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. A monitoring system for monitoring of a physiological activity of a recipient, comprising a set of electrodes having a working surface to be brought into a contact with the recipient'"'"'s skin, said system being characterized in that each electrode comprises a body of an electrically conductive elastic material with the working surface exhibiting projections so as to enable a substantially constant position of the contact with the recipient'"'"'s skin.

2. A system according to claim 1, characterized in that the projections are arranged in a substantially uniform distributed pattern over the working surface with spacings between them.

3. A system according to claim 2, characterized in that the projections comprise metal particles.

4. A system according to claim 1, characterized in that the electrode body is sandwiched between two layers of insulating material, tips of the projections being arranged to extend beyond a body of a isolating layer.

5. A system according to claim 1, characterized in that said system is a cardiac arrest monitoring system.

6. A system according to claim 1, characterized in that the electrodes are mounted on a fabric-based elastic belt of a wearable garment.

7. An electrode structure for use in a monitoring system according to claim 1.
