A Comparative Research on Maximized Output Power Between Disc Type and Multilayered Type Piezoelectric Energy Harvesters

초록

In this study, we analyzed newly designed ceramic-polymer composite multilayered piezoelectric energy harvesters. For comparison, two different types of piezoelectric energy harvesters were designed, and fabricated by employing the conventional ceramic and tape-casting processes. 1-3 storied disc-type and multilayered-type piezoelectric energy harvesters were compared and analyzed by considering their crystalline structure, polarization electric field, output voltage, and output power. In addition, we have investigated the optimized output powers of the disc-type and multilayered-type piezoelectric energy harvesters by employing impedance matching.
