摘要：
The invention relates to large area electrodes suitable for use in a fetal heart rate monitoring systems. The electrode comprises: a cutaneous gel contact (10) for sensing fetal electrocardiogram signals from a human pregnant subject； an electrical conductor (12) electrically connected to the gel contact (10) so as to define a first electrical contact region； a connector (14) in electrical contact with the electrical conductor (12) for connection to a lead wire； and a substructure (16) for attachment to a human pregnant subject. The gel contact (10) and the electrical conductor (12) are arranged on the substructure (16) to allow a contact surface (11) of the gel contact (10) to be in electrical communication with the skin of a human pregnant subject to define a second electrical contact region. The second electrical contact region has an area greater than 370 square millimeters. When arranged on a predefined electrode topology on the abdomen the success rate of fetal heart rate detection is significantly improved. The topology may be incorporated into a flat flexible cable which provides a comfortable and reproducible electrode arrangement allowing an untrained person to apply electrodes to a pregnant mother's abdomen.
