Meet Dfree: a smart wearable device that predicts when you need to visit the bathroom. It uses ultrasonic waves to monitor your internal organs and sends the data to your smartphone. As explained by Triple W Japan, the device targets users who suffer from incontinence. It fits on the user’s underwear to get the job done.
As the developers explain, the device needs to be tweaked a bit more before it is ready to be released. Reuters has the story.
