Abstract. Vibration energy harvesting has greatly expanded over the last few years. While linear vibration-based energy harvesting has received considerable attention in the literature, some current research is focused on the concept of purposeful inclusion of nonlinearities for broadband transduction. The energy harvesting process is performed in two steps: energy extraction and using this energy to feed electronic devices. Thus, this work discusses the use of an energy extraction device that is a chaotic non-linear mechanical device, coupled to a half-wave rectifier circuit to transform the alternating voltage generated by the piezoelectric ceramics into continuous voltage to power electronic devices. An analysis of the dynamic interaction between the two devices is done and it can be concluded that it is possible to use a mechanical device that operates in chaos coupled to a rectification circuit.
