A Dry ECG Recording System for the Ambulatory Monitoring of the Human Electrocardiogram

Soumyajyoti Maji, Trinity College Dublin
ABSTRACT:
Currently, gel-less electrodes are primarily employed in heart-rate monitors used
largely in the field of sports and athletics. These devices only measure and display
the value of the wearer’s heart-rate on a beat-to-beat basis. This information is
largely used in an athletic training capacity rather than any clinical role. While these
devices detect the ECG signal they do not preserve the morphology or profile of
the signal which carries the clinical information on the state of the heart and
cardiovascular system. This makes it easier to detect only the presence of the
heartbeat and to suppress interference and artefactual signals which are
generated by the movement and vigorous activity of the wearer of the device.
Electrical characterization of the electrodes will provide knowledge not already
available, which is essential for the correct interfacing of the electrodes with the
recording amplifier. The performance requirements of the recording amplifier and
conditioning circuitry in a dry electrode scenario is an order of magnitude more
stringent than is the case using standard adhesive electrodes. This seminar will
provide the suggestions and recommendations in developing dry ECG recording
system for ambulatory monitoring of the human electrocardiogram.
