Radical developments in material science, telecommunication and sensor technology are about to transform the way of engineering design is conceived and carried out. In the next ten years smart materials and structures, with embedded sensors and systems capable of self-diagnosis, will be part of our life, from simple goods to civil buildings. These elements will be permanently connected through a distributed network so that owners, users, and everybody involved in the management process – connected via the Internet – can check the condition of the elements during production, transportation, installation and operation.
The scope of the School is to provide an overview of smart technologies from a cross-disciplinary perspective with special focus on fiber optic sensors, smart materials, nano- and micro-technologies, wireless sensor networks, autonomous mobile sensors, control devices, nondestructive evaluation, data analysis and decision making.

VENUE & TRAVEL
School venue
The school will be held at the "Aula 5" of the Faculty of Law (Facoltà di Giurisprudenza) of the University of Trento (Via Verdi 53, 38122 Trento), located in the city center, close to the Cathedral (Piazza Duomo) and 10 minutes walk from the railway station.
About Trento
Trento is a beautiful city in the heart of the Dolomites, near Lake Garda. The center has a strong Renaissance character with many beautiful frescoed buildings, some built to accommodate delegates to the Council of Trent (1545-1563). The Trento surroundings offer beautiful naturalistic tracks in high mountains, with many lakes and ancient castles.
Worth a visit:
- Castello del Buonconsiglio: this castle is a "must see" attraction as it represents the main monument of the city.
- Duomo: the Duomo of Trento, also known as Saint Vigilius Cathedral, is located in the main square of Trento.
- Palazzo delle Albere: a representative villa, built in Renaissance style, now hosting a permanent modern art museum.
- Museo diocesano tridentino: next to the Duomo, Palazzo Pretorio hosts a permanent exhibition.
- Roman ruins: in Piazza Battisti you can access the ruins of ancient Trento built by the Romans. This is actually another city under Trento.
Close to Trento
Levico – Caldonazzo - Garda lakes. The lakes are perfect for both relaxing in the sun and for water sports. In particular, Lake Garda is the largest and most important lake in Italy, every year attracting thousands of tourists from all over the world, the surrounding towns and offering many attractions and events.
MART Museum of Modern and Contemporary Art of Trento and Rovereto - Over 12,000 paintings, drawings, prints and sculptures today constitute Mart’s rich holdings.
Castel Toblino - An impressive landscape: a medieval castle surrounded by a small lake among the mountains.
How to get to Trento
By car or coach
You can reach Trento by the following roads: Strada Statale dell'Abetone e del Brennero; Autostrada del Brennero – A22 motorway; Strada della Valsugana for those coming from Venice; and Strada Statale 45 bis (Gardesana Occidentale) for those coming from Brescia.
By train
Two main lines reach Trento: the Brennero line (from Rome to Innsbruck) and the Valsugana line (from Venice to Trento).
Timetable details: Reiseauskunft; Trenitalia
By plane
The closest airports to Trento are the following:
Verona Catullo Airport – 90 km
Venezia Marco Polo – 125 km
