The secondment of Dr. Frank Zanow took place from May 1st until July 31st 2015 from eemagine Medical Imaging Solutions GmbH (Industry, Berlin, Germany) to Technische Universität Ilmenau (Academia, Ilmenau, Germany). During parts of the secondment Frank Zanow was joined by Dr. Lars Matthäus (eemagine Medical Imaging Solutions GmbH). The main focus of the performed work by Frank Zanow during his secondment was on tasks work package 2 (2.2, 2.3, 2.4) as well as work package 3 (3.1, 3.4) and work package 4 (4.1, 4.3, 4.4). The most recent electrode and cap prototypes – manufactured in cooperation by UPorto, TUIL and EEM, have been tested extensively at TUIL. Frank Zanow also contributed to a study regarding dependencies between electrode adduction, substrate flexibility and patient comfort. Consequently, different textile and silicone based positioning and adduction mechanisms as well as textiles with different cuts have discussed, specified and developed. Specification of space, interface, electrical performance and other environmental requirements of the overall system where defined and documented. Different interfacing techniques and materials between electronics and electrodes have been assessed and tested using Rapid Prototyping at TUIL. Using state-of-the-art amplification hardware, the single- electrode and multichannel prototypes have been combined with standard EEG hard- and software in order to test interfacing and software requirements prior to implementation of technology-specific alterations. First signal acquisition studies on multiple volunteers have been performed in direct comparison with conventional wet cap systems. Therefore, different test situations (resting, sitting, relaxing, evoked potentials, artifact induced) have been simulated during the EEG acquisition tests. Frank Zanow contributed to the works at TUIL with extensive knowledge about electronics and software design. He also contributed with customer-oriented and production-specific considerations and requirements in all work package tasks.
