a new silicon-based piezoresistive rosette capable of extracting the three-dimensional (3D) stresses in the silicon upon deformation. A new 10-element piezoresistive rosette was devised to extract all stress components...
Many applications of wireless sensor networks (WSNs) require the sensor nodes of a network to belong to different priority classes where the nodes of a higher priority class enjoy higher data rates than nodes of a lower priority class. Practical design of such networks, however, faces challenges...
Development of a MEMS 3D Stress Sensor Using Strain Engineering for Out of Plane Stress ApplicationsDownload
This work aims to enhance the performance of a MEMS-based 3D piezoresistive sensor, which has the capability of extracting the six temperature-compensated stress components. That sensor is made of an n-type piezoresistive element that has low pressure/out-of-plane piezoresistive (PR) coefficient,...
Fabrication, modeling and experimental study of bending deformation of micro-ferrogel fibers in a non-uniform magnetic fieldDownload
Hydrogel smart polymers have achieved a great attention in the research area of drug delivery, MEMS/NEMS, microfluidics and sensor design because of their responsiveness to various environmental stimuli- pH, temperature, light, electric field, enzyme etc. This thesis presents the modeling,...
Numerical Characterization of Ultrasound Elastography for the Early Detection of Deep Tissue InjuriesDownload
Deep tissue injuries - casually termed "bedsores" or "pressure ulcers" - are a type of wound often suffered as secondary injuries in persons with reduced mobility such as those with spinal cord injuries, the elderly, and people with multiple sclerosis. Deep tissue injuries form when excess...
Optimization of Electrical Interface for Vibration-based Energy Harvesters for Low Power ApplicationsDownload
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...
