A Special Issue on Micro and Nano Fabrication Technology in Renewable Source for Low-Power Portable, Wearable and Autonomous Devices-Part III

摘要

The power generation using "Micro and Nano technology in renewable source" is the novel technique and in this perspective, the possibility of recovering energy from alternative sources and using it to extend the autonomy of such devices or to definitively remove the need for portable but not reusable energy sources such as batteries, constitutes a considerable step forward in terms of reducing dimensions and weight, but also eventually leads to no more need for periodic maintenance. Recent studies in this field already identified the most suitable alternative energy sources in this sense, like electromagnetic fields, mainly emitted in urban environments by telecommunications broadcasting systems, but also vibrational sources, temperature gradients, biochemical sources and so on. The challenges associated with the development of a Micro and Nano technology electronic system dedicated to gather energy and convert it into usable electric power mainly concern the transformation of this energy, passing from the physical domain of origin to an electronic domain.
