Title: Tsutomu Ueda: Innovator in Pressure-Sensitive Technology
Introduction
Tsutomu Ueda is a notable inventor based in Yamatokohriyama, Japan. He has made significant contributions to the field of pressure-sensitive technology, holding a total of 4 patents. His innovative work has paved the way for advancements in personal identification and cash handling systems.
Latest Patents
One of Ueda's latest patents is a pressure-sensitive sensor. This sensor includes a sheet base, an application-side and a receiving-side electrode, both provided on the sheet base, along with conducting coatings on the electrodes. The conductive electrodes utilize pressure-sensitive conductive ink that contains conductive carbon black. The resistance between the application-side electrode and the receiving-side electrode varies based on the contact area between the conductive coatings. The conductive ink is enhanced by adding 30 to 70 parts by weight of silicon dioxide to 100 parts by weight of silicone elastomer, improving its strength and dispersion. This pressure-sensitive sensor demonstrates output stability and linearity across a wide temperature range from -40°C to 85°C.
