Title: Masahiko Masuda: Innovator in Oxygen Sensor Technology

Introduction

Masahiko Masuda is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of sensor technology, particularly in the development of oxygen sensors. With a total of 2 patents to his name, Masuda's work has advanced the capabilities of gas detection systems.

Latest Patents

Masuda's latest patents focus on limited current type oxygen sensors. The first patent describes an oxygen sensor that comprises an oxygen ion conductive solid electrolyte, a detection element with a positive and negative electrode, and a heater element. The design includes a negative electrode installed on a wall that communicates with a small hole, which restricts the amount of oxygen that can diffuse through. The porous positive electrode and heater are embedded within the solid electrolyte layers.

The second patent also details a limited current type oxygen sensor, which features a solid electrolyte element made from materials with high oxygen-ion conductivity, such as yttria-stabilized zirconia. This design includes electrodes on both the top and bottom surfaces of the element, formed by calcining a mixture of small ceramic particles and fine precious metal particles. A cover is provided over the second electrode, featuring diffusion orifices that allow ambient gas to diffuse toward it. The sensor determines the oxygen content of both dry and humid gas by applying different voltages to generate corresponding currents associated with the oxygen ions flowing through the electrolyte element.
