A model of an auxetic piezoelectric energy harvester consisting of a cantilever, auxetic substrate, and piezoelectric layer is developed in this study. Firstly, the auxetic harvester model with an auxetic cell is presented. Harvested power for this model is compared with a plain piezoelectric energy harvester. In the next step, the new auxetic model with trapezoidal geometry is presented. Harvested power of the trapezoidal harvester is compared with a plain harvester and rectangular harvester with an auxetic cell. All the analysis has been performed using the finite element method. Mesh size sensitivity analysis of the models is presented, and the finite element model is verified by previous experimental studies. Present investigation il-lustrates that harvested power of trapezoidal auxetic energy harvester in resonant frequency could improve to twenty times more than plain harvester. Utilizing trapezoidal auxetic booster as the substrate in piezoelectric energy harvester leads to increasing the density of harvested power of the auxetic energy harvester by 82.5%.
