Tutorial Title:

Technologies and devices for Internet of Things and Edge Computing



Chair: Adrian M. Ionescu (EPFL, Switzerland)

Venue: Medium Aula B



In the future, major innovations will require holistic approaches encompassing silicon and cloud technologies in the context of big/abundant data analytics. There is still a very important role to be played by innovations in energy efficient technologies, devices, and system architectures and design, building on the success of silicon CMOS. This tutorial is addressing some of the stringent challenges of Internet of Things and Edge Computing in terms of energy efficient technologies, sensor network architectures, energy harvesting, power management and the design in most advanced low power CMOS technologies such as Ultra-Thin Body Fully Depleted Silicon On Insulator. The speakers will detail the state of the art in the field and will illustrate their talks with concrete examples and implementations. A particular attention will be dedicated to the use of IoT in medicine and smart living.

1. Adrian Ionescu, EPFL, SwitzerlandEnergy efficient technologies and devices for enabling Artificial Intelligence at the Edge: an Overview

Abstract:Analysts predict that by 2025 AI-related semiconductors will account for 20% percent of all semiconductor demand, corresponding to a $67 billion in revenue, at a growth rate that is 5x higher than the one in conventional semiconductor applications. This overview includes major trends in basic hardware technologies needed to support the Artificial Intelligence Applications at the Edge: energy efficient sensing, computation and communications. We will illustrate some of the most promising trends in wearable computing and sensing. We will also highlight the importance of more decentralizing strategies in AI, as the new breathing of the computer industry, with edge computing is a natural next step.

2. Thomas Skotnicki, CEZAMAT, Poland – Energy harvesting and power management for sub-milliWatt IoT nodes (I)

Abstract: Internet of Things involves a huge number of communicating devices deployed in our environment as well as in surrounding objects. Related to Iot terms such as: Smart Planet, WSN (wireless sensor nets), Swarm, TSensors (trillion sensors), Internet of Everything, M2M (machine to machine), Smart Dust, etc. give an idea of the global and ubiquitous dimension of IoT. The economical aspect of IoT is also hard to be overestimated since none of the former High Tech revolutions has reached the volume of trillion unit market. This new enormous dimension of the market sets many new technical challenges, and among them the question of powering the IoT devices. The usage of batteries for this purpose could seem the simplest and the most natural, if not the fact that IoT devices will be often placed in inaccessible loci (in the volume or elements of constructions, buildings, machines, cars, industrial installations, urban infrastructure, rural vast areas, etc.). Changing trillions of batteries periodically may thus turn out to be more difficult and costly than their fabrication and deployment. Therefore, energy self-sustainability or self-powering of IoT devices is considered a key feature. In this SC we will deliberate on main kinds of energy harvesters (PV, TEGs, vibrational, EM and RF). We will explain their operation principles, pros and cons, their state of the art, and their development perspectives and challenges.

3. Mathieu Coustans, EM Microelectronic, Marin, Switzerland and Maher Kayal, EPFL, Switzerland – Energy harvesting and power management for sub-milliWatt IoT (II)

Abstract: Computing at the edge, in the fog, or in the cloud is Building on the success of scaling of silicon CMOS. Nowdays mm3 computing defines the state of the art in terms of integration including the whole functions needed to operate an edge node in the sub-milliWatt region. Such computers are comparable to a grain of sea salt. In this context, there is still a very important role to be played by innovations in energy efficient technologies, devices, design, and system architectures. This tutorial paper is addressing some of the stringent challenges of Internet of Things and Edge Computing in terms of energy efficient technologies. It attempt at providing  some scaling number based estimation of the power load and a focus on power management and energy harvesting circuits in CMOS technologies.

2. Stephane Monfray, ST Microelectronics, France – Designing ultralow power IoT systems with UTBB FD-SOI

Abstract: As IoT market is booming, the role of energy harvesting will be a key enabler for the development of abandoned sensors. Thanks to the conjunction of ultra-low power electronic development and by changing the paradigm of energy harvesting, the integration of autonomous sensors and electronics with ambient energy harvesting will be achievable. The tutorial will address innovative solutions for implementing optimized systems to demonstrate complete ultra-low power autonomous wireless sensors working with µW power, and we will focus on solutions offered by CMOS compatible technologies: FDSOI low power circuits, innovative power management to optimize energy harvesting, and what silicon technologies can provide for innovative energy harvesters.
