Harvesting energy from wasted mechanical vibrations can reduce or eliminate the need to replace power sources in small devices that are in remote or hard-to-reach locations. Low power electronics, such as wireless and health-monitoring sensors, cameras, data transmitters, and medical implants, use only microwatts of power. This makes them perfect candidates for self-powered energy harvesting systems. This is achieved through various common methods of transduction mechanisms including electromagnetic induction, electrostatic conversion, magnetostrictive induction, and piezoelectric transduction. Piezoelectric energy harvesting has flourished in most recent investigations because of its ease of application and its suitability to take advantage of many environmental mechanisms for energy production. In small-scale applications, such as powering microelectromechanical and nanoelectromechanical systems, piezoelectric energy harvesting has also shown great promise. Inertial sensing devices play a crucial role in the functionality of vehicle guidance and stability control systems Compared to their conventional counterparts, MEMS gyroscopes are compact, lightweight, consume little power, and cost very little to manufacture. In this work, a novel multifunctional energy harvesting microgyroscope system using perovskite piezoelectric materials is proposed. This work focuses on developing a reliable reduced-order model for the design of a microelectromechanical inertial sensing gyroscope with broadband energy harvesting capabilities.
