20 EMR 15 Lille June 2015 Summer School EMR 15 Energetic Macroscopic Representation A piezoelectric Energy Haresting Deice is a system, and needs a systemic approach, A strategy can be used in order to maximize the amount o power which can be extracted rom the enironment Two cases were explored: with an imposed displacement and with an imposed orce
