Responses of Nonlinear Electro-Mechanical Energy Harvester by Means of Recurrences
Résumé
Abstract. We examine the modal response of an electro-mechanical energy harvesting device based oncharacterisation of the experimental time-series. Mechanical resonator consisting of a flexible beamand a tip magnet and nonlinear switching magnetic transducer defined as composite magnetic ringbased on a soft ferromagnet. To identify the dynamics of the response of the studied harvesting structure and the associated voltage and displacement output we used the Recurrence Quantification Analysis (RQA), estimating the corresponding recurrence rates and recurrence times.
