The increasing demand for completely self-powered devices, autonomous sensor nodes and solutions to improve the performance of battery-free sensors and transducers has caused an increase of research into smart power harvesting devices and innovative measurement systems. Energy harvesting can be obtained from different energy sources, in particular the attention will be focused on mechanical ambient vibrations (such as naturally noise sources, induced oscillations, vehicle motions, multi tone vibrating systems and noisy environments). A common approach is based on vibrating mechanical bodies that collect energy through the adoption of self-generating materials in order to charge a battery and to supply a specific sensor. This family of systems shows good performance around its natural frequency; however, this is not generally suitable for energy recovery in a wide spectrum of frequencies as it is expected in the vast majority of cases when ambient vibrations assume different forms and the energy is distributed over a wide range of frequencies.
In this context several ways to optimize the amount of harvested energy coming from the environment (i.e. weak kinetic vibrations) will be presented, as regards the conversion, extraction mechanisms and the exploitation of nonlinearities in order to improve the performance of the devices which are able to supply or to sustain a specific sensor or transducer. Particular emphasis will be also given to the exploitation of nonlinear dynamics in autonomous measurement systems able to store the converted energy also in presence of weak level of vibrations, to perform measures of external physical quantities and to transmit data. It is worth noting that the proposed solutions operate passively on ambient vibrations with no required external power or control systems.
Carlo Trigona was born in Italy, in 1981. He received his MS degree in Automation Engineering and Control of Complex Systems and the Ph.D. degree in Electronic, Automation and Control of Complex Systems from University of Catania, Catania, Italy in 2006 and 2009 respectively. From 2010 to 2011, he worked as a post-doc and lecturer at the University Montpellier II – LIRMM (France), from 2011 to 2017 as post-doc and lecturer at DIEEI, University of Catania (Italy) and from 2017 to 2018 he worked as a post doc at the Chemnitz University of Technology (Germany).
Currently he is an Assistant Professor of Electronic Instrumentation and Measurements at the University of Catania (Italy). On March 2017 he received the National Scientific Habilitation to be Associate Professor. Regarding his research activity, the first paper of Dr. Trigona appears in 1997 and, at the moment, he is co-author of more than 130 scientific publications (h index of 17), which include chapters in books, papers in international journals, proceedings of international conferences and patents. His research interests include sensors, transducers, microsystems and microsensors, fluxgate magnetometers and energy harvesting.
