A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition
Advanced Intelligent Systems, EarlyView.An implantable robotic bladder is presented that can store urine in an origami‐designed enclosure. An inductance sensing principle can monitor and transfer the urine volume in real‐time. It can actively expand based on the amount of urine collected from kidneys and apply on‐demand mechanical compression to assist urination.
