Abstract: Systems, methods and devices relating to a physiological sensor system to be worn on a subject's skin to measure, process or store one or more physiological parameters, the system comprising: at least one pair of sensing electrodes that measure, when in contact with the subject's skin, physiological signals indicative of the one or more physiological parameters; first and second reference electrodes that concurrently provide a source signal and a reference signal for said sensing electrodes in their measurement of the one or more physiological parameters; and a subject-securing device for securing said sensing electrodes and said first and second reference electrodes against the subject's skin in operation.

Abstract: The present invention relates to an apparatus and method for the non-invasive analysis of physiological attributes, such as heart rate, blood pressure, cardiac output, respiratory response, body composition, and blood chemistry analytes including glucose, lactate, hemoglobin, and oxygen saturation. Using a combination of multi-functioning disparate sensors, such as optical and electrical, improvements are made over existing physiological measurement devices and techniques. The special configuration of one or more multi-functional sensors is used to non-invasively measure multi-wavelength optical plus one or more of ECG, Bio-impedance, and RF-impedance spectroscopic data.
