This activity took place on May 28th and it was carried out in the framework of the “Mile of Technology” / “Lange Nacht der Technik” at the Ilmenau University of Technology. This event is a major 3-annual exhibit of the Ilmenau University of Technology and adjunct institutions enabling the public audience to experience the world of science and technology and get a closer look into it. Along the Mile of Technology, more than 250 technology and science-related exhibitions, presentations and demonstrations are combined with cultural entertainment. Live demonstrations on various biosignal acquisition technologies including electroencephalography were performed by project fellows of the ANDREA project, using dry electrode technology, visual stimulation as well as online artefact rejection and source reconstruction. The future requirements, advantages and potential new applications of novel dry biosignal electrodes have been demonstrated and discussed showing several prototypes of the ANDREA project. Impacts on current and future research were highlighted in relation to other ongoing projects at the Institute of Biomedical Engineering and Informatics (BMTI). The event was open to a broad public audience of more than 15 000 visitors, including families, school and university students, scientists, media representatives and journalists. To summarize, the feedback on the research and education at the BMTI as well as in the frame of the ANDREA project was very positive.
