Electrodes providing excellent recording and physical stability. The
present invention encompasses electrodes that include a plurality of
small teeth that possess a novel design shape and orientation. The
shallow and relatively long teeth preferably run parallel to the rim of
the electrode that presses against the patient's skin. When the electrode
is twisted onto skin, the tiny teeth penetrate the stratum corneum and
move nearly horizontally under the stratum corneum, thus anchoring the
electrode securely to the skin. The electrodes of the present invention
cause minimal discomfort to the patient since the small teeth do not
extend to the pain fibers which are located in deeper layers of the skin.
The electrodes may house a wide diversity of electronic components to
enable numerous experimental and medical implementations. The electrodes
the present invention may also be used wirelessly either singularly or as
an array so that no electrode leads extend away from the patients body.
The electrodes of the present invention may be fabricated using precision
photo-chemical etching techniques that are well known in the art. The
present invention also includes an electrode installation device that
preferably employs the electrodes of the present invention.
