Title of the Talk: Can Wearables Predict Health Risks Like COVID-19?
Covid19 as it has wreaked havoc with about 100 Million infected worldwide, and more than 2 million deaths as of Jan 2021. And with no reliable cure available yet, early detection and treatment is important to reduce the loss of lives and cost of healthcare. Having consulted with Doctors and Pulmonologists, we understood this was possible by monitoring specific symptoms of respiratory diseases. We know that most of the patients will have typical patterns, including Fever, Cough, HR and then it impacts lungs so Sp02. We researched and filed provisional patents in India and USA for the solution’ a’ware’
a’ware helps to assess risk of Respiratory diseases. This is done using proprietary algorithms built on vitals data including Sp02, HR, Body Temperature and Cough. The solution includes an App and a wearable device that has multiple sensors to gather data.
Initial algorithms are ready and Prospective Observational Studies are underway in Baroda to gather and validate algorithms for risk prediction. More trials and tests are planned before the product will be released for production.

Title of the Talk: Discovering Templates of Engineering Design Hidden in Nature’s Transducers
Nature uses a plethora of micro and nano-scale sensors in its creations. While many of such sensors and actuators have been identified and studied for their functions in animals and insects, we are only beginning to discover the underlying design templates that Nature uses and creates multiple variants of the design with parameter tweaking. Understanding such design templates is essential as they often contain natural scaling of underlying transduction principles and their implementation with physical designs. The modern tools of imaging and characterization are making the discovery of these design templates possible as we are now able to construct the whole system from the information on its pieces from biological studies and piece-together simulations that tell us the whole story. We have been studying the bioacoustics of crickets in order to understand transducer design for efficient sound amplification as well as directional sound detection. We have been also studying insect halteres as gyroscopes to see how such a simple design lends itself to 3-axis rate of rotation sensing. This talk contains some details of these studies that are targeted at discovering the underlying engineering design and a more generic design template.

Title of the Talk: Wearable Magnetic Skins and Sensors
Magnetic sensors are one of the most pervasive sensors in industry and consumer devices. They have a very long history starting with the compass more than 2000 years ago. Many different magnetic sensors have been developed, exploiting various physical principles, to obtain optimized performance for specific applications with respect to sensitivity, power consumption, size, field range or resolution. In the era of ubiquitous sensing, wearable devices and smart things, the unique features of magnetic sensing systems put them at the forefront of novel applications and new features.
This presentation provides insights into latest developments on flexible magnetic skins and sensors, which feature high performance, biocompatibility and conformability. Such devices are employed in biomedical instruments, marine monitoring, or machine-user interfaces, enhancing functionalities and capabilities. Flexible and wearable magnetic sensor systems can extend our senses, provide contactless control or steering and add intriguing new functionalities to our natural capabilities. Examples are flexible magnetic tunnel junction sensors, which are employed for 3-axes orientation monitoring on biomedical instruments. On the other end of the spectrum are printed graphene Hall effect sensors with less sensitivity but high temperature and corrosion resistance. Magnetic composites made of polymers with magnetic materials as fillers combine mechanical flexibility with magnetic functionality. Such materials have been integrated with magnetic sensors to form bioinspired artificial cilia sensors, resulting in low-power tactile sensors with multifunctional capabilities as artificial skins, for flow sensing or brail reading. Ultra-flexible magnetic skins can be worn like tattoos or camouflaged with the color of the skin tone and enable wireless operations, ranging from tracking of eye movements to hands-off machine control.
Modern fabrication processes combined with the advantages of magnetic sensor systems are a strong combination, which can lead to a myriad of new sensor solutions and benefit smart things, robotics, medical devices and much more.

Title of the Talk: Tactile Skin in Robotics and Medical Applications
The miniaturization led advances in microelectronics over 50 years have revolutionized our lives through fast computing and communication. Recent advances in the field are propelled by applications such as robotics, wearable systems, surgical instruments and health monitoring etc., which require electronics to conform to 3D surfaces. This calls for new methods to realize sensing, electronics, and energy related components on unconventional substrates such as plastics and paper. This lecture will present various approaches (over different time and dimension scales) for obtaining distributed electronics and sensing components on flexible and conformable substrates, especially in context with tactile or electronic skin (e-skin). These approaches range from distributed off-the-shelf electronics, integrated on flexible printed circuit boards to advanced alternatives such as e-skin by printed nanowires, graphene and ultra-thin chips, etc. The lecture will also discuss the how large area tactile sensing has changed the research paradigm in robotics from hand-based manipulation to using large body contacts to plan and execute movements even in unstructured environments. The technology developed for sensitive flexible (and possibly stretchable) touch sensing based systems could also enable solutions for numerous emerging fields such as internet of things, smart cities and mobile health as well as global issues related to sustainable environment and health and safety.

Title of the Talk: Self-Powered Wearable Sensors for Health and Environmental Monitoring
Health care spending continues to rise globally and the costs in U.S. now exceed any other industrialized country. Since chronic diseases makeup majority of the health care costs, a disruptive solution to address the health care challenge is to empower users and providers with technologies that provide personal health status and inform patients and doctors with better choices while also enabling rapid and effective treatment. The hassle-free and battery-free features of wearable sensors devices can not only increase adoption and compliance but also enable long-term and continuous monitoring of many key health and environmental parameters. As an example, continuous monitoring of data can provide doctors with trends in physiological data leading up to a traumatic event, making treatment and medication regimes significantly more rapid and effective, and providing feedback to doctors on efficacy of prescribed medications and long-term physical response. Recent advances in nanomaterials, nanostructures, and nanodevices have increased efficiency of energy harvesters, lowered energy per computational bit, increased capacitor storage density, and enhanced nanosensor efficiency making autonomous operation realizable. In this talk, I will how these advances are being combined together to build self-powered wearable sensor systems, which can enable long-term sensing and effective management of chronic conditions, sensing of personal exposure to air pollutants and toxins and provide longitudinal studies that can provide new insight into correlation of various health and environmental parameters. Such sensor systems can empower patients and providers to manage wellness instead of managing illness, assist in effective treatment of at-risk elderly, reinforce healthy lifestyles, and provide new tools for long-term environmental exposure health studies. In order to achieve self-powered operation, it is essential to maximize the power generated from the body and minimize the power consumed by sensors, computation, communication and power management to achieve the self-powered operation. Recent advances in nanomaterials, nanostructures, and nanodevices have increased efficiency of energy harvesters, lowered energy per computational bit, increased capacitor storage density, and enhanced nanosensor efficiency making a self-powered system finally realizable. To address these needs effectively, the ASSIST Center has focused on engineered systems-level approach where the system levels needs drive all the research. I will discuss the challenges in technology development, including energy harvesting, ultra low power radios and durability, needed to realize these sensor systems and explore the role that data will play in making these systems effective for both the patient and the provider.
