A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress
Advanced Materials Technologies, EarlyView.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 ...

Pulsating Heat Pipe Simulations: Impact of PHP Orientation [PDF]
, 2019 The pulsating (called also oscillating) heat pipe (PHP) is a simple capillary tube bent in meander and filled with a two-phase fluid. We discuss numerical simulations of the 10-turn copper-water PHP under vertical favorable (bottom-heated), vertical unfavorable (top-heated), and horizontal orientations.
