Smart dosimeter for personal solar exposure

Enables live monitoring of personal sun exposure for health & wellbeing exposome assessment and for clinical research studies (e.g. outdoor workers, sunscreens use, vitamin D,..).

  • No need of solar sensor devices or smartphone exposure to sunlight, just the App running in background on the smartphone (even kept in a purse or pocket).
  • Real-time tracking of the user sun exposure dose via web-portal analytics.
  • Whole body sun exposure mapping.
  • Photobiological effective irradiance weighted according to any action spectrum.
  • No calibration needed thanks to Earth Observation satellite imagery and GNSS analytics.

Performances

Enables live monitoring of personal sun exposure for health & wellbeing exposome assessment and for clinical research studies (e.g. outdoor workers, sunscreens use, vitamin D,..).

  • Effective solar dose accuracy: 9.1% maximum error (MAE) on horizontal plane (tested for UV erythemal at mid-latitude)
  • Weighted global solar irradiance: obtained by 1 nm spectral convolution
  • Whole body sun exposure mapping: any number of body sites at 2 cm² resolution
  • Real-time sun exposure dose tracking update: 1 minute
  • Spatial resolution: 3×3 km² (mid-latitude)
  • Automatic detection of indoor/outdoor accuracy: > 84 % (R²)
  • Geographic coverage: worldwide (from -66° to +66° latitude)
