If you want to see if the person you're dealing with recently is your real one, you might as well try Japan's latest smart bra. When you meet someone you love, it will automatically unlock!
The bra will lock automatically after wearing. The bra has a built-in sensor, which can measure the heart rate. After that, the sensor will send the data to the relevant application in the mobile phone through Bluetooth. The program will analyze and calculate the 'true love rate' according to the heart rate in the past period of time.
If the hostess meets the right man and her heart rate reaches a certain level, the bra will be unlocked. The bra is also the world's first women's underwear equipped with scientific instruments.
