Original Abstract Submitted
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. in this way, a light-based relative humidity-sensor may make relative humidity measurements.
