Book excerpt: Today's implantable medical devices rely on bulky batteries for energy supply, requiring invasive implant procedures, which limits their use to only last-resort therapies. New applications of implantable devices are being proposed, such as: peripheral nerve stimulation for treating chronic pain and inflammatory disease, optogenetic stimulation for mapping of neural pathways, and even sensing applications of neural potential, pressure, and temperature monitoring. To realize these new applications, and to achieve widespread use of implantable device therapy, a new energy paradigm must be designed to replace the batteries and allow for extreme implant miniaturization for minimally invasive implant procedures. Extreme implant miniaturization is especially critical for developing sensors for continuous monitoring, due to a higher threshold for implantation. Towards this goal, we propose ultrasound for efficient power transfer to deeply implanted and miniaturized implantable devices, and demonstrate ultrasonic link utility with design of an implantable pressure sensor and optogenetic stimulator. A comprehensive analysis and methodology is presented for designing ultrasonic receivers for efficient powering of miniaturized implantable medical devices. Key ultrasonic receiver efficiencies, resonance characteristics, and the inductive band are defined, and a theoretical model is presented for first-order design insights. Methods are described to accurately characterize the ultrasonic receiver impedance and acoustic-to-electrical aperture efficiency. Ultrasonic receivers are shown to achieve favorable source resistances from kOhm to 100's of kOhm, for matching to typical implant loads, and high aperture efficiencies of 40-90%. An iterative design methodology, using the theoretical model and impedance measurements is demonstrated for an example ultrasonic receiver design. An ultrasonically powered, millimeter-sized implantable device is proposed for future optogenetic peripheral nerve stimulation in large animal models. Through system level analysis, the effective impedance match between the ultrasonic receiver and implant electronics is shown as the dominant component of the power recovery efficiency. We present a numerically solved time-domain impedance match analysis of the non-linear power electronics to derive the optimal ultrasonic receiver impedance, and the design of the ultrasonic receiver is shown to meet this specification. The implantable stimulator is characterized through both electrical and optical measurements, demonstrating high peak optical intensities of 1-15 mW/mm2 with safe levels of ultrasonic power. Finally, a high-precision implantable pressure sensor with ultrasonic power-up and data uplink is presented for applications in continuous pressure monitoring. The fully integrated implant measures 1.7 mm x 2.3 mm x 7.8 mm and includes a custom IC, a pressure transducer, an energy storage capacitor, and an ultrasonic transducer. In order to reduce overall dimensions, unique circuit and system design techniques are presented to enable a single time-multiplexed ultrasonic transducer for both power recovery and data uplink transmission. Implant performance is characterized at significant depths, 12 cm in a tissue phantom, offering a > 13x improvement over the state of the art in the depth/volume figure of merit, while demonstrating a robust ultrasonic data uplink with better than 1e-5 bit error rate. A transient charging analysis is presented to derive the optimal ultrasonic receiver impedance and charging specifications to maximize overall harvesting efficiency. The IC features a front-end with a 10-bit SAR ADC, achieving a pressure full-scale range of 800 mmHg with a pressure resolution of 0.78 mmHg, exceeding the requirements for a wide range of pressure sensing applications, while accounting for various nonidealities. The pressure sampling rate is fully externally controlled, up to 1 ksps, in order to significantly decrease implant energy consumption and to allow for adaptable programming for specific applications. The implantable sensor is packaged in biocompatible materials and wirelessly characterized in a custom-built pressure chamber, and in situ, using sheep tissue.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD dissertation focuses on developing efficient ultrasonic (US) wireless power and data transfer technologies for biomedical implants with millimeter (mm) dimensions. An ultrasonically interrogated (power/data) system with an external US array for beam focusing and steering through US beamforming is proposed to enable gastric electrical-wave mapping for diagnosing and eventually treating gastrointestinal motility disorders. The dissertation is divided into five parts. In the first part, the theory, design, and characterization of a wireless power transfer (WPT) link using mm-sized receivers (Rx) and a phased array (as external transmitter) are discussed. For given constraints imposed by the application and fabrication, such as the load (RL) and focal/powering distance (F), the optimal geometries of a US phased array and Rx transducer, as well as the optimal operation frequency (fc) are found through an iterative design procedure to maximize the power transfer efficiency (PTE). An optimal figure of merit (FoM) related to the link's PTE is proposed to simplify the US array design. In measurements, a fabricated 16-element array driven by 100 V pulses at an optimal frequency generated a US beam with a pressure output of 0.8 MPa and delivered up to 6 mW to a 1 mm3 Rx with a PTE of 0.14%. In the second part of this dissertation, a comprehensive study of wireless power transmission using a 32-element phased array capable of beam focusing and steering up to 50 mm depth and ±60o angle is provided. The performance of the US WPT link using mm-sized US receivers with different geometries and dimensions, the effect of different types of errors in the delay profile of the beamforming system on the delivered power, and the feasibility and efficacy of implant's localization with pulse-delay measurements with limited number of elements are investigated. The WPT link performance is evaluated based on the delivered power (within FDA safety limits) to mm-sized receivers with different geometries and diameters. In the third part of this dissertation, optimal US pulse transmission is demonstrated that could be used for data transmission to/from millimeter-sized biomedical implants in general or the self-image-guided ultrasonic (SIG-US) WPT. In SIG-US WPT, short pulses are transmitted by the implant periodically. The relative delays in the received signal by each external transducer in an array are then used to guide the beamformer for optimal steering of the power beam towards the implant. The effect of number of transmitted pulses on the iv amplitude of the received signal is studied, which is vital for low-power robust transmission. Furthermore, an adaptive application-specific integrated circuit (ASIC) for closed-loop low-power (and robust) US pulse-based data transmission is presented. The number of transmitted US pulses is changed based on the received voltage at the external unit in the closed-loop system to improve robustness and minimize the power consumption of the data transmitter. The ASIC, designed and fabricated in a 0.35[mu]m standard CMOS process, includes power management, controller/pulse driver, and envelope detector units. The fourth part of this dissertation includes ASIC design for low-frequency, low-power, and low-noise amplifiers that will be used to record gastric slow-wave signals. Simulation results and some limited measurement results are provided. The fifth part of this dissertation includes measurement results for a dual-mode ultrasonic- magnetic approach for wireless power transmission and energy harvesting. This dual-mode approach has the potential to solve the problem of power reduction when implant is rotating and to deliver high power within FDA safety limit using two different modalities. The future steps for circuit/system design, development, and testing are outlined. This dissertation represents an important step towards an implantable fully wireless gastric system, interrogated with a dual-mode ultrasonic-magnetic link for wireless power/data transfer, which can have a broad impact in the fields of health monitoring, diagnosis, and therapy.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research work enclosed in this dissertation is to develop high-performance wireless power and data transfer technologies as well as energy harvesting techniques for implantable and wearable medical devices. The first part of the research work focuses on developing wireless power transmission (WPT) to and communication with millimeter (mm)-sized implantable medical devices (IMDs). Ultrasonic and inductive techniques are developed to achieve high power transfer efficiency (PTE) and low-power pulse-based communication. The second part is to implement an ultrasonic wireless link in a real-world application of ultrasonically interrogated distributed system for gastric slow-wave (SW) recording. The third part is to develop a power management integrated circuit (PMIC) for piezoelectric energy harvesting in next generation self-powered wearables. Wireless power and data transmission techniques have been proven to be promising solutions for IMDs considering size, weight and lifetime limitations, such as bioelectronic medicines, biosensors, and neural recording/stimulation systems. Ultrasonic links utilizing piezoelectric transducers have shown advantages over other techniques in miniaturizing the IMDs which can greatly reduce the invasiveness and increase the longevity of the IMDs while maintaining high efficiency, especially for applications requiring deep implantation. Ultrasonic wireless links can be used in many applications. In this dissertation, an ultrasonically interrogated (power/data) distributed system (Gastric Seed) is proposed for large-scale gastric SW recording. Efficient ultrasonic power links and low-power pulse-based data communication are developed. A Gastric Seed chip is developed with emphasis on self-regulated power management and addressable pulse-based data communication. The self-regulated power management can perform rectification, regulation, and over-voltage protection in one step using only one off-chip capacitor which significantly reduces the size of the Gastric Seeds. The addressable pulse-based data communication is proposed and implemented as a proof-of-concept distributed Gastric Seeds. The pulse-based data communication consumes ultra-low power of 440 pJ/bit.Energy harvesting has become more attractive for self-powered wearables that can enable vigilant health monitoring with 24/7 operation. Piezoelectric energy harvesters (PEHs) can be excited by mechanical vibrations to convert mechanical energy into usable electrical power. PEH is in favor because of high power density and scalability. This outlines the need for an efficient energy-harvesting PMIC to extract maximum energy from PEHs that can be used for self-powered wearables.This dissertation summarizes the contributions in research areas of ultrasonic power and data communication links and energy harvesting PMIC for PEHs. The contributions include 1) development of the theory and proposing the design methodology to optimize the PTE of ultrasonic links involving mm-sized receivers (Rx), 2) design, development, and validation of a hybrid inductive-ultrasonic WPT link for powering mm-sized implants utilizing two cascaded co-optimized inductive and ultrasonic links for WPT through media involving air/bone and tissue, 3) proposing the concept of self-image-guided ultrasonic (SIG-US) interrogation in a distributed, addressable peripheral nerve recording system to ensure high delivered power regardless of the implants movements by automatically tracking the location of the implant in real time, 4) development of a mm-sized Gastric Seed chip towards a distributed recording system for acquiring gastric SWs at a large scale, and 5) development of an autonomous multi-input reconfigurable power-management chip for optimal energy harvesting from weak multi-axial human motion using a multi-beam PEH.

This book was released on 2022-02-08 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘On Power: Neurophilosophical Foundations and Policy Implications’ seeks to provide a historical, contemporary and predictive analysis of power. It aims to explain the history of political power in a unique way by approaching the concept of power through the lens of neurophilosophy – the application of neuroscientific principles to practical questions of governance, ethics, political and moral philosophy. In this book, Professor Nayef Al-Rodhan provides an accessible, incisive, and provocative take on the history, nature, and future of power. His insights go beyond conventional wisdom by exploring some of the themes that will become increasingly relevant to analysing power in the decades to come. A central idea of the book is the highly addictive universal nature of power at the neurochemical level, the craving for it, and the intense resistance to giving it up in all walks of life and circumstances. This can be applied directly to thinking about governance, political change, public policy, national and international peace, security, and prosperity. Al-Rodhan formulates an innovative conceptual picture of power by integrating the findings of neuroscience with the broader implications of power in the era of digital connectivity and cognitive and physical enhancement technologies. In doing so, he guides our approach to political power and public policy, influenced by ubiquitous, disruptive, and intrusive technologies. This book will appeal to students and scholars of neuroscience, philosophy, government, business, and international relations. It will also hold particular interest for politicians, public servants, think-tankers, policy-makers, and journalists, as well as senior executives from the corporate, sports, media and entertainment world.

Available in PDF, EPUB and Kindle. Book excerpt: Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.
