Abstract

This research explores the creation of a self-assembled, non-toxic, and eco-friendly piezoelectric device using peptide-based materials. The study focuses on molecular engineering of collagen-mimicking peptides to amplify their electromechanical properties and generate technologically relevant piezoelectricity. By using a minimalistic collagen building block, a peptide-based piezoelectric generator was fabricated, demonstrating a significantly higher piezoelectric response than previously observed in short natural peptides, and achieving stable current and voltage outputs.
