Biological structures such as amino acids, peptides, and proteins are emerging as promising candidates for piezoelectric energy harvesting and sensing. Here we highlight the position of biological materials in the diverse world of piezoelectric structures, and emphasise how a nanoscale insight into these assemblies, particularly in crystalline form, can pave the way for development of a diverse new array of biocompatible sensors for a greener future. By harnessing advances in high performance computing, we can begin to screen the vast library of biomolecules for optimum candidates, with the ultimate goal of re-engineering biological piezoelectricity by first principles design.
