Investigação e aplicação da otimização topológica na microgeração de energia em vibrational energy harvesters

Abstract

This project aims to bring explorations and analyzes about a microdevice designated MEMS – “Microelectromechanical Systems, coupled to piezoelectric materials, with the purpose of developing it for the generation of energy through vibro-mechanical excitations. This research is necessary in front of the search for new alternatives for electric power generation focused on new, more efficient and innovative solutions, especially with regard to the generation of low-power energy, sufficient to meet the demand of some electronic systems. Systems like remote communication or wireless sensors that have low power consumption can be benefited. This project has as its main objective the research and development of an structure of electromechanical microgeneration with piezoelectric materials for the conversion of vibrational energy into electrical energy (energy harvesters), using topological optimization as a tool that helps in the optimization of the deformation so that the generated vibration can transform satisfactory amounts of energy. The work will be divided into numerical research to determine an optimal geometry for the device, and will follow tests and experiments on benches, to determine the device's energy generation
