A wearable device that reminds you when you need to go to the toilet might sound like a joke. But when you consider that the young, the old, the sick and the pregnant can all have difficulties in working out when they need to go, then D Free, from Japanese company Triple W, makes a lot of sense.
The device sits on your stomach and uses ultrasonic waves to monitor your internal organs. When it works out that the user needs to answer nature’s call, it will send an alert to your phone.
The only problem, according to Wearable Insider, is how to attach the device, with sticking tape apparently having considerable drawbacks, particularly for the young and the old.
