All the single ladies take note: the modern-day chastity belt has finally arrived in the form of a bra.

That’s right. Japanese scientists with a lot of time on their hands have created a bra that only unhooks when your heart rate reaches a certain level.

The ‘True Love Tester’ will measure a woman’s heart rate to determine if she is sexually interested in her partner and it’s only when the woman hits the ‘Heart Rate of Love’ that the bra can be unhooked.

In a sexually explicit ad for the bizarre product, a ‘human sexuality expert’ explains that “when women fall in love they experience an instant boost in excitement. That feeling is unlike another other excitement we encounter in life.”

At this stage the bra is not for sale and is only being road-tested on a select few couples in Japan, which is bad news for guys looking for a particularly frustrating Valentine’s Day present.
