Vibration energy harvesting is one of the methods that is used as energy supply for electronic devices that have low power consumption (such as sensors). With the advent of piezoelectrics and due to the properties of piezoelectric materials, they were quickly introduced as one of the most common materials for energy harvesting. Currently, vibration energy harvesting with piezoelectric material can produce more than 300 microwatts per square centimeter of power. Piezopolymers are one of the types of piezoelectric materials. In this work, with the help of EAPap piezopolymer materials, which are a thin film of cellulose, energy-harvesting beams have been made. By changing the location of the piezoelectric along the length of the cantilever beam, the changes in voltage, current and output power have been investigated. It can be seen that by changing the position of the piezoelectric on the beam and getting closer to the end of the beam, the output power, current and voltage have also increased due to the increase in the amount of strain.
