Double Beam Energy Harvester Based on PZT Piezoelectrics
European Journal of Engineering Research and Science
This work presents a new design and performance evaluation of an energy harvester. The generator was built in the form of a double beam mechanical structure on which eight piezoelectric elements were glued and subjected to cyclic tensile and compression loads. Electrical energy is converted from mechanical vibrations generated by machines, by means of a piezoelectric material based on Lead Zirconium Titanate (PZT). Geometric dimensions of the beam structure were optimized by a finite elementdoi:10.24018/ejers.2020.5.12.2240 fatcat:uisxtoghibftdkj3dbpb7gbq4e
