In the market for a high-tech chastity belt for your chest? Look no further than the, True Love Tester Bra, brought to you by Japanese lingerie company Ravijour.

The high-tech undergarment, which is being marketed as a way to "save women" from unwanted sexual advances, can supposedly sense when a woman's emotional state becomes truly amorous, and then -- and only then -- will the clasp of the bra automatically unlock. If love isn't in the cards, we guess you're just forced to wear it forever?

According to a video promo for the True Love Tester, the smart bra contains a hidden sensor, which is synced up via Bluetooth to an app on the owner's phone. The app analyzes heart rate, and when the wearer's heart rate hits a specified point, the bra unhooks on its own. (The "true love" zone is indicated in the chart below, though we remain seriously unconvinced as to its scientific accuracy.)

Beyond the fact that we seriously doubt that the bra can "know how women truly feel," as its advertisement claims, the idea behind the undergarment, which was (surprise, surprise) created by two men, ignores some basic truths about women -- and about sex. First of all, a high-tech bra will never "save" a woman from sexual harassment. Just because one's brassiere isn't being ripped off by an aggressive gentleman, doesn't mean that the wearer isn't experiencing a barrage of other forms of unwanted sexual attention before an evening gets to that point. The "savior" nature of the True Love Tester bra is misguided in the same way that AR Wear's anti-rape underwear was, back in November.

Plus, there are many, many reasons that a woman might want to have sex (or simply take off her bra) that have nothing to do with love, true or otherwise. (Lily of "How I Met Your Mother," actually managed to come up with 49.)
