Research Progress on Peptide-Based Piezoelectric Carrier Materials

Peptide-based piezoelectric carrier materials demonstrate unique advantages in biocompatibility, tunability, and self-assembly capabilities, making them highly promising for applications in sensors, energy harvesting, and bioelectronics. This paper reviews the research progress of peptide-based piezoelectric carrier materials, starting with an introduction to the basic principles of piezoelectric materials and the application of peptides in material science, with a focus on the mechanisms of peptide integration with piezoelectric materials. The paper then analyzes the current main research directions, including peptide-inorganic material composite systems, peptide-organic material composite systems, and peptide-nanomaterial composite systems, summarizing the characteristics, performance optimization strategies, and potential applications of each type of system. Finally, this paper discusses the challenges faced in the current research on peptide-based piezoelectric carrier materials, such as material stability, controllability, and scalability issues, and looks forward to future research directions, including improving material stability, optimizing peptide sequence design, and exploring their application prospects in new smart materials.
