In the future, objects and people will be almost permanently connected and exchanging information in the so-called Internet of Things (IoT). While the potential influence of IoT in our daily life is enormous, there are major challenges related to its energy sustainability.

Also in the healthcare domain, progress in microelectronics has enabled the miniaturization of data processing elements, radio transceivers and sensors for medical applications. However, the inherent resource-constrained nature of these systems, coupled with the specific operating conditions and the stringent autonomy requirements pose important design challenges. The evolution of battery energy density is below the curve of Moore’s law thus making power consumption the limiting factor of next-generation smart systems. Furthermore, technology allows integrating various types of energy harvesting devices, which are able to scavenge energy from the environment thus potentially compensating the increased gap between the energy demand and its availability. This tutorial addresses all these issues involving energy management in autonomous wireless devices from a novel perspective. As a matter of fact, while the analysis and the optimization of how energy is consumed in electronic systems has been the subject of many studies, a lot of misconceptions are still around when it comes to how optimally generate, store, convert and distribute the energy available in a system that incorporates energy generation and storage devices.

The tutorial will cover the following key topics:

  1. Architecture of wireless autonomous smart systems and design challenges
  2. Energy storage devices: background and non-idealities, models and design guidelines, conversion issues
  3. Energy harvesting techniques and architectures for energy neutral systems
  4. Power management policies and protocols for autonomous objects
  5. Modeling and simulation techniques
  6. Trends for future wireless smart systems

The presentations will report results from SMAC and CONTREX European projects and will be accompanied by actual case studies, showing how the presented concepts support the design and verification of wireless autonomous smart systems.

The tutorial is targeted towards students and pratictioners belonging to both academia and industry and concerned with design of advanced wireless embedded systems (e.g., wearables, smart metering, body sensor networks, etc).
