Social Fabric

For three years, researchers from the University of Copenhagen and the Technical University of Denmark harvested and analysed data activity from up to 1,000 students’ smartphones as part of the Social Fabric project, and the researchers now have precise knowledge of how, when and how much the young people communicate with their fellow students. The data shows whether the students talk on the phone, write texts, emails or Facebook messages, or meet physically.

The project was part of the UCPH Excellence Programme for Interdisciplinary Research.











An important part of the Social Fabric project was SensibleDTU experiment: the collection of a data set of hitherto unprecedented size and quality by the distribution of smart phones to 1000 newly started students at the Technical University of Denmark. The phones came equipped with an app that collected data on social interactions among the students on all relevant channels: face-to-face (via Bluetooth), sms, phone conversations, email and online social networks.

The data not only served the researchers but also the participants themselves. A focus area of the DTU project was to innovate how the data could be made available and useful for the students.

The experiment had its own website (, but the website no longer exists.

Participation was only open for DTU Students in their bachelor’s degree during the academic year 2013-14.
