Biopotential sensing technology with electrodes has a great future in healthcare and human-machine interface, whereas comfort and longevity are two significant problems during usage. Noncontact electrode is a promising alternative to achieve more comfortable and long term biopotential signal recordings than contact electrode. However, it could pick up significantly higher level of common-mode (CM) noise, which is hardly solved with passive filtering. The impedance imbalance at electrode-body interface is a limiting factor of this problem. In this work, we propose a practical approach to detect and monitor the electrode-body impedance imbalance change. Comparing with conventional approach, it has certain advantage in interference immunity, and good linearity for capacitance. Lastly, we show experimental evaluation results on the design. The results indicated the validity and feasibility of the approach. |
