Pressure and proximity sensors are widely used in the healthcare and robotics industries. Among other applications, they are used for patient monitoring and robotic surgery, playing an integral role in improving health and safety. Currently, there is an increasing demand for highly specialized sensors within these industries, but the path of designing such sensors can be very circular, requiring multiple redesigns. To better address this challenge, the process must be linearized by enabling more targeted sensor design. To achieve targeted design of sensors for specialized applications, there are five major objectives: (1) better understanding of current sensor technologies, (2) more reliable and reproducible sensor fabrication methods, (3) simple models to predict sensor performance, (4) design rules based on computational and experimental results to inform targeted sensor design, and (5) proven efficacy of the targeted design for specific applications. This dissertation goes through this process specifically for capacitive pressure and proximity sensors. Micro-engineered pressure sensors are of particular interest because of their high sensitivity, fast response, and low limits of detection. The micro-engineering techniques include micropatterned structures, porous layers, multilayered packed structures, and combined approaches, and are compared in terms of ease of fabrication, active layer uniformity, shape and size versatility and tunability, and scalability. Understanding the current sensor technologies, advantages of different sensor types, and fabrication methods led to a focus on capacitive pressure sensors with micropatterned structures. The fabrication method for capacitive pressure sensors was improved for consistency and reliability by introducing a lamination layer to anchor the micropatterned structures--pyramids in this case--to the second electrode. A series of equations modeling the dielectric layer as both a spring and electrical circuit was developed to predict sensor response and was confirmed experimentally. This model was then used to predict how a variety of design parameters impacted the sensitivity and initial capacitance of the sensor. Further, the model was expanded to include alternative microstructure geometries and more performance parameters, enabling a more extensive comparison of microstructure design. Once the dielectric layer of capacitive pressure sensors was better understood, an analysis of the effects of electrode design was investigated, specifically for fringe-field capacitive sensors capable of both pressure and proximity sensing. Four novel electrode designs were compared to a traditional parallel plate design. All fringe-field designs had proximity sensing capabilities, distinguish between pressure and proximity regimes, and distinguish between conductive and insulating materials, however only one could recapitulate most of the pressure sensing capabilities of the parallel plate capacitive sensor. Finally, the newly obtained sensor performance trends were applied to targetedly design a sensor for early detection and prevention of diseases after surgical vascular bypass or plaque removal. This sensor was effective in vitro, in vivo, and in a human cadaver without the need to redesign, thus demonstrating the efficacy of using the design guidelines developed for linear, targeted sensor design.

Emerging wide bandgap (WBG) semiconductors hold the potential to advance the global industry in the same way that, more than 50 years ago, the invention of the silicon (Si) chip enabled the modern computer era. SiC- and GaN-based devices are starting to become more commercially available. Smaller, faster, and more efficient than their counterpart Si-based components, these WBG devices also offer greater expected reliability in tougher operating conditions. Furthermore, in this frame, a new class of microelectronic-grade semiconducting materials that have an even larger bandgap than the previously established wide bandgap semiconductors, such as GaN and SiC, have been created, and are thus referred to as “ultra-wide bandgap” materials. These materials, which include AlGaN, AlN, diamond, Ga2O3, and BN, offer theoretically superior properties, including a higher critical breakdown field, higher temperature operation, and potentially higher radiation tolerance. These attributes, in turn, make it possible to use revolutionary new devices for extreme environments, such as high-efficiency power transistors, because of the improved Baliga figure of merit, ultra-high voltage pulsed power switches, high-efficiency UV-LEDs, and electronics. This Special Issue aims to collect high quality research papers, short communications, and review articles that focus on wide bandgap device design, fabrication, and advanced characterization. The Special Issue will also publish selected papers from the 43rd Workshop on Compound Semiconductor Devices and Integrated Circuits, held in France (WOCSDICE 2019), which brings together scientists and engineers working in the area of III–V, and other compound semiconductor devices and integrated circuits. In particular, the following topics are addressed: – GaN- and SiC-based devices for power and optoelectronic applications – Ga2O3 substrate development, and Ga2O3 thin film growth, doping, and devices – AlN-based emerging material and devices – BN epitaxial growth, characterization, and devices

The Internet-of-Things (IoT) has emerged as a powerful and promising technology, and though it has significant technological, social, and economic impacts, it also poses new security and privacy challenges. Compared with the traditional internet, the IoT has various embedded devices, mobile devices, a server, and the cloud, with different capabilities to support multiple services. The pervasiveness of these devices represents a huge attack surface and, since the IoT connects cyberspace to physical space, known as a cyber-physical system, IoT attacks not only have an impact on information systems, but also affect physical infrastructure, the environment, and even human security. The purpose of this book is to help achieve a better integration between the work of researchers and practitioners in a single medium for capturing state-of-the-art IoT solutions in healthcare applications, and to address how to improve the proficiency of wireless sensor networks (WSNs) in healthcare. It explores possible automated solutions in everyday life, including the structures of healthcare systems built to handle large amounts of data, thereby improving clinical decisions. The 14 separate chapters address various aspects of the IoT system, such as design challenges, theory, various protocols, implementation issues, as well as several case studies. Smart Healthcare System Design covers the introduction, development, and applications of smart healthcare models that represent the current state-of-the-art of various domains. The primary focus is on theory, algorithms, and their implementation targeted at real-world problems. It will deal with different applications to give the practitioner a flavor of how IoT architectures are designed and introduced into various situations.
