Patent ID: 8892181

Claim:
A system for monitoring fetal electrical activity, the system comprising: a plurality of contact elements, each of the plurality of contact elements configured for attachment to an external skin surface of a pregnant female; and at least two sets of electrodes associated with each of the plurality of contact elements such that electrodes of each set contact the external skin surface of the pregnant female when the associated contact element is attached, the at least two sets of electrodes comprising a first set of electrodes arranged in a first pattern and a second set of electrodes separate from the first set of electrodes and arranged in a second pattern distinct from the first pattern, each of the plurality of contact elements having its sets of electrodes configured in a unique pattern such that at least one electrode from a first contact element and a corresponding electrode from a second contact element form a cross-body lead, fetal electrical activity being detected by the electrodes when the contact elements are attached.
