A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition

open access: yesAdvanced 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.

Ultra‐Efficient Kidney Stone Fragment Removal via Spinner‐Induced Synergistic Circulation and Spiral Flow

open access: yesAdvanced Intelligent Systems, EarlyView.
Leveraging spinning‐induced localized suction, the spinner device enables ultra‐efficient removal of kidney stone fragments, capturing a larger quantity of fragments from distances exceeding 20 mm. The spinner significantly improves the efficiency and effectiveness of stone fragment removal by reducing operative time, increasing stone‐free rates, and ...

A Miniature Rotary Electrostatic Clutch for Assigning Multi‐Degrees of Freedom to Insect‐Scale Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.
