Smart bandage designed by girl, 13, signals when it needs to be changed

A smart bandage that detects moisture levels and signals when it needs to be changed has helped a seventh grade student impress the judges at the Google Science Fair. Anushka Naiknaware, 13, is a student at Stoller Middle School in Beaverton, Oregon. Her invention finished in the top eight at the competition, according to the event’s official website. Naiknaware won a $15,000 scholarship and a free trip to Lego headquarters in Denmark, with a year of entrepreneurship mentoring from a Lego executive. The bandage uses biopolymer chitosan with carbon nanoparticles to reduce bleeding and measure moisture levels in the wound. A battery and bluetooth chip sit on top of the bandage and are covered by a regular bandage adhesive layer. When the moisture level is high, the electrons inside the bandage experience less resistance; when the bandage dries up, the electrons detect much higher resistance. The change in resistance is noted and can be wirelessly transmitted to a mobile device, which then prompts the user to change bandages. ---------------------------------------­­---------------------------------------­-­--------------- Next Animation Studio’s News Direct service provides daily, high-quality, informative 3D news animations that fill in for missing footage and help viewers understand breaking news stories or in-depth features on science, technology, and health.
