E-learning in engineering studies - experience of the Ilmenau University...

The integration of e-learning elements and eassessments in the learning and teaching scenarios is more than 10 years standard at the TU Ilmenau. This concerns in particular the engineering studies. The used materials and tools are developed in the past at different faculties and thus very heterogeneous...

Novel cap system with active actuators for rapid dry electroencephalography

New fields of application for electroencephalography (EEG) require robust measurement technologies for ubiquitous mobile monitoring. Fast, easy and failsafe application as well as stable signal quality are crucial requirements for the electrodes. The application of novel dry EEG electrodes requires direct,...

Spike sorting algorithm for multichannel MEA recordings based on cross...

For evaluation of extra-cellular recordings with multi-electrode arrays (MEAs) an algorithm is needed to detect different types of cellular activity. The algorithm presented in this paper is based on correlation. It is an efficient and simple algorithm which is compared with the wave_clus toolbox. In...

Quantitative reconstruction of a magnetic nanoparticle distribution using...

Magnetorelaxometry (MRX) is a non-invasive method for the specific quantification of magnetic nanoparticles (MNP). Here, we investigate experimentally the reconstruction of the MNP concentration in an extended volume. A phantom with varying but known MNP distribution was subsequently magnetized by 48...

Correlation between autonomic dysfunction and impaired microcirculation...

Patients suffering from schizophrenia have an increased mortality risk due to cardiovascular events that might be associated with cardiac autonomic dysfunction. The aim of this study was to analyse the interdependencies between indices of autonomic regulation from heart rate and blood pressure variability,...

Mne-X: MEG/EEG real-time acquisition, real-time processing, and real-time...

Providing millisecond-temporal resolution for non-invasive mapping of human brain functions, Magneto-/Electroencephalography (MEG/EEG) is predestined to monitor brain activity in real-time. While data analysis to date is mostly done subsequent to the acquistion process we introduce here an acquisition...

Influence of skull defects on MEG source reconstruction in an in-vivo animal...

Quantitative experimental evidence for the influence of skull defects on the MEG is rare. This study aims to experimentally investigate the influence of conducting skull defects on the MEG and EEG signal and source reconstruction using a controlled current source under a skull defect and a detailed finite...

Test environment for hydrogels as functional sensor window

Sensors in contact with biological environments still suffer a lack of stability due to biological attacks. A functional sensor interface that does not influence the analyte path to the sensor nor the measured signal but protects the sensor from these attacks may be realized by using hydrogels. To minimize...

Comparison of different conductive fillers in silicone for the purpose...

Graphite (G), Carbon Black (CB) and Carbon Nanotubes (CNT) are compared regarding their usability as conductive filling particles in medical silicone. Produced test structures were characterized mechanically and electrically. CNT turn out to produce the lowest electrical resistance at the lowest concentration....
