A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress
This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...
