“…Piezoelectricity has been found in peptides, including diphenylalanine (FF) [53], cyclo -glycine-tryptophan ( cyclo -GW) [54], β glycine [52], gamma ( γ ) glycine [55], Fmoc-FF [56], cyclo -phenylalanine-tryptophan (FW) [54], and bis-cyclic- β -peptides [57]. Among them, FF peptides were the most studied piezoelectric biomaterials.…”

Piezoelectric materials are important for many physical and electronic devices. Although many piezoelectric ceramics exhibit good piezoelectricity, they often show poor compatibility with biological systems that limits their biomedical applications. Piezoelectric peptide and metabolite materials benefit from their intrinsic biocompatibility, degradability, and convenient biofunctionalization and are promising candidates for biological and medical applications. Herein, we provide an account of the recent progress of research works on piezoelectric peptide and metabolite materials. This review focuses on the growth mechanism of peptide and metabolite micro- and nanomaterials. The influence of self-assembly processes on their piezoelectricity is discussed. Peptide and metabolite materials demonstrate not only outstanding piezoelectric properties but also unique electronic, optical, and physical properties, enabling their applications in nanogenerators, sensors, and optical waveguiding devices.

“…Another point for the coming-era's organic dielectrics is downsizing and the reduction of dimensions under the structural control at nanoscale sizes, which design is essential for highly potent piezoelectric nanomaterials. [8,[10][11][12][13] For example, the piezoelectric coefficient increases upon dimensional reduction to the nanoscale, as reported for nanofibers of poly(vinylidene fluoride trifluoroethylene). [14] The combination of tetrathiafulvalene (TTF) and chloranil is a typical example of the formation of charge-transfer complex, and is a promising candidate for piezoelectric materials based on electron polarization.…”

“…For high‐frequency field applications, however, piezoelectric materials arising from electronic polarizations are advantageous owing to low dielectric losses even in high‐frequency ranges compared with those based on dipolar polarizations. Another point for the coming‐era's organic dielectrics is downsizing and the reduction of dimensions under the structural control at nanoscale sizes, which design is essential for highly potent piezoelectric nanomaterials [8,10–13] .

Tetrathiafulvalene (TTF) and chloranil were introduced at the side chains of different cyclic tripeptides, which were self-assembled into peptide nanotubes (PNTs). PNTs were used as scaffolds for alignment of the charge-transfer complexes between TTF and chloranil, and they were prepared via two methods, one is that mixing a PNT comprising only TTF with a PNT comprising only chloranil (method 1), and the other is that one pot mixing of cyclic tripeptides with TTF and cyclic tripeptides with chloranil to be self-assembled into PNTs (method 2). These PNTs naturally associated to form PNT bundles. The surface potentials of the PNT bundles became larger for the PNTs carrying charge-transfer complexes along the PNT (method 2) than those between PNTs (method 1). This bundle of PNT carrying charge-transfer complexes along the PNT (method 2) showed a hysteresis response in the piezoelectric force curve with varying bias voltages according to piezoelectric force microscope measurements.

“…[1][2][3][4] These phenomena, in turn, enable a wide range of applications from sensing to optoelectronics. [3][4][5][6][7][8][9][10][11][12] The piezoelectric effect (PE) comprises two effects: a direct effect, in which mechanical stress generates an electric charge. Inversely, the converse PE generates a mechanical response to an applied electric field.…”

We report a new methodology for the electromechanical characterization of organic monolayers based on the implementation of dual AC resonance tracking piezo force microscopy (DART-PFM) combined with a sweep of an applied DC field under a fixed AC field. This experimental design allows calibration of the electrostatic component of the tip response and enables the use of low spring constant levers in the measurement. Moreover, the technique is shown to determine both positive and negative piezo response. The successful decoupling of the electrostatic component from the mechanical response will enable more quantitative electromechanical characterization of molecular and biomaterials and should generate new design principles for soft bio-compatible piezoactive materials. To highlight the applicability, our new methodology was used to successfully characterize the piezoelectric coefficient (d<sub>33</sub>) of a variety of piezoactive materials, including self-assembled monolayers made of small molecules (dodecane thiol, mercaptoundecanoic acid) or macromolecules (peptides, peptoids), as well as a variety of inorganic materials, including lead zirconate titanate [PZT], quartz, and periodically poled lithium niobate [PPLN]. Due to high differential capacitance, the soft organic monolayers demonstrated exceedingly large electromechanical response (as high as 250 pm/V) but smaller d<sub>33</sub>piezocoefficients. Finally, we find that the capacitive electrostatic response of the organic monolayers studied are significantly larger than conventional inorganic piezoelectric materials (e.g., PZT, PPLN, quartz), suggesting organic electromechanical materials applications can successfully draw from both piezo and electrostatic responses.
