Just when you think you’ve seen every kind of wearable there is to see, the D Free comes along in all it its urinary glory. The little plastic sensor attaches to your belly, with a little gel and some medical tape.
Once attached, the system uses ultrasound to determine how full your bladder is. It then sends that information wirelessly to a connected smartphone, showing you the capacity on a scale of 1 to 10.
So, why, precisely would one need that information, when our bodies are fine-tuned to, uh, let us know when it’s time to go? Well, I’m glad you asked, dear reader.
The device is targeted at elderly users who have might have some trouble knowing when to head to the restroom. Everyone’s bladder is different, of course, so so may want to head things off at the pass when the number gets to around five or six on the scale. The battery should get a full 24 four hours after a four hour charge.
The D Free is available now, but it’s pretty pricey. The system costs $40 a month to rent, or you can go ahead and buy it outright for $500. A small price to pay, perhaps, for knowing when it’s time to go.
