Embodiments provide physiological measurement systems, devices and methods for continuous health and fitness monitoring. A wearable strap may detect reflected light from a user's skin, where data corresponding to the reflected light is used to automatically and continually determine a heart rate of the user. The wearable strap may include a motion sensor that is used to determine a motion status of the user. Based upon the motion status of the user, the system may activate light emitters on the wearable strap to determine the heart rate of the user.

A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a fiducial marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

A process of capturing a biopotential signal at a surface of a body includes using a sensor receiver which forms a first signal connection with the body wherein one or more parameters of impedance of the first signal connection are unknown. The biopotential signal is received at an output of a first signal channel having a first transfer function dependent on the one or more unknown first impedance parameters. The biopotential signal is received at an output of a second signal channel having a second transfer function dependent on the one or more unknown first impedance parameters. The process also comprises deriving a set of relations for the biopotential signal based on the transfer function of the first signal channel, the transfer function of the second signal channel, and outputs of the first and second signal channels. The set of relations is solved to determine the captured biopotential signal.
