A method and apparatus for enabling the non-invasive acquisition of physiological parameters of a mammal, while allowing the mammal to move around a predetermined area is provided. In accordance with one example embodiment, a monitoring device for non-invasively acquiring physiological measurements of a mammal is provided. The device includes a first electrode configured to attach to an ear of the mammal in a manner suitable for obtaining a first electrical signal. A second electrode is configured to attach to a first alternate location of the mammal in a manner suitable for obtaining a second electrical signal. A third electrode is configured to attach to a second alternate location of the mammal in a manner suitable for obtaining a third electrical signal. The first electrode, second electrode, and third electrode are in communication with a signal receiver. Physiological parameters, such as those associated with electrocardiograms, can be obtained using the monitoring device.
