Abstract

An electrode structure for use with a monitoring system. A thin flexible body of an electrode material comprising conductive rubber is provided with projections extending externally to a working surface. According to this construction of the working surface of the electrode only the projections make a contact to the recipient'"'"'s skin. When the projections are provided with a small cross-section, the constant electrode-skin contact is ensured due to the resiliency of the electrode material.

Claims

1. An electrode for use in a monitoring system, the electrode comprising:

a layer of electrically conductive elastic material;

a plurality of submillimeter-sized prefabricated conductive metallic elements inserted in and projecting from a skin contacting face of the layer of electrically conductive elastic material, which metallic elements have surfaces configured to contact skin of a patient to be monitored; and

an insulating plastic layer covering the skin contacting face of the electrically conductive elastic material with the surfaces of the conductive metallic elements projecting through the insulating plastic layer to contact the skin.

2. A monitoring system for monitoring a physiological activity of a recipient, comprising:

a set of sensors including electrodes according to claim 1 to acquire physiological data;

a device connected with the sensors to interpret the acquired physiological data.

3. The electrode according to claim 1, further including a plurality of ventilation holes extending through the electrically conductive elastic layer.

4. The electrode according to claim 1, wherein the layer of electrically conductive elastic material is mounted to an interior of a wearable garment.

5. The electrode according to claim 1, wherein the electrically conductive elastic material includes an electrically conductive rubber.
