The Introduction of the Special Issue

Providing a green, virtually infinite alternative power source to traditional energy sources will significantly expand applications for WSNs and other technologies. The use of piezoelectric materials to capitalize on the ambient vibrations surrounding a system is one method that has seen a dramatic rise in the use for power harvesting. Most of the works found in literature are different in their structures and vibration frequencies, and only few of them have focused on power harvesting under both low frequency and acceleration applications.

The present situation in Asia and in the world obviously represents a challenge to our ability for rethinking the energy producing systems, not only due to the new conscience spreading in our minds that the resources in which we have relied for a century are in reality finite, but also due to the fact that the creation of energy is since those times strongly based on destructive processes. That is, the energy is obtained from sources that must be constantly destroyed, with a significant part of the results transformed into waste, which is extremely aggressive both for our health and the equilibrium of the surrounding nature. This special issue for Insight-Energy  Science journal shows the state of the art for the designed and published harvesters, indicated  that the overall harvested power is not to be applicable.The published work in this issue will have the intention to contribute to the development of these ideals, knowing that systems of several types and configurations are being tested and studied in many institutions, and old concepts improved in efficiency, but that new principles of operation are obviously not so frequent.

The work that will proposed in this issue of our journal acts as major objective of the development and the test of a new principle to retrieve electrical energy from the surrounding ambient vibrations. This principle is based on a complete and closed circle of energy transfer,therefore creating no waste. Another interesting feature of it is, that there is strong evidence that probably it will allow the  design of piezoelectric harvesters from the micro-metric or even nano-metric dimensions, depending on the technology used. The main objectives of this special issue of the Insight-Energy science journal are to develop, validate a model, and simulate a new structure of cantilever-based MEMS piezoelectric energy harvester and investigate its ability to harvest and optimize electrical power.

 The work performed to achieve these objectives includes:

1. Selecting a suitable theoretical model for a cantilever-based piezoelectric energy harvester,based on the assumption that the system is linear, in order to predict the mechanical and electrical responses of the harvester.

2.Carrying out experiments to test a basic standard structure fabricated sample of a macroscaled energy harvester and comparing their experimental measurements to theoretical results to validate the theoretical model.

3. Simulating and comparing a various standard cantilever structures of the energy harvester operating in the low frequency application to understand how the self-power is generated due to an ambient vibration surrounding the harvester.

4. Modeling, design, simulation and model verification of a broadband arrayed MEMS
