9:00AM SESSION 1: POWER AND ENERGY STATE-OF-THE-ART AND NEEDS
SESSION CHAIR: Suresh Sitaraman; Regents’ Professor and Morris M. Bryan, Jr. Professor, Georgia Institute of Technology
“IoT Innovation and Solving Long-term Energy Dependencies” AT&T Internet of Things
Abstract The intersection of next-gen IoT centric connected technologies, coupled with innovation based energy harvesting technologies is enabling new IoT based use cases that are economically viable and standalone sustainable for up to 10 years. Learn how this is changing the game in our race to connect everything of value to improve business and personal outcomes.
“AI @ Edge” IBM T.J. Watson Research Center
Abstract Despite the power to process massive volumes of data and derive insightful insights, artificial intelligence applications have one major drawback – the brains are located thousands of miles away. “Edge computing” is a new paradigm in which the resources of a small data center are placed at the edge of the Internet, in close proximity to mobile devices, sensors, and end users, and the emerging Internet of Things. This talk will outline key enabling technologies and use cases for bringing intelligence to the edge.
“Needs and Gaps for Wearable Sensing Technologies to Enable Cancer Patient Monitoring, Remotely” National Cancer Institute (NCI) of the National Institutes of Health (NIH)
Abstract The rapid adoption of wearable and external sensing platforms since 2015, by the consumer health market, have begun to pave the way for similar platforms to act as objective measures for continuous, out of clinic cancer research and patient assessment. The passive, continuously measured data streams generated by current or future physical and chemical/biological sensors will allow direct/indirect measures of disease progression and its symptoms. Increased out of clinic patient and clinician engagement via these tools will allow more precise delivery of healthcare post-diagnosis as well as during remission. Ultimately, these passive sensing platforms of digital biomarkers will afford clinicians 1) more objective metrics of response to therapeutics; 2) control and auto-reporting of symptoms and their fluctuations; 3) monitoring of side-effects / toxicity of experimental or standard of care therapies; and 4) more ecologically valid clinical endpoints, in essence decreasing assessment burden via increased continuity of physiological measurement sampling and patient context, outside of the standard clinical visit. Although, perceived to have much impact in the delivery of healthcare, many hurdles remain to the implementation of an “Internet of Cancer Medical Things.” This talk will look at various efforts across the National Institutes of Health and National Cancer Institute attempting to enable more objective measures for out-of-clinic assessment and understanding disease progression, more precisely in time and context. As well as focus upon needs and gaps in the technologies relative to their validation and perceived power requirements.
“Opportunities in Powering the Digital Transformation of FHE IOT Ecosystems” Jabil
Abstract Digital revolution is upon us and Connected Devices as part of the digital transformation are getting ubiquitous. Integrating both the hardware data collection and analytics layers of the IOT ecosystem across different domains (smart retail, hospitality, health & safety) can help enhance the ROI of the solution. Some examples of such integration are discussed in this presentation to provide a window into the opportunities. While there are several subsystem components the presentation outlines opportunities and challenges for power and energy requirements enabling hardware especially leveraging current and future technologies in flexible hybrid electronics. FHE allows for opportunities where not only are the benefits of functional integration realized but potentially impact on easier manufacturing processes, reduced assembly steps and supply chain simplification is also possible. The emergence of 3d printed electronics for PCB manufacturing is presents unique opportunities for integrating flexible hybrids to realize complex designs.
“DoD Ground Expeditionary Power & Energy Needs” NSWC Carderock Division
Abstract US DoD Ground Forces face unique logistics challenges when operating at the tip-of-the-spear in forward deployed, austere locations. Specifically, fuel and battery resupply is costly and vulnerable to attack. US DoD Ground Forces desire greater operational reach with reduced reliance on resupply. The focus of this talk is to communicate high-level DoD Expeditionary Power and Energy needs in the realms of renewable energy, energy storage, and tactical power generation to reduce or eliminate fuel and battery resupply.

“Leveraging RF Power for Flexible Hybrid Electronics” PARC
Abstract Power provisioning is a critical need for flexible-hybrid electronics (FHE) systems. Flexible thin-film battery technology has improved significantly in recent years. Yet the small form factors required by many FHE applications necessitate limited capacity. With the extremely low power consumption and advanced power management architectures of emerging electronic components, energy harvesting and remote power delivery have become feasible. Electromagnetic radiation in the form of radio-frequency (RF) waves is one means of delivering power to FHE systems. PARC has developed roll-to-roll printable antennas and rectifiers for RF energy harvesting. Current work includes the development of a system for using steered directed RF energy to power peel-and-stick battery-less sensor tags.
“Harvesting Electricity from Various Sources of Waste Heat Through Thermoelectrics” Silniva Corporation
Abstract But for its thermal conductivity silicon is the perfect thermoelectric material (TEMat). Exploiting a breakthrough in decoupling thermal and electrical conductivity in silicon, achieving thermal conductivity less than .2 W/mK, a refractory low coefficient of thermal expansion material (CTE) enables thermal electric generators (TEGs) to harvest waste heat to generate electricity. An example will be harvesting waste heat from the exhaust manifold in autos will be illustrated with economics justified with regard to capital expenditures (CAPEX) operating costs (OPEX) and environmental considerations including the EU penalty of Euro 95 gram/km CO2 over 103 grams/km starting in 2019.

1:30PM SESSION 3: ENERGY STORAGE STRATEGIES
SESSION CHAIR: Enoch Wang, Government
“Flexible, Printable, and High Temperature Lithium Ion Batteries” Air Force Research Laboratory
Abstract Flexible and printable energy storage facilitates innovation in the manufacture of flexible electronics in that it will enable direct integration of a power source into a device during the fabrication process. We have explored two approaches towards next generation flexible energy storage. The first approach utilizes a mechanically robust and flexible current collector based on a nonwoven carbon nanotube mat to create highly stable, bendable and even creasable Li-ion batteries. These batteries showed uncompromised discharge voltage stability under dynamic mechanical strains, such as flexing, bending (600 roll/unroll cycles), and creasing (300 ±180° folds) while maintaining the same electrical performance as traditional, unstrained cells. The second approach utilizes additive manufacturing to enable direct integration of a power source into a device during the fabrication process. To enable such advancement, we demonstrated a universal approach to develop free-standing and flexible electrodes for printable, high-performance Li-ion batteries. This simple approach utilized a well-dispersed and directly castable mixture of active material, carbon nanofibers, and polymer to make printable electrode inks. To complement this component, we demonstrated a dry phase inversion technique representing a step toward controlled, printed porosity in Li-ion battery electrolytes. Our approach utilized a solvent/weak non-solvent system to generate porosity within a polymer matrix and a ceramic Al2O3 filler to control pore size distribution and tortuosity. These electrolytes offered electrochemical performance on par with commercial separators, with better thermal stability and electrolyte wetting. This technology for both electrolyte and electrode inks is an enabling step toward direct integration of flexible power in confined areas or on non-planar device surfaces.
“Flexible Batteries for Next-Generation Internet of Things” Georgia Institute of Technology
Abstract Electrodes for batteries are traditionally prepared by casting a slurry comprising active particles, conductive additives and a binder on metal foil current collectors, followed by drying the slurry and calendaring. While this process has been commercially successful, it suffers from several limitations, including the lack of flexibility and strength. Multifunctional flexible batteries capable of providing energy storage coupled with load bearing ability are attractive for next generation Internet of Things and other applications where robustness, flexibility and reduced mass and volume are important. Since nearly all of the fundamentals and performance metrics of batteries have been traditionally performed by electrochemists, the mechanical properties of battery electrodes of various architectures have often been grossly overlooked. Accordingly, an understanding of how electrochemical and mechanical properties could be coupled in novel design architectures of flexible batteries is severely lacking. Here I will discuss novel synthesis routes, including chemical vapor deposition and solution inviltrations, and structure-property relationships for several flexible battery technologies that offer high energy, high power, lightweight and high strength. Substantial part of the talk will be devoted to synthesis and characterization of flexible Li-ion battery electrodes.
“Solid State Rechargeable Batteries: A Review” Oak Ridge National Laboratory
Abstract Safety concerns associated with the traditional liquid electrolyte-based secondary batteries drive the research towards development of alternative technologies, where toxic and highly flammable solvents are eliminated from the electrolyte composition. Such safety considerations are especially relevant in the case when powering wearable devices by batteries is required. Solid state thin film cells as well as batteries based on polymer electrolytes are suitable to provide the path forward. This talk will overview the recent advances in this area based on the research performed at the Oak Ridge National Laboratory as well as analysis of gaps and limitations. Interplay between mechanical properties and ionic conductivity will be discussed among other topics.
“Flexible Printed Batteries Powering Wearables and Other IoT Applications” Blue Spark Technologies
Abstract The proliferation of electronic devices has always beckoned for more powerful batteries. Enter the Internet of Things (IoT) and the demands of batteries have expanded to include thin, flexible and disposable to power wearables and other flexible electronics that require a thin profile. This talk will focus on thin printed batteries; considerations in their design and manufacturing, and implications of incorporating printed batteries into thin devices. Two applications for flexible printed batteries, one of a wearable medical device and the other, an industrial temperature sensing device for supply chain will be used to highlight the practical aspects of battery manufacture and connecting the battery to the device.
3:30PM SESSION 4: POWER MANAGEMENT AND ULTRA-LOW POWER ELECTRONICS/SENSORS
SESSION CHAIR: Daren Heidgerken; Program Manager, Corporate Engineering and Program Operations; Lockheed Martin
“Beginning the Journey Toward Self-powered Systems on the Right Footing” Analog Devices, Inc.
Abstract This talk will outline the steps and decisions one must make early in the customer journey when seeking to develop autonomous life-cycle systems. Careful consideration should be devoted to these issues before a decision to pursue a self-powered system development can be made – a decision that necessitates a new energy constrained design paradigm and way of approaching the problem to be solved. The talk will start with discussing the different energy supply options available to designers today, their advantages/disadvantages and typical edge conditions that one must take into account and how those map to changes in the end-product user experience. Typical harvesting methods and transducers will also be reviewed in light of engineering considerations that must be made with respect to measuring the available ambient energy, use and appropriate interfacing and incorporating into end-user applications, and proper selection of power management components. Special attention will be devoted to pointing out current and future intersection points with flexible hybrid electronics. This journey will be illustrated by a case study on how to effectively incorporate thermoelectric harvesting into a self-powered edge node while managing the thermal interfacing issues.
“Power Delivery and Management in Flexible Substrates for IoT Applications” Georgia Institute of Technology
Abstract Flexible Hybrid Electronics (FHE) provides for an interesting solution for several IoT applications where the electronics can be made to conform to curved surfaces and be subjected to bending, stretching, folding, twisting, etc. Power delivery in such FHE solutions pose unique challenges since not only does the power need to be harvested, but it also needs to be stored, optimized, managed and delivered in a configuration that may not be conducive to such operations. In this talk we explore power delivery solutions based on wireless power transfer with a focus on architecture, modeling, fabrication, characterization and implementation by identifying challenges and potential solutions, with an end goal of incorporating the knowledge gained into process design kits (PDK) for dissemination to the FHE community.
“Adding Less Power to Deeply Embedded Systems” Texas Instruments Innovation and Development
Abstract Suitable for energy harvesting applications, this presentation details practical embedded processing techniques that dramatically reduce system power consumption from milliamps to micro-amps. Managing and budgeting a highly restricted, often high-impedance, system power source is the fundamental undertone of this presentation. The importance of a of duty-cycle based architecture, power-gating external sensors, utilizing autonomous processing and data conversion, as well as the strict utilization of energy-aware firmware will discussed and quantified. The often hidden impact of system clock frequencies, supply voltage, temperature, stray capacitance and buss loading will also be reviewed. The presentation builds through a series of examples, a complete sensor-processing embedded system including a restricted power source, sensor, data convertor, MCU and user interface. Using the techniques discussed, a working ultra-low power deeply embedded sensor sampling system that uses common and cost effective off-the-shelf components will be demonstrated live as part of this interactive presentation.
