Ceramic-Based Piezoelectric Material for Energy Harvesting Using Hybrid Excitation

Abstract: This paper analyzes the energy efficiency of a Micro Fiber Composite (MFC) piezoelectric system. It is based on a smart Lead Zirconate Titanate material that consists of a monolithic PZT (piezoelectric ceramic) wafer, which is a ceramic-based piezoelectric material. An experimental test rig consisting of a wind tunnel and a developed measurement system was used to conduct the experiment. The developed test rig allowed changing the air velocity around the tested bluff body and the frequency of forced vibrations… Show more

“…A GUNT HM 170 open wind tunnel with a closed measurement area was used in the experiment. The wind tunnel is described in detail in [14]. Its measurement section is a square of 300 mm x 300 mm in cross section, and the test object was in the centre.…”

“…Wang et al [ 13 ] designed a piezoelectric wind energy harvester with Y-shaped attachments on the bluff body, which confirmed the transition from vortex-induced vibration to galloping. Considering that both vortex-induced vibrations and the galloping effect have a desirable impact on high amplitudes, Ambrożkiewicz et al [ 14 ] proposed a PEH whose tip-mass is a mixed design of the bluff body with different shapes of cross-section. This device can extract energy from its environment at lower air velocity values.…”
