Non-Contact ECG Sensing Employing Gradiometer Electrodes

Contact dermatitis to self-adhesive ECG electrodes.

Unusual suction-like contact dermatitis due to ECG electrodes.

A non-atopic 74-year-old man complained of itching vesicular dermatitis on the left side of his thorax, which had flared up 8 days earlier, after a prolonged ECG monitoring. On inspection, many tense erythematous vesicular lesions, strictly arranged in a ring-shape, were observed at every site of application of the electrodes (Fig. 1). Due to the particular shape of the dermatitis a suction rea...

A Low-Power Portable ECG Touch Sensor with Two Dry Metal Contact Electrodes

This paper describes the development of a low-power electrocardiogram (ECG) touch sensor intended for the use with two dry metal electrodes. An equivalent ECG extraction circuit model encountered in a ground-free two-electrode configuration is investigated for an optimal sensor read-out circuit design criteria. From the equivalent circuit model, (1) maximum sensor resolution is derived based on...

Wearable Textile Electrodes for ECG Measurement

The electrocardiogram (ECG) is one of the most important parameters for monitoring of the physiological state of a person. Currently available systems for ECG monitoring are both stationary and wearable, but the comfort of the monitored person is not at a satisfactory level because these systems are not part of standard clothing. This article is therefore devoted to the development and measurem...

Novel dry electrodes for ECG monitoring.

The development, fabrication and characterization of two novel dry bioelectrodes--conductive and capacitive ones--for biopotential monitoring are presented. The new electrodes have the potential to improve the applicability of dry electrodes in ambulant recording of ECG by reducing motion artifacts as well as the contact impedance to the skin. Furthermore, a passive filter network is integrated...
