Condoms That Change Colour When They Detect A Sexually Transmitted Infection

We're always looking for ways to help stay safe, especially when it comes to sex and sexually transmitted infections.

So when a group of teenagers from the UK developed a condom concept that could help save your life, we were all for it.

According to a report on, the condoms work by changing colour when they come into contact with sexually transmitted infections. Each condom, which have been named S.T.Eye, has a built-in indicator to detect infections such as chlamydia and syphilis by turning a different colour when it detects a strain of bacteria.

The 13 and 14-year-old students from Issac Newton Acadaemy in Essex - Daanyaal Ali, Muaz Nawaz, and Chirag Shah - came up with the idea because they were interested in dicovering a way to make detecting STI's safer and more effective than ever before, while eliminating the need for an invasive test.

Daanyall said they created the S.T. EYE to help future generations.
“We wanted to make something that makes detecting harmful STIs safer than ever before, so that people can take immediate action in the privacy of their own homes without the invasive procedures at the doctors,” she said.

“We’ve made sure we’re able to give peace of mind to users and make sure people can be even more responsible than ever before.”

The group received about $2041 (£1000) and a trip to Buckingham Palace.

“We encourage students to take their ideas out of the classroom by putting them face-to-face with industry professionals, helping to open their eyes to the real potential of their ideas,” TeenTech’s founder and chief executive Maggie Philbin said.
