Title: Ayako Otsuka: Innovator in Load Sensing Technology

Introduction

Ayako Otsuka is a prominent inventor based in Niigata-ken, Japan. She has made significant contributions to the field of load sensing technology, holding 3 patents that showcase her innovative spirit and technical expertise.

Latest Patents

One of her latest patents is a load sensor device having a shock absorber. This device includes a load sensor with a pressure receiver, a housing that accommodates the load sensor, and an elastic member that receives a load and presses against the load sensor. The design features a pressing member that is positioned between the elastic member and the load sensor, which includes a rigid presser capable of contacting the pressure receiver. The elastic supporter is designed to elastically deform, reducing the gap between the rigid presser and the pressure receiver when a load is applied. Additionally, the load sensor device incorporates a shock absorber to alleviate the elastic deformation of the elastic supporter.

Another notable patent is a pressure sensor that features a diaphragm on a silicon substrate. This sensor includes multiple piezoelectric element areas that change in resistance according to the distortion of the diaphragm. The diaphragm is designed to have a maximum deflection area, where the stress reaches 80% or more of the maximum stress when distorted by a predetermined pressure. The piezoelectric element areas are strategically placed within this maximum deflection area to enhance the sensor's performance.
