Summary: | Peptide assemblies have attracted significant attention due to their high piezoelectric performance and biocompatibility. However, since piezoelectricity is an orientation‐dependent property, the alignment of these structures presents a major challenge for their use in piezoelectric applications. We recently showed an ultra‐aromatic peptide derivative termed Boc−Dip−Dip to exhibit notably high piezoelectric properties. Here, by obtaining an aligned Boc−Dip−Dip array, we were able to realize the potential of the peptide to form an active piezoelectric layer. The voltage coefficient of the piezoelectric layer calculated using an in‐house measurement set‐up was more than 2‐fold higher compared to poled polyvinylidene−fluoride, the gold standard for piezoelectric biocompatible materials. Our findings pave the way for the utilization of novel piezoelectric biomaterials, bearing the potential to replace lead‐based toxic piezoelectric materials, especially in the field of bio‐application. |
