Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly

, attributed to strong asymmetric molecular packing, confirmed by microcrystal electron diffraction (MicroED) and density functional theory (DFT) analysis. Nanogenerators based on these crystals achieve an open-circuit voltage of 2.57 V under 50 N, the highest among short peptides in aqueous environments. These findings advance peptide crystal engineering and highlight their potential for high-performance piezoelectric devices.
