It has long been known that piezoelectric materials have potential to convert electrical energy into mechanical energy and vice versa, providing chances to find a variety of uses in sensors, Mechanisms and energy harvesting systems. In order to give a thorough overview of the historical development and current achievements in piezoelectric materials—with a focus on their use for sustainable energy harvesting—this study collects insights from a variety of research papers. First, we discuss how this unique property in materials like quartz was first discovered by scientists all those years ago. We then follow their adventure as they discover more advanced materials, such as PZT and barium titanate. There’s a catch, though: some of these materials involved lead, which made them bad for the environment. So, researchers started looking for safer alternatives, like bismuth sodium titanate. These days, harvesting energy from vibrations and other processes is of great importance to us when it comes to piezoelectric materials. This is really useful for creating devices that run off of electricity without the need for batteries. Even more flexible materials are being developed that have the ability to detect vibrations and convert them into electricity for use in sensors and phones. This research is historical and modern research to explain how piezoelectric materials allow the development of more environmentally friendly and effective technologies.
