In the present work, a hybrid nonlinear interface based on the coupling of piezoelectric and electromagnetic transducers for energy harvesting purposes is exposed. Based on the Synchronized Switch Harvesting on Inductor (SSHI) technique, the proposed scheme aims at including as much as electroactive parts as possible, replacing the passive inductance by an electromagnetic transducer. The working principle and experimental validations are presented, showing the enhancement of the harvested power provided by the active electromagnetic system, when compared to the SSHI and the standard approach.
