Title: Shunichi Tatematsu: Innovator in Magneto-sensitive Technologies
Introduction
Shunichi Tatematsu is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of magneto-sensitive technologies, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of magnetic sensors.
Latest Patents
Tatematsu's latest patents include a magneto-sensitive wire and a magneto-impedance sensor element. The magneto-sensitive wire is designed for magnetic sensors, featuring a Co-based alloy that contains a higher iron content than traditional compositions. This wire exhibits zero magnetostriction and improves both measurement range and environmental resistance. The alloy's iron ratio is carefully controlled, ranging from 6.1% to 9.5%. By heating the amorphous wire at specific temperatures, Tatematsu achieves a composite structure that enhances its performance. The anisotropy field of the wire ranges from 5 to 70 Oe, with stress sensitivity indicative of magnetostriction between −30 to 30 mOe/MPa.
The magneto-impedance sensor element consists of a magneto-sensitive body that changes its electromagnetic properties in response to external magnetic fields. It includes a detection coil that outputs a voltage corresponding to the magnetic field's intensity. This innovative design allows for the application of pulse or high-frequency currents in opposite directions, enhancing the sensor's functionality.
