In the field of intelligent structures and energy harvesting, piezoelectric elements are considered as key elements. Piezoelectric elements are divided in two Categories; ceramic and polymeric. Polymeric elements can bear strain and have a lot more flexibility and Durability than ceramic elements. PVDFs are one of the most useable polymeric piezoelectric elements. Strain variations on piezoelectric films causes voltage changes on both sides of their electrode and makes them act like a sensor. At the following study, a PVDF sensor is connected to a Cantilever beam made of spring steel CK75 and the whole system is put on XU7 Engine flywheel teeth in a way that the sensor can operate the same way as RPM induction sensor of the car. All the tests are practically carried out and inspected. The results showed this type of piezoelectric element is capable of harvesting 72.46 V/g energy up to 600 RPM and up to this round functional similarities compared to the current sensor are occurred as well.

Keywords: Vibration energy harvesting, piezoelectric cantilever beam, PVDF, Flywheel, RPM induction sensor.
