Energy harvesters are self-sustaining systems capable to capture, process, store
and apply small amounts of free energy into the environment. These are
composed by three stages: the micro-generator or source, the voltage booster
or power converter and the storage element. In the case of harvesting
mechanical vibrations the environment, piezoelectric materials have been used
as transducer, the classical is PZT ceramics due to the mechanical coupling
factor however some drawbacks must be addressed in order to integrated into
silicon, not only the harvesting stage but also to embed a power management
electronic circuits. Another approach is the use of silicon nanostructures as
thermoelectric thin film devices. Thus, this work exposes some application
materials to devices for energy harvester with its electronic architecture to
improve the efficiency in a complete system, such as the Maximum Power Point
Tracking (MPPT) circuit.
Keywords: energy harvesting, silicon integration, maximum power point
