Introduction

Miho Tobita is a prominent inventor based in Hitachinaka, Japan. She has made significant contributions to the field of pressure sensor technology, holding 2 patents that showcase her innovative approach to sensor design.

Latest Patents

One of her latest patents involves a pressure sensor that features a configuration where strain gauges are strategically placed on a diaphragm. This design effectively suppresses changes in sensor characteristics caused by positional shifts of the strain gauges, as well as temperature-induced variations in sensor output. The pressure sensor is designed to detect voltage output proportional to the pressure applied to the diaphragm, utilizing a bridge circuit formed by four strain gauges with identical characteristics. The arrangement of the strain gauges is such that two are positioned along the short side and two along the long side of the diaphragm, which has a thin portion extending in the long-side direction from the sensor chip.

Another notable patent focuses on a pressure sensor that aims to minimize variations in sensor characteristics. This invention also incorporates a diaphragm with longitudinal and lateral sides, featuring four strain gauges placed at the center. Two strain gauges are aligned along the lateral direction, while the other two are arranged along the longitudinal direction, enhancing the sensor's reliability and accuracy.
