1. A biomedical sensor, comprising:

  • a) a sensor body having a skin-facing surface and an opposed surface;

    b) a plurality of conducting elements disposed at least partly over the skin-facing surface;

    c) a sensing element connected to the conducting elements, so that the sensing element detects a signal representative of a physiological parameter of a body facing the skin-facing surface using the conducting elements;

    d) an indicator spaced apart from the skin-facing surface, the indicator including plural separately-activatable visual indicators;

    e) a storage device storing a physiological model; and

    f) a processor coupled to the sensing element, the indicator, and the storage device, so that the processor determines a quality of sensor placement by comparing the signal to the stored physiological model and operates the indicator to provide a human-perceptible indication of the determined quality; and

    wherein the processor is configured to activate none of the visual indicators if the signal corresponds to an absence or failed detection of the physiological parameter;

    to activate a selected first positive number of the visual indicators if the signal is not consistent with the physiological model; and

    to activate a selected second positive number of the visual indicators if the signal is consistent with the physiological model, the selected second positive number being greater than the selected first positive number.
