Dry Electrodes Ease Long-Term ECG Monitoring

Jan-23-15 A new dry electrode sensor system can monitor a patient's ECG and EMG continuously and with much less discomfort.

While continual, long-term monitoring of a person's ECG has proven to be a helpful diagnostic tool, the electrodes must be kept wet—which can aggravate the patient's skin. Additionally, the gel used to keep the electrodes wet will eventually dry up and reduce the sensor's accuracy.

In contrast, the new device from North Carolina State University is equipped with silver nanowires within a flexible polymer. The nanowire sensors do not require a gel layer in order to read the body's electrical signals, and their signal is comparable to that of the wet sensors. And because the nanowires are able to flex and conform to the patient's skin, they maintain good contact even while the person is moving.
