Water‐Stable, Biodegradable, and Flexible Glycine‐Based Piezoelectrics via Multi‐Length‐Scale Composite Engineering
Biomolecular piezoelectrics offer promising alternatives to ceramics for transient electronics and medical devices due to their intrinsic biocompatibility and biodegradability. Among them, β‐glycine exhibits high piezoelectricity, but its practical applications are severely limited by its inherent rigidity and its ra...
