A home-testing kit for breast cancer has won this year's international James Dyson Award.
The Blue Box was designed by 23-year-old Judit Giró Benet, from Spain, who will receive £30,000 in prize money.
A second award, for sustainability, went to a product that uses waste crops to convert UV light into renewable energy.
The annual award helps young engineers to develop their inventions.
Ms Benet came up with the idea following her mother's diagnosis of breast cancer. She realised there was a need for a more accessible test for the disease.
Screening requires women to attend hospitals or medical facilities and undergo what can be for some an uncomfortable and costly procedure. As a result, it is estimated that 40% of women skip their regular mammogram, resulting in one in three cases being detected late, leading to a lower chance of survival.
