The Virtual Instrument controls an automatized measurement system and a power system even with a low expertise of the user. The VI controls with a friendly user interface our designed Harvesting Electronic Hardware and our patented test bench. The methodology presented is able to characterize several harvesting topologies and connections. The designed procedure obtains the previously unknown piezoelectric elements key parameters in road traffic environments. The VI developed calculates the Fourier model limiting the relative error between original and reconstructed signals.
