Title: Yoshiaki Fuda: Innovator in Piezoelectric Technology
Introduction
Yoshiaki Fuda is a prominent inventor based in Miyagi, Japan. He has made significant contributions to the field of piezoelectric technology, holding a total of seven patents. His work focuses on enhancing the efficiency and functionality of piezoelectric transformers.
Latest Patents
One of Yoshiaki Fuda's latest patents is a piezoelectric transformer. This innovative device comprises a piezoelectric rectangular body that is equally divided into four regions. The first and fourth regions are equipped with plane electrodes as input electrodes and are polarized in a thickness direction. Strip-like electrodes are formed at the boundary between the second and third regions as output electrodes. An AC input voltage, with a frequency corresponding to a wavelength equal to half the length of the piezoelectric rectangular body, is applied to the input electrodes. This setup allows the piezoelectric plate to vibrate in a two-wavelength resonance mode. The voltage produced by the piezoelectric effect in response to this vibration is extracted from an output terminal. The transformer is noted for its small size, low vibration rate, minimal heat generation, and excellent efficiency. Additionally, the input electrodes can be modified to be formed in two or three regions, which are opposite to each other in displacement distribution, without being restricted to the first and fourth regions.
