A smart plaster – level 2

23-11-2022 15:00

Three students from a university in Warsaw, Poland, invented a smart plaster.

The plaster is called SmartHEAL, and has a special sensor which checks the pH in a wound.  When doctors take off a plaster, they risk infection, and they also damage the tissue. The process is very painful and unpleasant for the patient.

Thanks to SmartHEAL, doctors don’t need to take the plaster off, and they know how the wound is healing. This situation is very important with wounds which take months or even years to heal.

The students won an award for the plaster, and they want to use the prize money to start testing SmartHEAL on real patients. They hope that they can start selling the smart plaster in 2025.

Difficult words: pH (a measure of how acidic something is), wound (a cut or hole in the body), tissue (an inside part of the body which has a specific job).
