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: An internal heat-generating component noise correction technique can be used to improve accuracy of temperature sensing. In some examples, a method includes at an electronic device including a first temperature sensor and a first heat-generating component, measuring a first temperature using the first temperature sensor, and in accordance with a determination that one or more criteria are satisfied, compensating the first temperature based on a first estimate of heat generated by the first heat-generating component to generate a second temperature, and estimating a third temperature external to the electronic device using the second temperature.
