A kind of physiological monitoring system and method measure at least one physiological parameter using the first low energy biosensor, to generate the signal and high-energy biosensor of the first biosensor, to generate the signal of the second biosensor. Motion sensor motion reference signal generate mode selector switch used to to select the biosensor of the first low energy biosensor or the second energy. Optionally, when moving the signal of the second biosensor of relevant embedded components, by mode selection switch, for selecting the first low energy sensor or the second energy sensor.
