Hand hygiene is probably the most talked about topic of the last two years with the ongoing pandemic. Regular hand washing and sanitizing have made hands the most attended part of our body. To further help with that, thermal imaging is offered by a portable mini camera that is compatible with any iPhone. This technology uses a forward-looking infrared (FLIR) thermal camera to judge the skin temperature after applying sanitizer.

How does it work?

Thermal imaging can be used to examine the efficacy of the sanitizer application. It gives an idea of coverage and missing spots we might get while applying it. This technology is based on the temperature drop after applying sanitizer due to evaporation. This camera comes with a handy app that makes the whole system fit into an iPhone. 

Hand hygiene Study Highlight

  • The thermal imaging could predict the precise temperature at three different points on the hand of the user (mid-palm, third fingertip, tip of thumb) and four distinct times (before sanitizer application, righter after application, 1 min later, 2 min later).
  • A significant temperature drop was observed uniformly on all parts of the hand after sanitization. 
  • This device can also be used as a tool to predict the right amount of sanitizer one needs. The resulting image of participants with large hands showed that recommended amount was insufficient to even reach their fingertips.
