Conducting Hydrogel Biopotential Electrodes
Clinical EEG recording is a useful technique both in neuroscience research as well as in the operating room, where it is used to monitor and study brain activity waveforms. However, contemporary electrodes require a great degree of skin preparation to perform properly. Our lab is studying the development of novel biopotential electrodes from a variety of conducting polymer and hydrogel materials to create a design capable of operating effectively with a minimum of prior skin abrasion and preparation. Such a design could prove extremely desireable in EEG applications, potentially reducing preparation time by over half and increasing the comfort level of the subject.
