M07 Power efficiency: Power efficiency in the design of Smart IoT devices

Chair:
Enrico Macii, Politecnico di Torino, IT

The first session of this Tutorial includes two lectures. The first one provides an introduction to the IoT systems and the most promising application fields, highlighting the energy-related issues. The second one lists and analyses the general methodologies that can be applied to tackle energy challenges for IoT devices.

Internet of Things applications are becoming a reality in a multitude of fields,e.g., from consumer applications to environmental monitoring, from energy distribution to the so-called "smart factory". Pervasive intelligent and connected systems introduce new functionalities and services, but system design is severely constrained in terms of cost, required security and energy. This lecture describes some IoT applications focusing on the energy aspects, illustrating where most of the power is used and highlighting the main challenges that need to be tackled by the circuit and system designers.

This lecture describes state-of-the-art solutions for energy evaluation and optimization addressing computation, communication and power delivery for the devices involved in IoT applications.

The second session of the Tutorial adopts a more practical approach. The first lecture goes into the details of energy harvesting and conversion, while the second one shows related industrial system development experience.

The IoT paradigm requires a careful choice of energy sources, conversion and storage methodologies, taking into account the specific application that is being developed. This lecture shows some of the available methodologies and provides hints for the design of optimized systems.

From the point of view of system designers, this lecture describes the process that goes from the idea to the implementation of an IoT system, including system-level modeling, the selection of commercially available components (sensors, processing and communications) and optimized system management.
