Abstract: An electronic device can detect whether the device is submerged in water using measurements from one or more electrodes. In some examples, the water detection can differentiate between a user contact with an electrode or the electrode submerged in water. In some examples, the detection of water can trigger water-related functions on device.

Abstract: Embodiments are directed to devices, systems and methods for determining a perspiration metric of a user. In some embodiments, a device may include a perspiration sensor having first and second electrodes positioned on a skin-facing exterior surface of the device. Capacitance circuitry may measure a capacitance between the electrodes, which may be used to calculate the perspiration metric. In some embodiments, the device defines a cavity such that one or both of the electrodes extend at least partially into the cavity. Other embodiments include a second perspiration sensor, and measurements from the second perspiration sensor may be used in calculating the perspiration metric.
