At first, the Smart e-Pants may seem like something out of the popular erotic novel, '50 Shades of Grey.' It is a pair of underwear that delivers a low zap of electricity via two pads of electrodes placed on each butt cheek. Without much context, a person can't be blamed for thinking the Smart e-Pants were created for kinky situations. In reality, they were invented to combat bedsores (also known as Pressure Ulcers).
Developed by Project Smart and tested by doctors at the University of Calgary, the Smart e-Pants were created to be worn by those who suffer from spinal cord injuries. During the testing phase, the Smart e-Pants delivered 10 second zaps every 10 minutes for 12 hours a day for a month and none of the patients developed a sore.
