Structural colors originate in the scattering of light from ordered microstructures, thin films, and even irregular arrays of electrically small particles, but they are not produced by pigments. Examples include the flashing sparks of colors in opals and the brilliant hues of some butterflies such as Morpho rhetenor. Structural colors can be implemented industrially to produce structurally colored paints, fabrics, cosmetics, and sensors.

Insects are dependent on the spatial, spectral, and temporal distributions of light in the environment for flight control and navigation. This chapter reports on flight trials of implementations of insect-inspired behaviors on unmanned aerial vehicles. Optical-flow methods for maintaining a constant height above ground and a constant course have been demonstrated to provide navigational capabilities that are impossible using conventional avionics sensors. Precision control of height above ground and ground course were achieved over long distances. Other demonstrated vision-based techniques include a biomimetic stabilization sensor that uses the ultraviolet and green bands of the spectrum and a sky polarization compass. Both of these sensors were tested over long trajectories in different directions, in each case showing performance similar to low-cost inertial heading and attitude systems.

In a sense, the archetype of bioinspiration for materials design and use is textiles. The field of biomimesis has spawned many new materials and continues to be a fruitful field of investigation. This chapter presents the current state of bioinspiration in textiles, how this has resulted in improved fibrous materials, how it may inform our continued progress. Because I have found many preconceived notions about the field that need addressing before the application of biomimetics to textiles can be truly appreciated, I begin with an introduction to textiles. Next, naturally enough, the discipline of biomimesis is introduced and then fleshed out in terms of its textile engineering importance. Following this, some details on fiber and textile science and engineering are discussed and biological concepts germane to our topic are presented. In the last step in this journey, the marriage of biomimesis and textiles is performed and some consequences revealed. Finally, I offer some prognostications on the topic.

Self-organization and self-healing appeal to humans because difficult and repeated actions can be avoided through automation via bottom-up nonhierarchical processes. This is in contrast to the top-level controlled manner we normally apply as an action strategy in manufacturing and maintenance work. This chapter presents eight different self-organizing and self-healing approaches in nature and takes a look at realized and potential applications. Furthermore, the core principles for each approach are described using simplified drawings in order to make the ideas behind the self-organizing and self-healing principles more accessible to design practitioners.

The compound eyes of moths are composed by hexagonal arrays of non-close-packed nipples that exhibit low reflectance. The outer surface of the cornea of a moth consists of periodic arrays of conical protuberances, termed corneal nipples, typically of sub-250nm height and spacing. These arrays of subwavelength nipples generate a graded transition of refractive index, leading to minimized reflection over a broad range of wavelengths and angles of incidence. In this chapter, the fabrication, characterization, and modeling of moth-eye antireflection coatings on both transparent substrates (e.g., glass) and semiconductor wafers (such as crystalline silicon and GaAs) are discussed.

The principal motivation behind surface engineering and modification for improved biocompatibility of a biomaterial is to control interactions of the biomaterial with components of living systems or subsets thereof in a manner that mimics the normal physiological state or produces a desired change in biological state. This pursuit of biomimicry is discussed in this chapter within the context of the core mechanisms of the biological response to materials. A tutorial on surfaces, interfaces, and interphases leads to the identification of specific targets for surface engineering and modification. These targets include water wettability (surface energy), surface chemistry, surface chemical patterns and surface textures, and surface presentation of biomimetic motifs. The chapter concludes with a discussion of the essential conceptual tools required for building a biomaterials surface science laboratory, illustrated with an example of modifying surfaces for improved cardiovascular biomaterials.

Some basic features of biomimetic robotics and the technologies that are facilitating their development are discussed in this chapter. The emergence of smart materials and structures, smart sensors and actuators capable of mimicking biological transducers, bio-inspired signal-processing techniques, modeling and control of manipulators resembling biological limbs, and the shape control of flexible systems are the primary areas in which recent technological advances have taken place. Some key applications of these technological developments in the design of morphing airfoils, modeling and control of anthropomorphic manipulators and muscle activation modeling, and control for human limb prosthetic and orthotic applications are discussed. Also discussed, with some typical examples, are the related developments in the application of nonlinear optimal control and estimation, which are fundamental to the success of biomimetic robotics.

Biomimicry offers innovative sustainable solutions for many dire resource-based challenges. The Namib Desert beetle (sp. Stenocara) invites us to explore how we can collect fresh water more energy-efficiently. The beetle's unique back features with alternating hydrophobic-hydrophilic regions, aid its survival in a water scarce desert environment. We investigated the feasibility for enhanced condensation by patterning a zinc oxide (ZnO) surface to mimic the beetle's back. ZnO was selected as the material of choice given its non-toxicity and photoinduced hydrophilicity capability, combined with the ability to fabricate (super)hydrophobic ZnO surfaces with various thin film fabrication techniques. The key innovation in our approach is developing a chemically homogeneous, non-insulating film on a metal substrate (practical engineering heat transfer material) that exhibits a hydrophobic-hydrophilic pattern. We successfully developed and implemented a scalable and practical technique to satisfy our main objective. Hydrophobic ZnO thin films were fabricated by electrodeposition on copper substrates and patterned with UV exposure to have both hydrophobic and hydrophilic regions. Even though statically the ZnO films were hydrophobic, they exhibited filmwise condensation instead of the more efficient dropwise condensation mode. This is attributed to the ZnO films being in a metastable Cassie-Baxter mode that transitioned to the wetting Wenzel mode during the dynamic and transient condensation state.
