Recent studies on biomolecular piezoelectric crystals such as self-assembled amino acids, peptides, proteins, and viruses have great attention because they are applicable to bioelectronics and biomedical applications. Especially, diphenylalanine (FF) and M13 bacteriophage has been reported to exhibit strong piezoresponse comparable to conventional piezoelectric materials. However, the difficulty of fabricating scalable unidirectionally polarized structures that can convert mechanical force into electricity has been a major obstacle to the realization of a strong piezoelectric energy generators. In this talk, I will present a strategy to synthesize large-scale aligned biomolecular piezoelectric materials that is FF nanotubes and M13 bacteriophage. The polarization direction of these materials was controlled using self-assembly process. Furthermore, the biological piezoelectric materials based piezoelectric energy generators were demonstrated. |
