The objective of this proposal is the development of novel concepts for energy harvesting, which combine soft dielectric elastomer (DE) generators with bi-stable mechanisms and software intelligence. These novel systems will overcome the limitations of state-of-the-art mechanical energy harvesters in an unprecedented way, by enabling high conversion rates from broadband sources concentrated in the low-frequency range (0.1-10 Hz). This will open up new perspectives for renewable energy conversion from the environmental sources, such as ocean waves. In this research project, we will address all the steps which are needed to enable for the first time bi-stable DE generator technology. To achieve this goal, the PI Jun.-Prof. Gianluca Rizzello (Saarland University) will develop novel solutions at both hardware and software level, ranging from systematic methods to design, fabricate, and characterize bi-stable DE generators, up to optimal energy extraction policies based on self-sensing control algorithms. Prof. Giacomo Moretti (University of Trento, IT), who is a renowned expert in the field of DE generators, will also provide contributions to concept generation, design, and testing tasks through a Mercator Fellowship.
