Abstract: Detecting user contact with one or more electrodes of a physiological signal sensor can be used to ensure physiological signals measured by the physiological signal sensor meet waveform characteristics (e.g., of a clinically accurate physiological signal). In some examples, a mobile and/or wearable device can comprise sensing circuitry, stimulation circuitry, and processing circuitry. The stimulation circuit can drive one or more stimulation signals on one or more electrodes, the resulting signal(s) can be measured (e.g., by the sensing circuitry), and the processing circuitry can determine whether a user is in contact with the electrode(s). Additionally or alternatively, in some examples, mobile and/or wearable device can comprise saturation detection circuitry, and the processing circuitry can determine whether the sensing circuitry is saturated.

Abstract: Embodiments are directed to a wearable device that can include a housing, a touch-sensitive display coupled to the housing, a band coupled to the housing and configured to secure the housing to a user, and a plurality of electrodes that contact the user when the wearable device is worn by the user. The wearable device can be configured to cause the plurality of electrodes to apply electrical signals to the user, measure the electrical signals from the user using the plurality of electrodes, generate a set of impedance data from the measured electrical signals, and identify one or more respiratory cycles using the set of impedance data.

Abstract: Embodiments include a system for analyzing breathing parameters of a user. The system can include an optical sensing unit configured to detect movement of a torso of the user and output one or more signals indicative of the movement of the torso. The system can also include an electronic device configured to request for the user to breathe according to a breathing profile during a time period. The system can include a processing unit configured to receive the one or more signals generated by the optical sensing unit during the time period and determine an adherence metric using the one or more signals and the breathing profile, where the adherence metric indicating a correspondence between movement of the torso and the breathing profile requested during the time period.

Abstract: Embodiments include a system for measuring respiratory function of a user. The system can include an optical sensing unit configured to detect movement of a torso of the user. The system can include an electronic device configured to provide a first request for the user to breathe at a first rate during a first time period and a second request for the user to breathe at a second rate during a second time period. The system can include a processing unit configured to determine a first respiration parameter based on the movement of the torso during the first time period and determine a second respiration parameter based on the movement of the torso during the second time period. The processing unit can determine a level of respiratory function based on the first respiration parameter and the second respiration parameter.

Abstract: An electronic device includes a surface such as a cover glass, a first group of electrodes coupled to the surface and arranged in a first direction with respect to the surface, a second group of electrodes coupled to the surface and arranged in a second direction with respect to the surface, a dielectric separating the first and second groups of electrodes, and a controller electrically connected to the first and second groups of electrodes. The controller is operable to detect a touch of an object to the surface using a mutual capacitance between the first and second groups of electrodes and determine a non-binary amount of force exerted based on resistances of the first and second groups of electrodes.
