Full-Day Workshop: Energy Harvesting is Out of the Lab

April 20 @ 9:00 am - 5:00 pm

Full-Day Workshop: Energy Harvesting is Out of the Lab
Sponsored by the SF Bay Area Chapter, IEEE Power Electronics Society
Co-sponsored by the UC Berkeley IEEE PELS-IAS Student Chapter and IEEE Consumer Electronics Society Silicon Valley Chapter

Abstract:
Did you think powering your applications with free, ambient energy by the utilization of EH solutions was only a dream that is still an academic lab experiment? Perhaps you thought EH cannot produce enough power to be practical for today’s applications. In fact, EH produces enough power across the spectrum, depending on the energy source, operating environment, and application. From nW to GW, there is a complete, production ecosystem of EH constituents (i.e. transducers, controllers/PMICs, energy storage) to enable today’s hottest applications in IoT, wearables, biotech, and even industrial applications.

In addition to the six speaking topics, there will be a functional demo expo to demonstrate a host of technologies is real-world applications of common interest. The objective here is to follow-up the knowledge gained from the workshop lectures with tangible demonstrations of various EH technologies and key applications.

Technical Talk Details

  • Session 1: SOLAR FOR UNMANNED AERIAL VEHICLES, Instructed by Rodney Amen, Alta DevicesSolar power is everywhere, and we are only just learning the capabilities of this technology. We know solar can provide power to remote locations, but now solar is enabling continuous flight in Unmanned Aerial Vehicles (UAV) serving many applications such as communications, monitoring, and dangerous missions. But not all solar is made equal, a thin-film GaAs solar array offers superior performance for UAVs because of its efficiency, size, and weight in a thin form factor.UAV solar electrical integration can be simple or complex depending on the designer’s desirable trade-offs. Examples will be analyzed of different strategies of solar UAV electrical integration. Regardless of the integration method, solar can enable aircraft to fly all day.
  • SESSION 2: SYSTEM DESIGN FOR SELF-POWERED SENSORS, Instructed by Patrick Riehl, Analog DevicesWe are intrigued by the market possibilities of self-powered sensors, which draw all the energy they need from the ambient environment. Achieving this energy balance requires not only a sufficiently powerful energy harvester, but also an energy-efficient signal path and power path. In this presentation we walk through a few detailed examples including a machine-health monitor powered by waste engine heat. We discuss strategies for optimizing the energy efficiency of the signal path without losing critical information, and identify some common causes of wasted energy. We also show how ADI power management products can be used to optimize the energy efficiency of the system. Completing the model with an energy harvester, we discuss the feasibility of achieving perpetual self-powered operation.
  • SESSION 3: INTRODUCTION TO THE ENERGY HARVESTING KIT, Instructed by Hebberly Ahatlan, Wurth MidcomEnergy harvesting has recently become a topic of much discussion with its potential to self-power autonomous devices for wearables, medical devices and for IoT. The technology has already progressed from the laboratory to commercial applications in areas such as wireless, solar, thermal and wind energies. Come learn how to implement solutions using energy harvesting using our kit that includes “ready-to-use” modules. In addition, learn how to select magnetics for your application that will maximize power efficiency.
  • SESSION 4: APPLICATION OF THERMOELECTRIC DEVICES FOR INDUSTRIAL WASTE HEAT RECOVERY, Instructed by John Reifenburg, Alphabet EnergyAlphabet Energy is a pioneer in the field of thermoelectric waste heat recovery. This presentation will discuss the application of thermoelectric devices for power generation from gas flares, automobiles, and large generator set exhaust streams. It will highlight design tradeoffs and challenges in implementation of thermoelectric power generation systems and present bench top testing and field operation data from Alphabet Energy’s proprietary PowerModule and PowerCard technologies. It will conclude with a summary of the critical criteria for application of thermoelectric energy harvesting devices and the elements essential to an effective system.
  • SESSION 5: POWER EXTRACTION CIRCUITS FOR OPTIMAL ENERGY HARVESTING, Instructed by Yogesh Ramadass, Texas InstrumentsWith the advent of IoT technology, a wide variety of electronic devices is expected to be deployed in often inaccessible places. Keeping these space-constrained devices powered up for their intended lifetimes is one of the primary concerns in the widespread adoption of this technology. In this talk, I will look at the energy needs of IoT devices, discuss the power delivery architecture and examine self-powered operation. The talk will delve into the basics of energy harvesting sources, storage mechanisms (batteries, supercapacitors) and the associated power management circuits needed (low-power DC/DC converters, chargers, cold-start circuits) to extend the operational lifetime of IoT devices.
  • SESSION 6: Solving the Energy Harvesting and IoT Power Consumption Measurement Challenges, Instructed by Seshank Malap, TektronixThe Energy Harvesting or Scavenging has been slowly gaining traction with advancement sensor technology and rise in demand for low power autonomous sensors and IOT applications. By itself, IOT devices are expected to exceed 20 billion units by 2020 and continue to have double-digit growth rates. Many of these devices will be wearable devices, portable medical devices, and battery-operated industrial sensor/transmitters and can benefit hugely from energy harvesting technologies. The core premise for success of these technologies is optimum energy generation, storage and consumption. To meet the design requirements, the designer needs to be able to determine the total power that energy harvesting can generate, store and the power that the end device will consume. It’s important to characterize storage system and precisely measure the power and load profiles in all these operation states. The harvester’s generation current and load current profiles can range for low micro amps to high amps depending on the end application. Furthermore the currents can be short bursts that can last for only 10’s of microseconds when the device harvesting energy or transmitting data. High sensitivity and speed are required to capture such load and power profiles. The storage component (batteries) also need to be precisely characterized for charge and discharge cycles to understand its role in the total system.
