Classification: CPC A | IPC A

Claim 0:
1. A physiological sensor comprising:
a sensing element to detect a physiological information from a patient's skin, wherein the sensing element is one of a temperature sensor, a pulse oximetry sensor, flow sensor, pressure sensor, or a respiration sensor;
a substrate configured to hold the sensing element on the patient's skin;
a plurality of contact probes arranged around the sensing element on the substrate, wherein the contact probes are positioned on the substrate such that they are in galvanic contact with the patient's skin when the substrate is fully contacting the patient's skin;
a controller configured to measure impedance along impedance paths between the plurality of contact probes and determine whether the substrate has lifted from the patient's skin based on the impedance; and
wherein at least one impedance path extends between contact probes on opposite sides of the sensing element such that the at least one impedance path extends across the sensing element.
