It looks like Microsoft's stress-detecting bra won't win the most ridiculous bra award after all.
According to BuzzFeed's excellent breakdown of the bra, it was invented to save women from skeevy guys who are only after one thing (or arguably, two things).
Apparently, this bra is cleverer than your own brain because "it knows how women truly feel". (Although here's a secret guys: women do have sex with men they aren't in love with).
How does it work? According to the product designer, "A built in sensor reads the woman’s heart-rate signal and sends it to a special app via Bluetooth for analysis.”
The 'science' behind the bra
Once the bra exceeds the 'True Love Rate' it then unhooks automatically. This may be inconvenient if you're meeting your other half's parents for the first time or making an important presentation at work.
So to sum up - you could wear this bra to tell who you're in love with and who you aren't. Or you could use that vastly superior organ that doesn't look like it got a D in a GCSE science and technology project: your brain.
