Design, Production and Characterisation of an LPCVD-Based Poly-Silicon Carbide Pressure Sensor for Extreme Environments

Sensors are extremely valuable to this world. Without sensors, we would not be able to live as we do in this data-driven environment. Therefore, finding new ways to measure the matter around us is a continuous process. In this work, an addition to the new sensors is attempted, using materials that can withstand the most extreme circumstances....

Testing of Interconnect and Contact Defects in STT-MRAMs

Spin-transfer-torque magnetic random access memory (STT-MRAM) is regarded as one of the most promising non-volatile memory (NVM) technologies, which has the potential to replace the traditional memories in the modern memory hierarchy. Due to some advantages such as non-volatility, fast access speed, low leakage power and high density, more and...

Design of moisture vapor pressure sensor for popcorn failure analysis in molding compound

Moisture absorbed by the hygroscopic polymers like molding compound and die-attach vaporizes during reflow lead to a high vapor pressure inside the electrical components lead to failure in the electrical device, named as popcorn failure. Popcorn failure in plastic encapsulated microcircuits has been a critical issue for electronic device...

Inertial Measurement Unit-based post-surgery knee rehabilitation

Every year, nearly five million people undergo knee, making it one of the most common orthopaedic procedures. Sport-related injuries and age-related diseases are the major causes that lead to a knee operation. To recover mobility, stability and muscle strength, the person must go through a post-surgical rehabilitation program.<br/>The price of...

Multifunctional UV-C LED Virus Inactivation Experimental Platform

Since the outbreak of SARS-COV-2, various virus inactivation techniques have been applied to suppress the spread of virus. Ultraviolet exposure inactivation is an efficient approach to inactivate virus, within UV band, UV-C with comparatively higher energy. UV-C has been proved to inactivate viruses efficiently, while to figure out efficient...

Pre-Silicon Power Leakage Assessment Framework using Generative Adversarial Networks

As of 2021, the world economic forum deems cyber-security failures as one of the most potent threats to the world. According to a McAfee report, the cost of cybercrimes in 2020 reached nearly 1 trillion US dollars, which was around 50 percent more than what it was in 2018. Exacerbating the already mammoth financial implication of such a failure...

Towards All-Polymeric Cochlear Implant Micro-Electrode Arrays

Cochlear implants (CIs) are the most effective solution to treat severe-to-profound hearing loss. These medical devices mimic and replace the function of the damaged structures of the cochlea. To this date, more than 700,000 individuals worldwide have benefited from CIs. However, state-of-the-art CIs do not provide a natural and high-quality...

A combined time-gain compensation low-noise amplifier for ultrasound imaging applications

This work presents a type of low noise amplifiers (LNA) that are used for ultrasound imaging systems. To account for the attenuating nature of ultrasound echo signals, a so-called time gain compensation (TGC) circuit is required. By increasing the gain over time, the output dynamic range is decreased, while the switching artifacts are suppressed...

Design of a novel multi-modal stimulation device for the treatment of tinnitus

Approximately 15-20% of theworld population is aected by tinnitus, a hearing condition associated with phantomsound perception. A large number of suerers experience a severe level of tinnitus and they are not ableto conduct a normal life because they develop insomnia, depression, and distress.Extensive research has been made to study its...

Computational modeling of hepatic blood flow in Fontan circulations: The influence of respiration

Background: The Fontan procedure is the last of three stages of congenital heart surgery to treat children born with a single ventricle heart defect. In these patients, a balanced hepatic blood flow distribution (HFD) towards both lungs is important, since a lack of “hepatic factor” has been associated with the formation of pulmonary...

Establishing the capacity of the muscles around the elbow joint to compensate for the external valgus moment during a fastball pitch: An electromyographic study

Baseball pitching is a movement wherein an external valgus moment around the elbow joint regularly causes an ulnar collateral ligament (UCL) injury. A proven relationship between the muscle activation around the elbow joint and its capacity to compensate for the external valgus moment during a baseball pitch allows predicting the likelihood of a...

Real-time monitoring of sweat of Cystic Fibrosis patients

This research provide a proof of principle to use a sweat sensor system for real-time monitoring of medicine effectiveness in Cystic Fibrosis (CF) patients. CF is an autosomal recessive genetic disorder affecting mostly the respiratory, digestive and perspiration system. Patients with CF have dysfunctional chloride channels in their cells, due...

Microstructure for thermal impedance spectroscopy for biofuel composition measurement

Biofuel sensors for measuring the ethanol and gasoline concentrations in bio-ethanol blends, have been studied world-wide and currently used in engine management in Flex-Fuel cars fabricated by amongst others, Ford Motor Company. However, water that results from ethanol sugar cane is inevitable present in the ethanol blend and requires a sensor...

Smart sensors and communication using IoT in supermarkets: Shelf monitor system

This thesis tries to find a solution for the problem of managing and monitoring the banana shelf in a supermarket using IoT.<br/>The research focuses on using a wireless sensor that detects some features of the banana shelf while being non-intrusive.<br/>The three main features that are examined of the shelf are the quality and quantity of the...

Smart sensors and communication using Internet of Things in supermarkets: Sensor to Server communication

During 9 weeks of investigation multiple solutions for implementing a communication module in a supermarket have been explored. These results led to three options which have been further researched. Bluetooth Low Energy (BLE), 433 MHz and ZigBee have been selected as the best communication protocols<br/>for sensor to gateway communication. Chips...
