    Abstract

    63% of the world's population is connected via the internet as of 2022. What about the remaining 37% which is about 3 billion people!? Why are they not connected yet? The traditional commercial viable approaches either lack capacity or lack reach. Newer technological approaches are needed to create economically sustainable ways to connect all. Also, it is no longer that only people need connectivity but with a plethora of intelligent devices coming into existence machines requiring connectivity are also growing in an exponential way. 5G puts the step in the right direction towards this gap in connectivity but is far from completely addressing it. At Astrome, we have developed and are developing different products and solutions to address the diverse market needs towards bridging this gap. This talk will elaborate the gap and mechanisms to address them and provide a view of the journey at Astrome in this direction.

    Abstract

    NASA’s Jet Propulsion Laboratory, which completed eighty years of its existence in 2016, builds spacecraft and instruments for NASA missions. Exploring the universe and our own planet Earth from the space has been the mission of NASA. Robotics missions such as Voyager, which continues to go beyond our solar system, missions to Mars and other planets, exploring the stars and galaxies for astrophysics missions, exploring and answering the question, “are we alone in this universe?” has been the driving force for NASA exploration since its inception. Fundamental science questions drive the selection of NASA missions. We develop new technologies and innovative instruments to make measurements that can answer these science questions. In this presentation, we will present an overview of the state-of-the-art radar, spectrometers, radiometers, and other instruments that we are currently developing and layout the details of the science questions they will try to answer. Rapid progress in multiple fronts, such as commercial software for component and device modeling, low-loss circuits and interconnect technologies, cell phone technologies, and submicron scale lithographic techniques are making it possible for us to design and develop smart, low-power yet very powerful instruments that can even fit in a SmallSat or CubeSat. We will also discuss the challenges of the future generation instruments in addressing the needs for critical scientific applications. The research described herein was carried out at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, USA, under contract with National Aeronautics and Space Administration.

    Abstract

    Microwaves are electromagnetic radiation in the frequency range of 300MHz to 300GHz corresponding to wavelengths of 1m down to 1 mm. They can be used in many applications such as - communication, imaging visually obscured objects, wifi and cooking. In this presentation, we will start with a kitchen oven with a magnetron source at ~ 2.4 GHz and demonstrate how electronics can bel upset and even damaged. We will then move on to high-power (100’s MW to GW) microwave sources and illustrate how they can be weaponized against electronic systems. Individual drones and swarms of drones are already being used in warfare with data links in microwave frequencies to controllers on ground. Some illustrative examples of sources and antennas will also be presented.

    Abstract

    Diagnosing and early detection of chronic diseases in remote settings is always a challenge without access to costly, well-equipped clinical laboratories and trained medical personnel. Consequently, developing diagnostics for chronic conditions that are cost effective and can be easily implemented, remains an important goal in global health. To achieve this goal, one promising approach is to detect disease biomarkers from accessible body fluids with point-ofcare (POC) biosensors that are inexpensive, minimally invasive and do not require trained medical personnel. Point-of-care biosensor systems can potentially improve patient care through real-time and remote health monitoring. Apart from infectious conditions, global health challenges have shifted towards noncommunicable chronic diseases (NCDs) such as diabetes mellitus, heart disease, chronic kidney disease, liver disease and cancer, which constitute an increasing majority of global mortality. PathShodh Healthcare is driven by a social mission to achieve the goal of affordable, accurate and cost-effective diagnostics, based on the patented bio-sensing technologies. Here, I will discuss the PathShodh journey to develop the novel products for point of care diagnostics of public health conditions

    Abstract

    Optical fluorescence is fast emerging as a possible substitute for nuclear medicine isotopes in functional biomedical imaging. We will give a brief overview of fluorescence based optical and photoacoustic tomography. Static settings correspond to the imaged quantity of interest such as the absorption/scattering coefficient of a pathological tissue, not varying with time. In dynamic settings, such as those found in pharmacokinetic imaging, the time varying concentrations of injected fluorophores are spatio-temporally imaged, along with their underlying (pharmacokinetic) rates of leakage with respect to the tissue under investigation.
    We will introduce (a) an enhanced model for directional sources and scattering with a delta-Eddington based simplified spherical harmonics approximation, in fluorescence optical tomography, and, (b) a fluorescence photoacoustic tomographic framework for the dynamic pharmacokinetic tomography problem.

    Abstract

    While the computing demands of Information Technology are ever increasing, the capabilities of electronics have hit fundamental walls due to energy and dimensional unscalability. In this talk, I will demonstrate the quantum mechanical transistor, which beats the fundamental energy limitations. This device is the world's thinnest channel (6 atoms thick) sub-thermal tunnel-transistor. Thus, it has the potential to allow dimensional scalability to beyond Silicon scaling era and thereby to address the long-standing issue of simultaneous dimensional and power scalability. Going beyond electronic computation, I will discuss about the biological computer: the brain, which can be thought of as an ultimate example of low power computational system. I will introduce the technology, which reveals for the first time, a nanoscale trans-synaptic architecture in brain and the way mother nature has engineered biomolecular organization in the brain to optimize its computing efficiency. This technology can also be used to decipher intriguing biomolecular nanoarchitectures related to neurological diseases, otherwise invisible to existing technologies. I will conclude with our group’s research vision for how extremely powerful technologies can be built by fusing diverse fields and discuss briefly about the research directions of my new lab at MIT.

    Abstract

    Radiative communication using electromagnetic (EM) fields is the state-of-the-art for connecting wearable and implantable devices enabling prime applications in the fields of connected healthcare, electroceuticals, neuroscience, augmented and virtual reality (AR/VR) and human-computer interaction (HCI), forming a subset of the Internet of Things called the Internet of Body (IoB). However, owing to such radiative nature of the traditional wireless communication, EM signals propagate in all directions, inadvertently allowing an eavesdropper to intercept the information. Moreover, since only a fraction of the energy is picked up by the intended device, and the need for high carrier frequency compared to information content, wireless communication tends to suffer from poor energy-efficiency (>nJ/bit). Noting that all IoB devices share a common medium, i.e. the human body, utilizing the conductivity of the human the body allows low-loss transmission, termed as human body communication (HBC) and improves energy-efficiency. Conventional HBC implementations still suffer from significant radiation compromising physical security and efficiency. Our recent work has developed Electro-Quasistatic Human Body Communication (EQS-HBC), a method for localizing signals within the body using low-frequency transmission, thereby making it extremely difficult for a nearby eavesdropper to intercept critical private data, thus producing a covert communication channel, i.e. the human body as a ‘wire’.

    Abstract

    Power technologies are front and center when it comes to developing greener and sustainable products and applications. As electronics proliferates into different aspects of our lives, there is a greater demand for technologies that deliver better and better energy efficiency. Take the example of a standard data centre – these consume approximately 35MW hr energy per day, which is all set to increase between 2x to 8x in the next decade. One cannot ignore the physics of work done is not 100% efficient. With inefficiencies come thermal effects etc. Research to solve this problem is driving innovations in circuits, processes and packaging to save tens of Mega Watts in Server Farms for data centres by continuously improving Power Density & increasing power and thermal efficiency. GaN, thermally enhanced packages, regenerative methods are just a few examples that have created exponential savings. Every percent saved through efficiency and improvements in thermal packaging directly maps to MWH of energy saved per year. Contrasting MW power is the ultra low power (sub nW solutions) yet high precision, smart sensor processors for health care, industrial systems, Smart Electricity Meters etc. pushing the technology towards life-long-no-battery-replacement solutions. Let us take a sneak peek into how do we do this with process, package and IC design and continue to push technology addressing new challenges in this domain.
