SPRINGERBRIEFS IN MATERIALS NANOSTRUCTURED PI...

This book covers a range of devices that use piezoelectricity to convert mechanical deformation
into electrical energy and relates their output capabilities to a range of potential
applications. Starting with a description of the fundamental principles and properties of
piezo- and ferroelectric materials  where applications of bulk materials are well established 
the book shows how nanostructures of these materials are being developed for energy harvesting
applications. The authors show how a nanostructured device can be produced  and put in context
some of the approaches that are being investigated for the development of nanostructured
piezoelectric energy harvesting devices  also known as nanogenerators. There is growing
interest in strategies for energy harvesting that use a variety of existing and well-known
materials in new morphologies or architectures. A key change of morphology to enable new
functionality is the nanostructuring of a material. One area of particular interest is
self-powered devices based on portable energy harvesting. The charging of personal electronic
equipment and other small-scale electronic devices such as sensors is a highly demanding
environment that requires innovative solutions. The output of these so-called nanogenerators is
explained in terms of the requirements for self-powered applications. The authors summarise the
range of production methods used for nanostructured devices  which require much lower energy
inputs than those used for bulk systems  making them more environmentally friendly and also
compatible with a wide range of substrate materials.
