New wearable device could help people with spinal injuries know when to empty their bladder

This study tests a wearable microwave sensor that monitors bladder fullness without needles or catheters. About 40 adults with spinal cord injury who use self-catheterization will wear the sensor while their bladder fills and empties. The goal is to see if the device can accurately tell when the bladder is full, helping people manage their bladder more easily and comfortably.
