Teen develops bandage which doesn’t need to be changed

The student has developed a sensor for bandages that will update doctors about moisture level without having to remove the dressings


An Oregan seventh-grader’s innovation of bandage with a sensor was placed in top eight in Google’s International Science Contest and it even won the Lego Education Builder Award.

Naiknawa developed a sensor for bandages that will update the doctor about moisture level without having to remove the dressings. Checking bandages too often can actually be detrimental to healing.

“Large wounds need to be kept moist to promote healing, but changing bandages too often to check or ensure moisture levels can make wounds worse,” Naiknawa said.

The key to her bandage sensor is embedding nanoparticles of graphene, which has been noted for its ability to block moisture. When wounds take longer to heal, according to the Google Science Fair, the patients are “susceptible to recurring infections and pain for unnecessarily long periods.”

As an extra point for doctors to look better at wounds, Google says, the teen’s sensor design is cheap to build and biocompatible (not harmful to living tissue).

Naiknawa believes her idea can help people suffering from chronic wounds heal faster and they can get back to routine living life.

According to the Oregonian, when the sensor worked for the first time, Anushka told the publication, “My idea became a physical, tangible reality.”

According to Google the 13-year-old, who loves chemistry, is inspired by Marie Curie’s work to advance modern medicine. In her biography on science fair’s website, she mentions that she also loves to read and figure skate, and plans to get into a top graduate school.

Other finalists in the international science fair did projects on everything from detecting cancers to making rockets more efficient to powering cars with alternative energy. The grand prize winner, 16-year-old South African Kiara Nirghin, found a way to use fruit to retain water in soil and help crops outlast drought.
