A method of communicating with a physiological sensor is disclosed. In an embodiment, the method includes supplying power through a first conductor in a first mode to the physiological sensor and communicating with an information element through the first conductor in a second mode. The physiological sensor includes the information element, a power supply configured to receive and store power from the first conductor in the first mode, and sensing circuitry configured to receive power from the first conductor in the first mode. The power supply releases the stored power to the sensing circuitry in the second mode.
