In a perfect world, women would not have to deal with violence against them. Unfortunately, rape is a serious issue in our world today. We have seen plenty of anti-rape and anti-violence gadgets for women in the past. The True Love Tester Bra is one that can’t be undone without love. It has a sensor that reads a woman’s heart rate signal and uses an app to analyze that data. The bra unlocks automatically if its app detects true love. Not sure how accurate this is but the idea is interesting.
