(L-R) Muaz Nawaz, Daanyaal Ali and Chirag Shah discuss their ST Eye invention. TeenTech Awards TeenTech Awards

A GROUP OF secondary school students in England have invented a condom that changes colour if you have a sexually-transmitted infection (STI).

The three boys, aged between 13 and 14, won a major award in London this week for their work on a condom embedded with molecules that detect the presence of diseases such as chlamydia and herpes, and change a different colour for each one.

14-year-old Daanyaal Ali said the idea was to make STI testing easier and less intimidating:

We created the S.T.EYE as a new way for STI detection to help the future of the next generation.

We wanted to make something that made detecting harmful STIs safer than ever before, so that people can take immediate action in the privacy of their own homes without the often-scary procedures at the doctors.

We’ve made sure we’re able to give peace of mind to users and let people act even more responsibly than ever before.

Ali, along with Muaz Nawaz and Chirag Shah, took home top prize in the Health category at this week’s Teen Tech awards in London.

According to organisers, the students have already been approached by a condom manufacturer, who has expressed an interest in their invention.
