Japanese lingerie brand has unveiled a 'smart bra' that claims to 'know how women truly feel', remaining locked until its wearer falls in love.

The stakes are getting increasingly high in the battle for the weirdest piece of wearable tech. After wifi-detecting hats and smartphone-charging wellies, it was only a matter of time until it all turned to sex - with the arrival of vibrating knickers, dresses that turn transparent, and a Google Glass app that lets you imagine you're having sex with yourself.

When we fall in love, we experience an instant boost in excitement," says the company's in-house Human Sexuality Specialist in the promotional video. "That feeling is unlike any other excitement we encounter in life."

"Until now, the bra was a just piece of clothing to remove," says the smart-bra's creator, "but now it is an instrument to test for true love ... destined to become a friend of women around the world."
