Advanced Materials Technologies, EarlyView.In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

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 ...
