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....

Route towards power MOSFET large thin die mechanical robustness: Masters thesis report

Today’s cars are undergoing the greatest transformation the industry has seen. Power MOSFETs play a crucial role in making electronics more energy efficient by driving down switching losses and Rdson using a combination of next-generation trench technology and ultra-thin dies. Power MOSFET dies are becoming larger ( > 5 X 5 mm ) and thinner (...

Design and characterization of an implantable system for shockfree cardiac rhythm control

LED-stimulated Liquid Crystalline Elastomers (LCEs) as Contractile Units for Assisting Cardiac Contraction

Heart Failure (HF) is a disease of high mortality and morbidity with huge impact on health care systems worldwide. HF is a result of decreased contraction of the heart muscle. Current treatments focus on symptoms,and only a minor portion of HF patients is eligible for surgery. Assistance devices for cardiac contractionare currently only...

High aspect ratio surface micro-machining using carbon nanotubes

Silicon-based MEMS technology has been the standard for developing 2D and 3D<br/>micro-structures for many years. There are 2 main classifications of MEMS manufacturing technologies, viz. bulk micro-machining, and surface micro-machining.<br/>These techniques have its own set of drawbacks. Bulk micro-machining affects the structural integrity of...

Board Level Vibration Testing and Qualification for Automotive Application

Revolutionary changes in automotive industry toward fully connected electrical vehicles is changing the world of Board Level Reliability (BLR) Vibration Testing. It is taking BLR Vibration tests beyond board level to board module application level.<br/>In this thesis, it contains the development of a reliability test concept called Board Module...

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...

Smart Personal Protective Equipment: On-Board Power Management

The COVID-19 pandemic caused a shortage of Personal Protective Equipment for Healthcare personnel. This project aims to aid in this shortage by extending the lifetime of the filter material used in a mask. This is done in the form of an SPPE, a Smart Personal Protective Equipment. This face mask has two smart filter heads that are modular and...

Smart Personal Protective Equipment: UVGI

The Smart Personal Protective Equipment (SPPE) is proposed as a result of the COVID-19 pandemic, which has led to shortages of standard face masks. This thesis describes one of the three subsystems of the SPPE, namely the Ultraviolet Germicidal Irradiation (UVGI). The UVGI subsystem provides the SPPE with an in situ disinfection system, in order...

Smart Personal Protective Equipment: Sensing and Control: The future of face masks

The current COVID-19 pandemic shows the necessity of personal protective equipment and face masks. In the project, a filter module with an in-situ ultraviolet-sterilization technique is designed that can serve as a new kind of smart personal protective equipment (SPPE). This technique is not used in wearable devices as of yet. The project thus...
