About this Research Topic
The integration of energy harvesting solutions based on smart materials or nonlinear structures is still challenging for both academic and industrial research communities. The goal is usually to power harvested systems from the ambient environment through the design of self-powered devices without batteries or by using rechargeable ones. Recent improvements have revealed interesting possibilities to drive advances in energy harvesting systems, including several methods to harvest energy from the environment: electrostatic, piezoelectric, electromagnetic, magnetoelectric, triboelectric, thermoelectric, pyroelectric, photovoltaic, etc. In particular, the investigation of such systems through simulation, modelling and experiments for nonlinear structures including bistability, stochastic behavior and/or nonlinear spring is of high importance.
This Research Topic aims to identify energy harvesting solutions that enhance the performance and gains in terms of reliability, flexibility and efficiency. It focuses on the innovative developments, technologies, and challenges related to energy harvesting systems, including modeling, characterizations of materials and nonlinear structures, as well as a practical use case of energy harvesting in real applications related to industrial, medical and health monitoring fields. Furthermore, the development of new smart materials is of concern to improve the harvester's performance enabling its miniaturization and hybridization. This research also addresses numerical and experimental investigations for innovative energy harvesting systems developed for specific applications covering industry, automotive, medical field and structural health monitoring considering environmental conditions and challenges.
