In this study an optimization procedure for the design of a piezo-electric Micro-Harvester device is proposed. The device is simulated to analyze the interaction of the fluid with a deformable piezo-electric cantilever. A fixed D-shaped bluff body is used to generate flow deviation, resulting in a mechanical deformation on the micro-cantilever. A novel geometric parameterization is proposed to find...
The growing research interest coming from the wide diffusion of wireless micro sensors and small electronic devices has given input on several studies towards Energy Harvesting (EH) as possible alternative to their powering in untraditional way. In the EH field the use of piezoelectric materials is developing rapidly. In this scenery, the aim of this paper is to evaluate the experimental and simulated...
The aim of this paper is to model and simulate a cantilever beam as energy harvester to expose to wind vibrations. A mathematical model describes the behavior of cantilever beam and the electromechanical coupling, using piezoelectric constitutive equations. An experimental setup of a fixed configuration (dimensions, materials, boundaries and shape) is performed by means of such device and the effects...
