Summer School 2017

2017 Summer School of Information Engineering,

Technologies for Energy Sustainability

This “Summer School” is dedicated to the study and analysis of the technologies of the “Information and Communication Technology, ICT” applied within the Energy savings, both from a technological point of view (innovative microelectronic devices) and from the point of view of communication networks .

In particular, this summer school was conceived and structured as a dissemination vehicle for two European projects he sees as participants the two teachers of the school organizers:

Project InRel-NPower (, which sees Prof. G. Meneghesso as Project Coordinator, which has as its objective the development of new electronic devices and systems to reduce energy losses from energy conversions.

Project SCAVENGE (, which sees the prof. Michele Rossi as Prime Investigator, which has as its objective the design of architectures and algorithms for cellular networks 5G new generation that are efficient and able to harness the energy that can be derived from the external environment.


Efficient power conversion systems are at the heart of the worldwide effort for a green economy, since they can minimize losses and save energy. Semiconductor power devices are a central part of any power conversion circuit and are ubiquitous in our daily lives: they transform voltages for a multitude of appliances, such as from the 220V AC mains to a 12V DC end-user appliance and enable to convert from DC (such as a battery in an electric car) to AC (such as a motor drive) and vice versa. Highly efficient power switching devices are a key for successful introduction of full electric vehicles into the market. The InRel-NPower project aims to contribute to this world-wide challenge through the development of GaN- and AlN-based power devices.


The fifth generation 5G of mobile technology will support 1,000 times more capacity per unit area than 4G, for more than 100 billion devices with typical user rates of 10 Gb/s, and significantly lower latency and higher reliability. The higher capacity demanding human-centric communications will be complemented by an enormous increase in the number of communicating machines. However, this enormous growth in the number of devices and access points will also lead to an equally large growth in the carbon footprint of the information and communication technologies (ICTs). Connecting this dense network of BSs to the energy grid, and regularly recharging drained end device batteries is physically impractical, if not impossible. SCAVENGE tackles sustainable design, protocols, architectures and algorithms for next generation 5G cellular networks. Our overall purpose is to allow mobile systems and especially their constituting base stations, femto, small-cells, mobile devices and sensors to take advantage of sources harvesting ambient energy (such as renewable sources).
