DHAKA: In a long-awaited fusion between hot-blooded hormones and cold-headed engineering, a Japanese lingerie company has produced a bra they claim will only unlock when the wearer is really in love.

The ‘True Love Tester’ uses sensors and a special gadget linked to a mobile device to analyse the pattern and speed of the user’s heart beat in the heat of the moment.

If the app determines the woman’s feelings are for real, the clasp at the front pops open to allow matters between lovers to take their course.

The bra is a gimmick by lingerie brand Ravijour, which says it is not for sale, but forms part of a publicity campaign for the marque’s 10th anniversary, reports The Straits Times.
