12.1 Introduction
In the preceding chapters, various hierarchical nanostructures for energy
ecient electronics applications among energy devices have been discussed.
Electronics are the final stage for energy cycles and basically consume energy
that was generated by energy harvesting devices and energy storage devices.
Among the biggest electronics using nanostructures are displays (Chapter
10) and sensors (Chapter 11). Additionally, the application of hierarchical
nanostructures can be found in various research topics: (1) highly ecient
energy consumption devices including transparent conductors, highly
flexible and stretchable electrodes, light emitting diodes, and (2) mechanical
hierarchical nanostructures, for example, for super-hydrophobic and self-
cleaning surfaces, pool boiling enhancement for more ecient heat transfer,
and gecko-inspired adhesives. As long as the surface area or surface
characteristics are considered an important factor to enhance the
functionality of the devices, applying hierarchical nanostructures is one of
the most powerful and promising approaches with a very high degree of
design freedom.
In this chapter, other research trends for hierarchical nanostructures for
highly e cient energy consumption devices other than the electrical devices
discussed in the previous chapters and mechanical devices will be
