Smart Products Sell Because People Are Stupid

Consumers are buying personal care products with built-in smart technology because people are dumb. Procter & Gamble's Oral B Genius 9000 toothbrush comes with technology that tells the user whether he is brushing his teeth properly and what the weather is like outside. For people who love working out, the Elvie pelvic floor contraption functions as a personal trainer. Unilever is testing its Peggy smart clothes peg, which includes a built-in thermometer and hygrometer, in Australia. For women, there is the smart tampon, which is attached to a wire that connects to a sensor clipped to the underwear. This tampon alerts the user's phone whenever it is time for a new one.
