ABSTRACT: Due to our busy lifestyles, our health is quite precarious these days. We designed a device using piezoelectric materials. Electric charges are generated on the surfaces of certain materials as a result of applying mechanical tension. The induced charges are proportional to the mechanical force. This phenomenon is known as the piezoelectric effect. The materials that leverage the piezoelectric functionality effect include ceramics, polymers, composites, thin films, relaxer-type ferroelectric materials, and crystalline structures, which have been successfully applied over the past decades. A wide range of applications has been identified in smart devices such as mobile phones, sensors, actuators, transducers, and harvesters. These materials convert mechanical strain and vibration energy into electrical energy. This property creates opportunities for implementing renewable and sustainable energy through power generation for many applications. Our research aims to achieve sustainability in energy sources for small devices by employing new and renewable energies, particularly piezoelectric energy, and establishing a system that generates electrical energy from applied mechanical force or any physical force, which can be converted into electrical energy. This energy can then be stored and used for various electrical purposes, such as charging devices like mobile phones, allowing us to compare the percentage of charging achieved through piezoelectric energy with that from traditional electricity also imagines that the phone is getting charged while you go. The resulting electric power was used to charge three mobile phones, which were fully charged in 100, 185, and 165 minutes for Nokia, Huawei, and Samsung, respectively. The charging of a mobile phone depends on the type of battery, and the amount of power generated will vary depending on the force. There is no difference in the charging time, which confirms that piezoelectricity is a clean, healthy energy source for charging mobile phones. This suggests that piezoelectricity is another renewable energy source for charging mobile phones.
