Smart Skin Electrodes for Electrophysiological and Circulatory Monitoring of Freely Behaving Humans

Wearable devices are becoming ubiquitous. They are used extensively by consumers and are becoming more noticeable in the medical domain. But contemporary wearable devices are still relatively bulky and often have limited equivalence to medical gold standards. Skin patches with chemical, mechanical, and electrophysiological sensors offer new opportunities for future sensors. These devices can be designed to seamlessly interact with the user while also providing high quality and long-term data. In combination with miniaturized low power electronics and powerful data analysis algorithms these devices have the potential to provide continuous measures of various physiological parameters from freely behaving humans. In this presentation I will discuss some of our recent achievements in monitoring the electrophysiology (EEG, EOG, EMG and ECG) of freely behaving humans during rest, overnight sleep and during movement. I will also present recent progress towards simultaneous measurements of electrophysiology and blood pulsation at the arm, neck, and face.
