SmartHEAL sensor tells you if wound may be infected using RFID

The SmartHEAL sensor was designed by Ph.D. students from Warsaw University of Technology and it is able to measure the pH balance of a wound without having to open the bandage or dressing.

It has an electronic pH sensor that is printed onto a bandage-like textile backing. It uses radio frequency identification or RFID to give you the data that you need. All you have to do is use a mobile device and pass it over the sensor and it can tell you if the pH levels are still okay or if it’s in danger of giving you an infection.
