Kimberly-Clark has developed a portable device that alerts the user to instantaneous and accumulated UV exposure based on the ambient UV and the user’s own skin type. Different skin types react to UV exposure differently. The sensor can also advise on sunscreen SPF levels required and application times.  There are many UV sensors and skin sensors available on the market. However, this is the only invention that integrates the two sensors. The device uses both sensors to advise the user.


  • The system tracks and alerts a user about UV radiation based on measurement of skin type.
  • This is the only device that integrates UV sensor, sensor for skin type, and controller.
  • Skin type sensor measures characteristics such as erythema and melanin.
  • The UV detection device measures ultraviolet ray quantity present in the environment.
  • The controller bases its advice on data received from the skin measuring device and the ambient UV, as well as the amount of time the user will be exposed to the environment.


The company seeks to license the device and/or the associated patents and know-how for use as a stand-alone product or to be incorporated into other high-tech wearables and smartphones for the outdoor and fitness market. The wearable sensors market is expected to grow to well over $5.5B USD by 2025.  The technology is in early prototype stage, right for adding as a feature to other devices. Kimberly-Clark is willing to produce samples for parties having serious interest.
