A new photonic quantum dew point sensor has been developed by NIST researchers. The sensor determines the dew point of an analyte by using a common substrate with multiple components:
1. A photonic dew sensor exposed to the analyte for direct contact
2. A photonic temperature sensor on the same substrate
3. An optomechanical temperature sensor on the substrate
4. A heater on a separate dew sensor substrate to heat the photonic dew sensor above the analyte’s dew point
5. A temperature sensor substrate between the common substrate and the other temperature sensors
6. A sensor cover to prevent analyte contact with the temperature sensors
The sensor can be used in a relative humidity sensor system along with a secondary temperature sensor. The technology could enable more accurate humidity measurements in various applications, though specific implementation details and timelines were not provided in the article.
