Smart mattress will out your lying, cheating spouse - Researchers in China introduce Jia Jia, the 'robot goddess'

If you suspect that your significant other is bringing others into your bedroom, you could have an adult conversation about it or seek couple's counseling. Alternatively, you can buy a 1,700 smart mattress called the Smarttress that will tell you when your partner is having sex with someone that isn't you. Smarttress is the invention of Durmet, a Spanish mattress company that was inspired by the fact that Madrid has the highest number of cheating spouses in Europe. It features 24 sensors within the springs, which the company calls the "Lover Detection System." These sensors know which areas of the mattress are receiving pressure and make a 3D map of the bed.
