Biological electrode array
First Claim
1. A biological electrode array for connecting electrode apparatuses to the skin surface of a living body having a shape, the electrode array comprising:
- an insulating mount having a central area with a center therein;
a plurality of spaced-apart brush-tip electrodes extending from the central area of the mount, the electrodes extending outwardly further from the mount as their distance from the center increases; and
a plurality of protrusions extending from the mount further than the electrodes, the protrusions being spaced-apart about the brush-tip electrodes so the electrodes and the protrusions form a concave-shaped depression to conform to the shape of the living body, and each of the protrusions having a larger are than the brush-tip electrodes, whereby the protrusions prevent the brush-tip electrodes from penetrating the skin too far.

Abstract
A biological electrode array connects electrical apparatuses to the skin surface of a living body. The array includes an insulating mount having a central area. A case is connected to the mount and has a cavity with conductive shielding extending thereabout. A plurality of shielding electrodes extend from the insulating mount and are spaced-apart about the central area. The shielding electrodes are electrically connected to the shielding of the case. A plurality of spaced-apart brush-tip electrodes extend from the central area of the mount. Signal buffers within the cavity of the case are electrically connected to the brush-tip electrodes. Conductors extend from the cavity, each conductor being electrically connected to one of the buffers. The brush-tip electrodes have thin, but resilient wires, typically of hard stainless steel or tungsten.
