7: Perfect Sense • a wearable air quality sensor

Problem:

Some routes taken by schoolchildren to and from their schools are more polluted than others.

Solution:

In April 2020, Ava Garside, 13-years’ old, in Year 9 at the Allerton Grange School, Leeds, England created a graphene-based, wearable air quality pin-badge sensor which collects data and detects the air quality of wherever you are, helping to detect the cleanest and healthiest routes to work or school.

For her “Perfect Sense solution”, Ava was named the Junior winner of the Youth Industrial Strategy Competition, a national STEM – Science, Technology, Engineering and Maths (STEM) initiative coordinated by the government of the United Kingdom and the British Science Association.

She was also awarded the UK Space Agency SatelLife competition. She has since been working alongside scientists at the University of Manchester to develop the prototype further, but like many of the solutions presented on this website, the COVID-19 pandemic has slowed things up.
