Abstract
Recent technological developments are demanding for self-powered electronic systems that need wireless and portable devices. In this regard, nonlinear mechanical energy harvesting systems are proving to be a reliable solution to turn wasted environmental mechanical energy into electrical energy by means of the direct piezoelectric effect. This work addresses a numerical characterization of two mechanical energy harvesting systems investigated based on nonlinear dynamics perspective. Results show complex dynamical patterns and highlight the best application scenario for each harvester.
