With the aim of using as much as electroactive parts as possible in the same electronic interface, the purpose of this work is to propose a hybrid nonlinear circuit combining piezoelectric and electromagnetic harvesting systems for significantly increasing the final output power while ensuring a relative independence to the load. The resulting technique, called Synchronous Electric Charge and Induced Current Extraction (SECICE) has been developed taking into consideration the Synchronous Electric Charge Extraction (SECE) and the Synchronous Magnetic Flux Extraction (SMFE) schemes, initially developed for the sole use with piezoelectric and electromagnetic transducers, respectively.
