Abstract: An electronic device may include a housing and relative humidity sensor in the housing. The relative humidity sensor may include an optical layer, a relative humidity-sensitive layer coupled to a surface of the optical layer, a light emitter that emits light into the optical layer, and a light detector that detects light that has reflected within the optical layer and off of the relative humidity-sensitive layer. The relative humidity may be determined based on the light detected by the light detector. The optical layer may be a layer with angled edges, a prism, a Bragg reflector, or a waveguide. A reference light detector and/or a temperature sensor may be included in the relative humidity sensor, and measurements from these additional sensors may be used in determining the relative humidity. In this way, an optical relative humidity sensor may be formed in the electronic device.

Abstract: An electronic device may include a housing and relative humidity sensor in the housing. The relative humidity sensor may include a relative humidity-sensitive layer, a light emitter that emits light into the relative humidity-sensitive layer, and a light detector that detects light that has passed through the relative humidity-sensitive layer. The relative humidity may be determined based on the detected light. For example, the light may be measured interferometrically to determine a path length of the light to determine the relative humidity. Alternatively, the light may be scattered by plasmonic nanoparticles in a relative humidity-sensitive material to determine the relative humidity. As other examples, polarized light may pass through the relative humidity-sensitive layer and measured to determine the relative humidity, or light may be used to form sound waves that may be measured to determine the relative humidity.

Abstract: Embodiments are directed to an electronic device that includes a housing, a light emitter, a first detector positioned at a first separation distance from the light emitter, and a second detector positioned at a second separation distance from the light emitter. The electronic device can include a processor that is configured to cause the light emitter to emit light toward a user, receive a first measurement from the first detector based on a return of the emitted light from tissue of the user and receive a second measurement from the second detector based on a return of the emitted light from the tissue of the user. The processor can determine a decay constant of the emitted light using the first measurements and the second measurements, and determine a water content metric of the user using the determined decay constant.
