Ionic Liquid Gel-Assisted Electrodes for Long-Term Cutaneous Recordings

Ionic Liquid Gel-Assisted Electrodes for Long-Term Cutaneous Recordings DOI: 10.1002/adhm.201300614

The integration of an ionic liquid gel on conformal electrodes is investigated for applications in long-term cutaneous recordings. Electrodes made of Au and the conducting polymer PEDOT:PSS coated with the gel show a low impedance in contact with the skin that maintains a steady value over several days, paving the way for non-invasive, long-term monitoring of human electrophysiological activity.
