TL;DR: In this paper, the key roles of mechanical modulations for energy harvesting are emphasized, and the methods and principles of mechanical modulation and their applications to energy harvesting systems are reviewed and classified into three categories: excitation type conversions, frequency up-conversions, force/motion amplifications.

TL;DR: In this article, a novel water-proof hybrid wind energy harvester (WP-HWH) using magnetic coupling and force amplification mechanisms was proposed, which can operate effectively in a harsh environment, such as rainfall.

TL;DR: In this paper, a magnetically coupled two-degree-of-freedom vibration energy harvester for rotary motion applications is presented. But the design consists of two inverted piezoelectric cantilever beams whose free ends point to the rotating shaft.

TL;DR: In this paper, a rotational piezoelectric wind energy harvesting using magnetic coupling and force amplification mechanisms was proposed, which has a higher equivalent piezo-lectric coefficient, better robustness and broader wind speed range for application.

TL;DR: A brief overview of the studies published over the past decade on mechanical, acoustic, electromagnetic and thermal energy harvesting using the relevant metamaterials is provided to spark the interest of new investigators to this unconventional but fast-evolving branch of energy harvesting that will impact the Internet of things, smart cities and sustainable developments.
