Abstract
A device configured to detect a physiological signal of a patient includes a monitor portion and one or more electrode portions. At least one of the electrode portions is made as a non-contact electrode or a dry electrode, with further adjustments according to embodiments. The electrode portion includes a substrate that has a back side and a front side that is configured to be brought proximately to the patient. At the front side, a sensing electrode may detect a patient signal, and a guard electrode may protect this detection by having a suitable shape, such as a ring. At the back side, a circuit may generate an output signal from the detected signal, and couple it to an output conductor. Moreover, the adjustments may include that the circuit can couple a version of the output signal to the guard electrode.
