“…The acoustic sensor based on butterfly wings has a linear relation between acoustic pressure and output voltage amplitude and relatively flat frequency response. [ 29 ] Tests on samples from different butterflies (of the same species) have also shown the relative repeatability of the acoustic sensors based on butterfly wings. The selective optical sensitivity in the blue‐light wavelength range indicates that the sensing performance can be further improved if blue light sources are used.…”

In recent years, there has been an increasing interest in the novel bioinspired sensors, especially for their selectivity, response time, and sensitivity. Particular attention is paid to the novel optical functional materials that are crucial for the sensors to achieve various energy transduction. Ideally, many critical parameters of the optical sensing materials can be appropriately tailored to meet various specific requirements using optimal design. Over a long and cruel evolution, nature's creatures have created a variety of photonic structures. One impressive example is the iridescent wings of butterfly. The natural photonic crystals on its surfaces have inspired diverse novel designs of optical functional sensing materials, especially in the past three years. Herein, this review mainly discusses recent advances of the burgeoning butterfly‐inspired sensing materials with optical properties that can be modulated in response to different external stimuli. First, their optical sensing performance to infrared radiation/thermal, vapor, liquid, pH, and so on are discussed in details. Then, the fabrication methods and their working mechanisms are also introduced. Furthermore, the general strategies of these emerging sensing materials and their potential applications are also discussed in‐depth as well as their limitations and the future challenges.

“…The surfaces of its wing scales possess highly anisotropic topological structures that have been shown to be applicable in photonic devices, molecular sensors, and self-cleaning surfaces. [18][19][20][21][22] In particular, the parallel ridges of the wing scale have been used as a natural 3D scaffold for orienting cellular growth. Although the M. Menelaus wing has exhibited advantages in biomedical fields and has seen much progress in it applications, its potential as a composite conductive material with 3D hierarchical structures has not been well explored.…”

their advantages in functional integration, biomedical engineering materials have been used to facilitate nerve regeneration and to regulate neural behaviors through the use of nerve guidance conduits, [3][4][5] bioactive molecule patterning, [6][7][8][9][10] conductive elements, [11][12][13] and so on. Among these, topographical conductive surfaces have the potential to induce neuron orientation, and functional materials possessing such surfaces have aroused extensive attention. [14,15] As one such material, superaligned carbon-nanotube sheets (SA-CNTs) have excellent electrical conductivity and mechanical properties and thus have been employed in neurobiological studies such as electrophysiological maturation, [16] growth behavior regulation, and nerve regeneration. [17] However, despite the progress made in the application of SA-CNTs, these materials only influence the cultured cells by their aligned direction, and this may limit their efficiency in inducing oriented cell growth due to the difference between the nanometer scale of SA-CNTs and the micrometer scale of cells. In addition, because of the lack of 3D topological structures, these SA-CNTs make it difficult to simulate the extracellular matrix in neural tissues. Therefore, topographical conductive materials with 3D structures and cellular orientation capabilities are still sought. Spiral ganglion neuron (SGN) degeneration canlead to severe hearing loss, and the directional regeneration of SGNs has shown great potential for improving the efficacy of auditory therapy. Here, a novel 3D conductive microstructure with surface topologies is presented by integrating superaligned carbon-nanotube sheets (SA-CNTs) onto Morpho Menelaus butterfly wings for SGN culture. The parallel groove-like topological structures of M. Menelaus wings induce the cultured cells to grow along the direction of its ridges. The excellent conductivity of SA-CNTs significantly improves the efficiency of cellular information conduction. When integrating the SA-CNTs with M. Menelaus wings, the SA-CNTs are aligned in parallel with the M. Menelaus ridges, which further strengthens the consistency of the surface topography in the composite substrate. The SA-CNTs integrated onto butterfly wings provide powerful physical signals and regulate the behavior of SGNs, including cell survival, adhesion, neurite outgrowth, and synapse formation. These features indicate the possibility of directed regeneration after auditory nerve injury.

Examples include the modulation of the optical and electrical properties of grapheme, 15,16 the magnetization of ferromagnetic thin films, 17 the generation of a photoflexoelectric effect in halide perovskites solar cells, 18 and the induction of lens focusing effects for the rheological analysis of tiny volumes of liquids. 19 Surface propagating SAWs, have been also used for the processing of nanomaterials in liquid media through the deposition of organic thin films 20 or the patterning of nanowires, 21 nanoparticles 22 or carbon nanotubes.…”
