Introduction

Masashi Watanabe is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of piezoelectric and electrostrictive devices. With a total of 4 patents to his name, Watanabe continues to push the boundaries of innovation in this specialized area.

Latest Patents

Watanabe's latest patents include a matrix type piezoelectric/electrostrictive device and a method for manufacturing the same. The first patent describes a method for creating a matrix type device that features multiple pillar-shaped piezoelectric/electrostrictive elements. These elements are designed to be vertically arranged on a thick ceramic substrate, allowing for effective displacement-driven operation. The device ensures that the piezoelectric/electrostrictive elements are integrally bonded to the substrate and arranged independently in two dimensions. Notably, the percentage of transgranularly fractured crystal grains on the sides of the piezoelectric/electrostrictive substance is maintained at 10% or less.

The second patent focuses on a piezoelectric/electrostrictive device that includes a stationary portion and a thin-plate portion supported by it. This device incorporates a plurality of electrodes and piezoelectric/electrostrictive layers arranged alternately. The manufacturing process involves forming a laminate by layering the electrodes and piezoelectric/electrostrictive layers, followed by cutting the thin-plate member and laminate using a wire saw. This innovative cutting method minimizes the degree of covering on the end surfaces of the piezoelectric/electrostrictive layers.
