Uri-Go, wearable technology that alerts you to how full your bladder is, has won New Zealand’s major tech award, the C-Prize. Worn as a belt, this Bluetooth-enabled product’s measuring device is roughly the size of a business card and sits just above your pubic bone inside your underwear. When its time to pee, it notifies you via your smart phone.

Uri-Go was dreamed up by inventor and paraplegic Mike Brown, who partnered with urologist Dr. Frank Kueppers and tech product engineer Brendon Hale to develop the product.
