Methodology for choosing piezoelectric devices

In the context of the Brazil ID project, this paper proposes a methodology for choosing piezoelectric devices for energy harvesting to feed RFID tags, since the existence of a large number of manufacturers of different technologies complicates the choice of the most suitable one and the most technically feasible. The proposed methodology guides the search for important device parameters, starting with the acquisition of their electrical response. By manipulating data, explicit and implicit knowledge of important piezoelectric information is obtained. This methodology also considers the usage scenarios by collecting information about: vibration signatures, frequencies and amplitudes characterization, variety of vehicles types, roads pavement conditions, vehicle accelerations and speeds.
