The ‘True Love Tester’ has built in sensors to monitor the wearer’s heartbeat and remains locked until a heart rate of genuine excitement is reached.
Japanese lingerie maker Ravijour designed the device with a clasp that automatically springs open if a rate of ‘true love’ is detected by a sensor. The bra then sends the message over Bluetooth to be analysed by an app.
Ravijour explained: “When excited, the adrenal medulla [gland] secretes catecholamine, which affects the automatic nerve, and stimulates the heart rate. A sensor reads the woman’s heart rate and sends it to a special app via Bluetooth for analysis.”
They continued: “The app then calculates the True Love Rate based on changes in the heart rate over time. When the True Love Rate exceeds a certain value, the bra hook is opened.”
The bra is yet to become available to the public but is being offered as top prize in a competition held to celebrate Ravijour’s tenth anniversary.
