Eleanor Wood's winning design features a built-in air filter and fans, powered sustainably by solar panels and a dynamo. The goal of the 12-year-old's design is to filter polluted air, helping the eight million people in the UK who suffer the often-crippling effects of asthma.

Wood entered the 'Backpack To The Future competition' after her mother, who suffers from asthma, put the application form in her room, where she eventually drew up her winning design. She named it the 'Breathe Better Backpack'. 

“I was really shocked when I found out I’d won," Wood said. "I thought of my backpack to help clean the air because some of my family and friends have asthma and hayfever and it could help them.

"I’m very happy the judges chose my entry as the winner. I think it’s a great idea to have cleaner air anywhere you like!”
