Electrode array system for measuring electrophysiological signals
First Claim
1. An array of electrodes, including only three electrodes, for monitoring physiological electrical signals, said array comprising:
- a flexible unitary body having a main portion, one satellite portion, and a flexible portion located between said main portion and said one satellite portion;
two electrodes of the three electrodes being printed on said main portion and a third electrode of the three electrodes being printed on said satellite portions;
conductors printed on said flexible unitary body to carry signals from said electrodes.

Abstract
An array of electrodes is constructed to allow the user to easily adjust to the correct size of the patient'"'"'s head. The array is self-adhesive, pre-gelled and disposable. The array fits easily over the temple and forehead areas where EEG signals can be acquired by specially designed monitors for purposes of monitoring a number of bodily phenomena, including but not limited to, depth of anesthesia, and/or ischemia, and burst suppression. The array is connected to the monitor via a tab connector that is integral to the disposable device. The tab connector is insertible into a reusable connector that is part of a monitoring system.
