mong other features, smart phones and other new electronic
objects for internet of things require low consumption
and sensing devices, while larger autonomy is a need from the
user side. While photovoltaic devices are limited to appropriate
outdoor conditions, nanobased thermoelectric and piezoelectric
energy harvesters can operate continuously. Efforts are made to
increase the figure of merit ZT of thermoelectric devices together
with using environmental safe materials. We present such an
alternative, nanocomposite superlattices with SiGe, Ti and Mg
silicides materials. Such artificial materials are engineered
to enhance their thermoelectric properties when appropriate
crystal structure, dimensions and doping levels are chosen.
Another strategy to harvest energy, also taking advantage of
the specific nanoscale properties, is the realization of ZnO
and GaN nanogenerators. Modeling and electromechanical
characterization are realized at the nano and macro scales.
Appropriate engineering of the nanogenerators can lead to large
performances. Nanoswitches can be used to control energy of
part of the IC circuit. Nanostructured devices are also presented
for low energy sensing application. Several prototypes and
applications are shown to demonstrate their potential for future
applications.
